2 Windows 7 PCs Suddenly No Longer Boot
Jul 18, 2009
I've got 5 PCs here.. 2x Win 7 x64 v7100, 1x Vista x32, 2x XP Pro x32. Strangely, within the past 24 hours both of my Windows 7 PCs have stopped booting. They turn on, hard drives spin, fans come on. There is no beep, and no signal to the peripherals, including keyboard, mouse, monitor. Identical problems on both systems.
Specs on Windows 7 System 1 (2 years old):
Motherboard Asus P5N32-E SLI
CPU Intel Core 2 Extreme QX6850 Quad-Core 3.0GHz
Ram 4 x OCZ DDR2-800 Reaper 2048MB
Video Card 2 x Asus GeForce 8800 Ultra 768MB
Power Supply Silverstone ST1000 1000W
Specs on Windows 7 System 2 (1 month old):
Motherboard Asus P5Q-EM
CPU Intel Core 2 Quad Q9650 Quad-Core 3.0GHz 95W
Ram 4 x Kingston ValueRAM DDR2-800 2048MB
Video Card Asus GeForce 9600GT 512MB Silent
Power Supply Corsair VX 450W Power Supply
I suppose it's possible that both motherboards just coincidentally failed in the same day but that seems pretty unlikely. They are both ASUS. On System 2, the second system to fail, I did notice that the computer had been on with the screen saver up for a little while. Someone had been using it only about 20 minutes earlier. I thought it'd entered power saving mode and turned off the screen but when I went to bring it back up, I couldn't. I noticed that the light on the front of the box was flashing. I tried powering off by holding down the power button, then powering back up but had no luck. I also tried turning it off at the power supply and unplugging it for a few minutes but that didn't help either.

I have been running Win7 64-bit for 2 years. My boot drive is an Intel SSD. Win7 used to load very quickly. It would come up with the Windows logo and quickly flick to the login screen. Boot Performance tracked in Event Viewer - Application and Services - Microsoft - Windows - Diagnostics Performance, perational would generally report 45 seconds or so. Recently, for no reason I can yet discern, that has jumped to 218 seconds. I have looked for 101 Event IDs (application boot performance), there are a few listed, but usually with very small footprints (degradation of 300 ms). Nothing which explains the 3 additional minutes.When the OS boot now, it comes up to the Windows splash screen, and as the 4 colours are coming together, it hangs. At first I thought there was something seriously wrong, so I restarted via the power switch, and ran Startup Repair. It ran, but boot was the same. After a few more power button restarts, thinking I had a very serious problem, I sat there stumped and..... it eventually booted! The 4 colours eventually started moving again, and the system booted. That is what I experience every time now. There is roughly a 3 min pause during the boot sequence, then it proceeds as normal.Things I have tried, Updated to latest Nvidia chipset and GPU drivers.Have almost nothing in Startup when Running MSConfig,Ran Intel's SSD tool. Reports everything A-OK. Made Boot Sequence "Hard Drive" only so it doesn't search for CD drive. Ran Windows Update to ensure all latest critical patches installed (for all I know, this caused it).

I changed my Windows Media Center "Recorded TV" folder to a different partition. After I recorded a program, I was able to view it on my PC and also "PLAY TO" my TV. I lost the ability to see those files from my SONY Bravia. I can still access my PC as a server and can view other video files, but the "Recorded TV" folder shows as empty, I switched back to my original partition and still no luck.HP Pavilion running Windows 7 premium 64

My Windows 7 PC won't boot. There have been no software or hardware changes (potentially a windows update was applied that I don't know about, shutdown one night, all OK and then couldn't boot up the next morning). I get the windows 7 logo, then a black screen with mouse cursor, but I can't move the cursor. There's no keyboard response either (I don't think this is the infamous black screen of death as this typically still responds to a CTRL+ALT+DEL?). Safe Mode is no different apart from seeing drivers load, it stops at CLASSPNP before pausing for a while and then the black screen.
Managed to run the startup recovery tool, although I only get this option sometimes when trying to boot. It scans but can't auto fix the problem but reports a corrupt registry (I don't believe this is the problem though).
I removed my boot drive (which is an OCZ SSD) and mounted as a secondary drive in another PC so I could browse files on that drive. So I managed to restore my registry files from the windows backup files (windowssystem32config
egback), then replaced my SSD in my PC, but still no boot (which is why I don't believe it's a reg problem). I swapped out the SSD to my other PC again, this time I ran a chkdsk on my SSD, it found some small problem, nothing major so I fixed it successfully and swaped back to my original PC again, but still no change, still not booting. I swapped it out again, this time I had a look at ntbtlog.txt, it shows lots of inf's not loading (CLASSPNP being the last one to load.

My friend's laptop (ASUS G72GX) won't boot into Windows 7. Specs:Windows 7 x64 Home PremiumIntel Core 2 Duo P87006 GB RAMNVIDIA GeForce GTX 260MHe said it worked fine in his room and then he brought it downstairs (I'm assuming he did a hard power off by pressing the power button) and that's when it stopped working. Here are some things it does:After pressing the power button, the ASUS logo will appear (this happens during POST) and then the screen goes and stays blank.-Sometimes, it gets to a screen that gives the option of starting Windows normally or running Startup Repair.-Startup Repair hangs at random places (progress bar fills fast and ten completely stops).-If the option to start Windows normally is chosen, it eitherhangs at the 'Starting Windows' screen (Windows 7 logo does not animate) or flashes a blue screen that is much too quick to read (just a fraction of a second) and then the laptop restarts.
I can get into the BIOS options and everything seems normal, including temps (though I'm not sure how high they were when the problem started). However, upon exiting the options, the problems above proceed as normal.I also tried hitting both F8 and F12 during boot, but can't get to the screen that would let me start in Safe Mode since it hangs at the Starting Windows screen.I'm kind of at a loss here. My friend's not exactly careful with his laptop, but this is the first time I've seen a computer refuse to boot like this.

Have dual boot; XP and 7. 7 will no longer boot, asking for the installation CD. I don't have an installation CD, only the one that puts everything back as it was when purchased. Can I get a boot file that will boot from USB? Or since I can see the 7 drive from XP, could I add a file to Win7? I checked on EasyBCD that is supposed to work, but I' use RollBack and it won't work with RollBack installed. I'm afraid to uninstall RollBack since it has saved me so many times in the past.

my 3 day old Win7 Ultimate innstallation on my 3 day old computer just crashed after trying(or maybe succeding) to innstall Service Pack 1.
This is how the screen looks when I try booting. [URL]
I have tried all safety modes, last known good config. Debugging mode. The Windows 7 DVD(tells me the chosen OS version can not be repaired), none of these options worked. What else can I try?
Could this be the punishment for not getting genuine windows and using a loader? Can it be saved?

This weekend, I bought and installed a new SSD into my computer. I re-installed my Windows 7 (Home Premium x64 OEM) onto it, (fresh install, no migrate) and immediately formatted my mechanical HDD. I went into my BIOS and changed boot priority. (I set it to CD first, because I was re-installing from the disc, followed by my SSD.) I changed BIOS Drive positions, with my SSD as #1 and HDD as #2. On my Mobo, my SSD is plugged into SATA3 Port #1. My HDD is plugged into SATA2 Port #1. As soon as I got Windows installed, I started re-installing programs, setting up my admin account, and generally resetting my system, theme, Rainmeter, etc. Then I started getting messages that I wasn�t running Genuine Windows. I clicked the �Resolve Online� button, and downloaded the authenticator software, which told me I needed to buy a copy of Windows.This irritated me, because I am running a key I bought legitimately, and I have the packaging and CoA. I called Tech Support. I spoke with a very helpful gentleman. He checked out my product key. He had me activate my product, which I hadn�t done on my new install yet, and I got a �Genuine� tag to appear under the Windows Experience Rating in �My Computer>Properties�. He said I was good to go. Now, 48hrs later, I�m getting the "Not Genuine" message again. I have a screenshot of Windows claiming to be Genuine and Not Genuine at the same time. (See Attached photo.) I have installed a lot of updates since my re-install, so I do seem to be getting those. So, although I formatted the original Mechanical HDD, I have to assume there are some residual Windows files still on it, (but I'm not finding any) because apparently Windows thinks it�s running on two machines now, I assume. I�m also getting a strange message in my Boot process, which asks me if I want to Boot into Windows 7, or into Windows 7. A 30sec timer then appears and chooses the highlighted option, and continues to boot normally. This computer is custom built, and I purchased an OEM version of windows separately from the builder - legit, physical packaging - and I opened the packaging and installed it myself about a year ago. It has been fine until I installed the new drive this weekend.

I bought a Corsair force 3 SSD 60GB and I'm using it as a cache with IRST on my Asus p8z68 v-pro /gen 3 mobo (bios updated), well something has happened 3 times since. First I performed a clean windows 7 32 bits install, and installed the latest intel IRST drivers 10.8 (and now 11.2), then installed a game called SWTOR played for a few weeks everything was fine. Then uninstalled the game (20gb size) and after a couple of times using the pc, I can't shut down windows 7, had to press the power button off, then on, then a screen appears telling me intel caching is rebuilding itself and finally 0 access to windows 7.
Seems IMO like the raid 0 is not working anymore. I've never had issues with my pc and my HDD drive so I am suspecting 100% about the corsair ssd drive. I have had this issue 3 times since last March all after doing a full clean windows 7 installations, sometimes I updgraded the mobo bios other the ssd firmware currently everything is updated even the ISRT drivers however this issue still happened today again for the third time.

I was working on my computer when windows locked up and I was forced into a hard shut down, when I restarted the computer one of my hard drives showed up as invalid and my computer would not recognize it. When I tried to repair the sector to make it valid the it seemed to work, now my computer will not boot into windows at all. I have an SSD HDD set up and I need this computer as it is my main audio work station.

The problem started 3 days ago when I was playing World of Warcraft and I was alt-tabing (nothing special, just ordinary stuff). After a load screen, where the game normally starts loading stuff, the alt-tabing was inresponsive and while I was in desktop, clicking WoW icon had no effect, like I wasn't clicking it. Soon I realized Firefox wasn't working as intended, so I pressed the reset button on my case. The pc gave me an error that, if i remember correctly, was that no boot device found. I played a little with plugging-unplugging my USB devices and the problem fixed after about 10 minutes. All good since yesterday afternoon.
So yesterday I got the exact same problem while I was playing an another game, but still at loading screen. The computer boots (from zero) very slow, even getting to "Starting Windows" screen takes a minute, and until I see the windows icon (the one about the SW text) 15 minutes pass. I left home and left the pc at that icon, and when I was back it was at login screen (weird because I only have 1 account without password so I don't ever get there). I pressed my account icon and after around 10 seconds (notice the time for just pressing a button) I got the "Welcome" screen, with the circle moving smoothly. I tried to use my Windows installation disc to find a boot problem, however it takes for ever to find a problem. Also tried booting in safe mode, but it takes a long time to load (haven't left it enough hours to load, I think it got stuck at some point).
My initial thought was of course a HDD failure. I have tried removing the ram sticks, unplugged everything but the DVI cable, played a little with the HDD sata cables, but nothing. The only thing I haven't tested is PSU.All the few operations I have managed to see (like the SW screen or the clicking) take a huge amount of time. I suspect it might not be a boot, or even HDD related, error but something else. The problem so far is the speed. The only thing I have seen to be working normally is navigating in the BIOS menu (which is graphical, I have an Asus motherboard). Also notice that just before I manually rebooted my PC, alt-tabing was inresponsive (not crashing, just very slow probably).
** EDIT ** : chkdsk reported no bad sectors

I have a HP labtop and my laptop froze all of a sudden so I did a hard restart of the computer. After restarting the computer I am no longer able to boot my computer up, the screen will go black sometimes after the log in screen. But now I do not even get the option to go to the log in screen now it just goes to the startup recovery stage. Everytime I try to fix start up I get startup repair off line following by the details of 0.00000 or something like that. The numbers are all zeros in the details but I tried other options like restoring to a previous point and I keep getting errors.

Today I did a fresh install of Windows 7 Build 7232 because it was newer and also because Build 7077 would no longer boot. I have reinstalled 7077 and reinstalled 7232 twice. Windows works okay for a while and then will freeze and I will have to power off the PC and restart. But when I try to turn it back on it hangs at the Starting Windows screen. My other desktops have no troubles with Windows 7 at any build. I can start in Safe Mode but nothing else. Thanks in advance.
PS I had just finished installing Adobe CS4 software and was using Google Chrome when it froze. BD 09 is my antivirus with firewall disabled, firewall is Windows Firewall. And all are x64 installations.

For some reason my laptop has slowed down incredibly on start up. It is an HP Pavilion purchased last ovember and everything has been fine until 2 days ago. I started up and it took around 5 mins fo my desktop icons to show completely and then a further 2 mins before I could access any programs. I did a system recovery to before the problem started but no use. Any ideas before I take it back to the shop - its still under arranty.

I recently had to replace my motherboard when a power failure killed my HP Compaq nx9420, running Windows 7. When the repair was complete, the laptop would no longer boot to Windows on the internal HDD. Instead it boots to startup repair. Startup repair fails with the message, "Cannot repair this computer automatically".

Let me explain, I just noticed that when I restart my pc, the restart precess seems to hang at the motherboard screen for more then 3 times the time it does when I boot the pc from being switched off(a good 15-20 seconds at Mobo screen on restart).
The problem is I think it only started doing this after I accidentally uninstalled a hard drive driver and the pc shut down(and I think restarted). The hard drive seems fine now, the driver was reinstalled, I'm just a little concerned I could have caused a problem, or is this normal?
So the question is simple, Is it normal for a pc to take longer(at least 3 times) at the motherboard screen when you restart then when you boot up from an off position. If the answer is no then I suspect it could be something I've done to it, as I never noticed it taking that long before.
My basic pc spec is:
i5 2500
assus h67
8gb ram
560ti
I just checked, when I start up the pc normally it stays on motherboard screen for 6 seconds, when I restart it stays on the screen for 24 seconds.

All I have a dual boot Win 7 and XP, I want to remove the XP as I no longer use it. Both are active and on seperate discs, can I just format the disc? I have used easy BCD to edit the boot menu so only Windows 7 default yes.

It's a dell latitude, 1 year old. Laptop suddenly crashed and when the laptop booted it said: "no boot sector on internal hard drive". I tried repairing the boot sector with the windows repair function, but the hard drive is just empty... nothing to repair. Then I tried to boot off a ubuntu live cd. which worked. and showed me an empty hard drive with the_maximum_capacity_of_the_drive_GB of unallocated space.
Since that I reinstalled windows 7 two times, and stopped working after an hour or so. I installed ubuntu, which worked for several days. then i tried windows 7 again (clean install). And then I kept working on the laptop for a couple of hours until the "crash" happened. All the programs stopped working suddenly. When I opened anything I was shown this error: "Illegal operation attempted on a registry key that has been marked for deletion."
After that everything is lost if I turn the computer off. And I'm back at an empty unformatted hard drive. I changed the sata operation mode in the bios to different options before every installation of windows. I didn't try xp, because I don't have dell-xp cd's . Is the hard drive broken? I guess not because ubuntu works. and windows 7 also, but it just goes away suddenly... Here's a video (shot in portraitmode) of the event... [URL].

When I boot my Win7 system then the Boot Screen (where I can press ESC resp F2 to enter the BIOS)appears only for a couple of MILLIseconds.This is too short.Even worse: Sometimes the Boot Screen is completely not visible any more.How can I tell the system to show this Boot Screen for lets say 5 seconds minimum?

What I think to have caused the problem is in this previous threadnyway, after doing that last fix and booting the computer the next day, I got an error saying I may be a victim of software counterfitting, followed by a black wallpaper with a not genuine message at the bottom right. I need to get it working again so I can get updates, and I've lost my Windows 7 Home Premium key which makes this all the more difficult to fix with normal tech support from Microsoft

I built this PC myself. It was built around 5 months ago. I installed Windows 7, and it said it was perfectly genuine and everything. I bought this on eBay from a person with 99% Positive feedback and with 2300 stars, so I'm sure it isn't pirated. Now randomly I have a black wallpaper and in the bottom right corner it says Windows 7, Build 7601, This copy of Windows is not genuine. I've scanned the computer fully for viruses with AVG and Malware with Malwarebytes, and found no problems. [code]

I built my first custom PC about 4 months ago. I bought windows 7 ultimate off Ebay, installed it, entered my product key, installed Microsoft Security Essentials and everything worked fine. At the time it said my copy of windows 7 was genuine.Now 4 months latter my computer randomly pops up with a message telling me my copy is no longer genuine. Microsoft Security Essentials is no longer running, my desktop background has turned black and in the bottom right hand corner of my screen there is a message saying
-"Windows 7
-Build 7600
-This Copy of Windows is not genuine"
As far as I can tell my copy of Windows 7 is genuine. It came with a sealed COA, a proof of License label and holographic discs.

I bought Win 7 Ultimate for 2 installs over a year ago. I bought an Asus Laptop a year ago which came win the 7 Home and upgraded to Ultimate with no problems at all. 3 months ago I bought a Dell with 7 Home and upgraded it to Ultimate. Again no problems! About a week ago I started getting multiple error message on the Asus stating that my Windows 7 was NOT valid. Now today I am getting the same messages on the Dell. Not able to get help from Microsoft which keeps insisting that these operating systems are invalid. Two huge questions: IF this is actually the case why would it be such a very long time before getting these error messages, Also, what are the options now I am being told there are 30 days remaining before the OS on both systems locks up?

I have a problem on my Windows7 laptop when clicking on internet shortcut links..When I try to opening a link, Windows no longer knows what to open it with and tries defaulting to MS Word. I've tried selecting in the usual way and ticking the box to have either IE or Firefox to open them, but it just won't work.

We have been using a Windows 7 machine and an XP machine for some time now - they are using the same workgroup name, and were sharing files using the Public folder on Windows 7, no problems. The XP could also connect to the printer, which is hardwired to the Windows 7.
They are both using wifi in our building. The wifi, which is owned by the landlord, used to be called Ourwifi. A couple weeks ago, the power went out in our building and then there was a problem with the wifi and the internet/cable company came out and changed it. It is now reconfigured as Ourwifi2. It is password protected.
Since that change, both the Windows 7 and XP computers are able to access the wifi and use the internet, but now they cannot share files. As far as I know, nothing on either of the computers settings had changed.
The Windows 7 computer was turned OFF when the power went out; the XP most likely was ON (because that user tends to leave it on all the time). Since I've been trying to reconnect them, I may have changed something by accident.
So here are the settings in the Windows 7:Network and Sharing - Under advanced sharing settings, password protection sharing is OFF under "home or work" as well as under "public." Workgroup is listed as the same one as the XP computer (ourwkgrp). In Windows 7, under active networks, Ourwifi2 is listed as a"work network" Windows 7 has Norton running; I'm unsure if it has had any auto-updates that may have changed accessiblity settings. I can't find in the Norton settings how to add all those TCP and UDP numbers suggested in a post elsewhere that might help it find the XP machine. On the XP machine -- XP can see (or thinks it sees) the Windows 7 computer over the wifi -- if I look at "view workgroup computers" in the XP -- Windows 7 shows up, but if I attempt to connect, I get a message saying it is an invalid path, cannot be viewed over the network.
XP cannot print to the printer connect to Windows 7. It can't see the printer b/c I can't expand the Windows 7 folders that show up under "view workgroup computers."
how to access anything if you send "change this to on," etc.

Last night after some modem problems which may be coincidental Windows 7 PRO (OEM) suddenly de-activated. It now will not re-activate either by the normal method or by telephone. No hardware has been changed and to my knowledge no new software was installed although some of course may have been updated. I was simply attempting to browse the web. It came with a new build and has been fine since November 2011. Checking the error logs I find these related messages. Code: Genuine state set to non-genuine (0x00000000) for application Id 55c92734-d682-4d71-983e-d6ec3f16059f Code: Acquisition of genuine ticket failed, hr=0xC004C4A2) for template Id 66c92734-d682-4d71-983e-d6ec3f16059f I ran the MGADiag tool and it produced this.
