Computer Failing To Boot
Jun 18, 2011
last night my computer just shut down out seemingly for no reason and when i tried to power it back up it was asking me to insert a boot device
i was planning to reformat in a few hours anyway so it didnt phase me to much so i continued to reformat the computer with no issues then once it had finished installing and i got to the desktop it just powered off again except this time it wouldnt load past bios it just kept restarting. the intersting part with the restarts was that the bios would restart but the power to the computer would not get interrupted. Also its not always the exact some position that it decides to restart some times it will be within 1 second sometimes i get to the desktop only for it to shut down again if i try and do anything
i have tried swapping out parts to identify the faulty part. no luck. ive stripped it down to its basic parts ( cpu Mobo ram n gfx) still same thing happens i dont even have the HDs plugged in so i dont believe it to be a virus on the HD. ive tried flashing the Cmos by taking out the battery for half an hour and this seemed to work but it asked for bootmgr so i reformated the HD again only for it all to start happening again.only this time the power does turn off some times.
i have checked the temperature of the CPU and its sitting on around 47 degrees so nothing out of the ordinary the cpu coolant gell is a bit dry but given that there doesnt seem to be a heat issue i dont know why that would make an immediate difference

I found my laptop hdd had several bad sectors. Lacking the cash to just buy new i did a full format to get them flagged as unusable. After that took 17hours i installed windows 7 ultimate x64. When it needed to do the necessary restart it failed on the bios screen (the mobo logo intel for example). I tried gettin in the bios to change boot order and cant. However take the hdd out and i can boot from cd or access bios options etc. hdd back n boom fails still. However the processor is still working hard.

got a bit of a serious issue. I've got a Corsair SSD that's no longer booting. It was setup as 1 partition (C drive). I've attempted use the Windows recovery tools via my installation disc but it doesn't even list my hard drive or partition and thus fails to detect the Windows installation.My first thought was a corrupted MBR so I attempted to use the command line tools from the Windows install disc, i.e.bootrec.exe /fixmbr etc. However I get "the system cannot find the path specified" error.I even tried removing the hard drive and putting it into an external enclosure and plugged into another computer via USB. However the 3rd party computer fails to recognise the drive (probably for the same reasons).

I shut down my system after installing the latest set of Win7 patches about 3 hours ago and now it refuses to boot. Tried to restore previous points with no luck, they all give the same result as before, it simply gets to the 'loading windows' screen with no animation and just hangs there.
In repair it passes all of the tests before giving the reason for not being able to boot as "due to Windows patch", I'm at somewhat of a loss here...
This is on a completely legal copy of Win7 64.

I work at staples, and 3 days ago a costumer arrived with a toshiba laptop, it was falinf to boot in to normal mode, so I started it in safe mode to do a backup, but then an other technician reboot the machine, now it does not boot even in safe mode, it gets stuck loading a .sys file.I Tried to get access to command prompt with a windows 7 DVD but for some reason the hard drive is not listed, so i have no access to it, I can't even re install windows b/c of that, but still the fact that even it start loading tells me that the machine do have access to it.I extract the hard drive and tried to connect it to an other computer running XP, through a IDE-USB 2.0 adaptapter, the leds turn on indicating that the hard drive is working but the computer doesn't recognize it.

I've got a hdd with Windows 7 installed that recently wouldn't boot past the startup screen. The drive is showing up in BIOS and I was able to connect the suspect drive to another pc and back up my important data. Now I'm in the process of getting it to boot into windows again but none of the recovery options are working.
Here's what I did: the drive appears fine when plugged into another pc Booted into recovery and ran the Startup Repair several times, each time I'm presented with the same message: "Windows cannot repair this computer automatically". In the Diagnosis & Repair details it doesnt list any errors codes till the bottom which then says: "Boot Manager Missing or Corrupt" Error Code =0x2
Then I tried to run Bootrec.exe but when I typed in bootrec /fixmbr and bootrec /fixboot I got a "The request could not be preformed because of an I/O device error". This message appeared during both bootrec attempts.

I have Windows 7 RC1 installed for some time, dual-booting with Windows XP. And that worked like a charm. But a couple of days ago I installed Ubuntu on the Windows XP partition (after formatting it with ext3, of course). But the thing is, I have been trying to boot into my dear Windows 7 ever since, with no success.
It didn't show in the boot manager, so I changed the menu.lst in Ubuntu. Thus it can be seen, but to no avail, as it does not work. I have tryed fixing it with the Windows 7 installation DVD, but it did not work. And I really ran out of ideas; also I would like to keep both my OS-es as they are (all data), if that's possible somehow.

it started about a few months ago, when my computer wouldn't let me play games or Internet videos one day suddenly, the screen would turn green and it would say a "graphic driver failed and has now been recovered" i updated the drivers and it fixed it for ages up until yesterday. i moved my computer onto a new desk and suddenly it started going weird again, it was failing to start up, crashing 2/3 times when it was on the windows logo, then crashing and emitting a annoying buzzing noise, which i fixed by updating the system and graphic drivers again, but now it's gone back to doing the "graphic driver failed and has now been recovered" error, stopping the video and or window that i'm using like msn or skype for instance. also sometimes the screen will just go a bright white and it has to be reset because you cannot see anything else on the monitor. tried with different monitor still same issues.

I don't know if my PC is dying a slow natural death or if an outside insult caused it. During a recent thunderstorm, a power flicker turned off my computer. After rebooting, I had no Internet access. That problem seems to have been simply a bad cable between the router and the cable modem, however I did have to fiddle with the tcpip settings. But while checking cables, my wireless Logitech mouse quit working. I plugged the mouse receiver into an empty USB port next to the one it had been plugged into on the rear of the machine, and it worked again. The other port is still dead. Later I found that one of the two USB ports in front of the machine no longer works. I can still use it to charge my phone, but it pops up a "Device not recognized" message if I plug a drive/camera/phone/etc into it. No conflicts are shown in the device manager. I would feel safe in assuming a power surge from lightening had popped something on the MB causing the failure, but there's another possibility. The day before all this happened I purchased a cheap 4-socket USB expansion hub and used it in one of the front sockets to plug in several devices, a scanner and my phone and camera cables. Has anyone ever heard of one of these hubs causing a blown circuit? Strange that the failing sockets are in two different physical locations.

I have just run PartedMagic on a new Windows 7 system to shrink C: in order to be able to create an E: (Data) partition. On rebooting, I get the following error message: Windows failed to start.
A recent hardware or software change might be the cause.
To fix the problem:
1. Insert your windows installation disk and restart your computer.
2. Choose your language settings, and click "Next."
3. Click "Repair your computer."
If you do not have this disk, contact your system administrator or computer manufacturer for assistance.
File: Windowssystem32winload.exe
Status: 0xc0000225
Info: The selected entry could not be loaded because the application is missing or corrupt.
As it is a new machine, it was supplied with no system disk and I don't have a Windows 7 Installation Disk to hand. I guess that either the boot sector has been corrupted, the partition table has been corrupted or most likely that the system partition has been moved slightly.
Incidentally, the system is an Acer Aspire 5742 According to PartedMagic, the partitions are now allocated as follows:
unallocated - Size = 1.00 MiB
/dev/sda1 - NTFS - PQSERVICE - Size = 15.00GiB - Used = 12.27GiB - Unused = 2.73 GiB
/dev/sda2 - NTFS - SYSTEM RESERVED - Size = 100 MiB - Used = 33.59 MiB - Unused = 66.41 MiB - boot
unallocated - Size = 7.84 MiB
/dev/sda3 - NTFS - Acer - Size = 488.27 GiB - Used = 27.17 GiB - Unused = 461.11 GiB
/dev/sda4 - unknown - Size = 92.79 GiB
I suspect that the unallocated 7.84 MiB is the cause of the problem and that PartedMagic realigned the "Acer" partition.
I imagine that PQSERVICE contains recovery data of some sort (like Acronis)?

2 Days ago my desktop running windows 7 ultimate 64- bits suddenly crashed, showing nothing but a black screen a bit less than a minute after starting up a game. A few seconds later my computer automatically rebooted and the repair tool launched. After it was done I took a look at the report and all it could find that was broken was ci.dll, the same as in previously mentioned topic. I ran CHKDSK and scf /scannow after that, but they couldnt fix anything or find any bad sectors. I could not boot windows unless i disabled driver signing as well, however I never get any BSOD's. My system is also a bit slower as well, but not that slow. After looking at the previously mentioned topic i downloaded FRTS64 and ran it as well, I've attached the log. (No, I did not run the code that you warned not to use on a different system and on a different machine )I'm also experiencing the same browser issues. When i enter an invalid URL I'm being forwarded to the url... website, my ISP. Also the first two times I tried to open my browser nothing happened. I waited about 15 seconds, tried again and then it opened.
I think it might be a virus as well, im using P2P a lot as well though i havent downloaded anything weird in a long while. My last 100-ish downloads (all fansubs for 2 anime series) have all come from the same site which i trust. however i did recently download a patch for a game, but that came from a site that is also used very frequently, and i havent heard of anything similar from friends/friendly gamers who downloaded the same patch.

Yesterday I disconnected a useless usb socket and ever since i am getting the message failed to boot when switching the pc on, I have tried taking out the bios battery and left it out for more than 5 minutes, I have tried my windows install disk and tried repair from that but issue still exists. I am running windows 7ultimate 32 bit, and the bios is phoneix, that's all I know.

I'm writing this from a different computer because I can't even get onto the internet on mine.Pretty much all programs fail to run. When I double-click on the icon, I get the usual spinning "loading" circle and then nothing happens.When I try to open straight from a saved file, I get an error message. For example, whenever I try to open a word doc, I get this error message: "There was a problem sending the command to the program."Symantec Endpoint Protection has been turned off and every time I go to the Action Center to turn it back on, nothing happens. I get the usual message that asks if I want to allow the change and when I click "allow," nothing changes.I've done several system restores, even in Safe Mode, and they have all failed. System repairs have all failed too. Obviously, virus scans are out of the question and Windows Defender (one of the programs that actually will run) keeps telling me that there is no malicious software to be found on my system.
This all started yesterday afternoon. I was running Firefox as usual and had a word document open that I was typing in. I walked away from my laptop and when I came back, there were three pop-ups on the screen from a virus that I had just managed to get rid of several days before. I closed them out and was preparing to run Malwarebytes when my computer shut itself down suddenly. There haven't been any pop-ups or anything that would indicate that this is a virus. However, I tried the same fix that I used to remove the virus the first time (copying the Malwarebyes file 'mbam.exe' to the desktop and naming it as 'mbam.COM' so that it will open) but even that does not work. I've tried the regedit fix that I've found in forums here but that didn't work either.

Here is the log:Checking file system on C:The type of the file system is NTFS.One of your disks needs to be checked for consistency. You may cancel the disk check, but it is strongly recommended that you continue.Windows will now check the disk.

I've got a problem that came up recently and I think it might have something to do with one of the latest Windows 7 updates. Most of the time when I open up My Computer, it scans for a really long time and shows nothing(ie.no HDDs, Optical Drives or Network Locations) and in certain folders the icons and thumbnails are completely missing. I'm using Windows 7 Ultimate 32-bit.

I am running an Advent desktop PC and its stats are as follows; Intel Core i5-2310 CPU @ 2.90GHz 8GB RAM Win 7 64 bit.The problem I am having is when ever i boot up the computer it shows the Advent logo-screen where I can access the boot menu etc but then it goes to a black screen with a cursor/underscore flashing in the top left... This screen stays for quite a while and I am not sure if it stops because of a key I have pressed or just because it has run its course but after it disappears the computer goes back to the logo-screen for a moment and proceeds to boot up as normal except slightly slower than usual.It is a relatively new computer and it has no problems running at all once the boot up is complete it is fast and as friendly as ever.

Win 7 Home Prem SP1, 64 bit, 8 gb ram. Only using the screensavers that come with Windows, no matter which one I select at varying times it will fail. I can normally reboot and it works again for a time or switch to a new selection where it will work for 2-3 weeks again. I can't find any information on others experiencing the same issue and have been using numerous virus/spyware apps to find anything. MS Security Essentials, Avast, Stinger, Housecall, SuperAntiSpyware and only find tracking cookies.I know it would help if I could get the exact error message and will update when I do get a chance to write it down.

I have tried 3 times backing up my system to an external HD I have. Each time, it gives me an error saying it failed. I also see an error code: 0x81000015The strange thing is I have backed up to this HD previously with no problems and now it's not working.The HD has a capacity of 500 GB and currently has 225 GB free. I have cleared out all the backup related information off it and try again and it fails as it gets towards the end of the backup process

I recently built my new rig (specs in profile). Now last night, I was running Prime95 to get an idea of my stock temps, and Core 3 failed (expected x, returned y). Fearing the worst, I reran it, and it again failed, but on a different core. Just to eliminate any RAM issues, I did a couple of passes with Memtest, and seems to be alright there.

I have been tearing my hair out with my network disconnection issue - OK builds pre 7048 broken after 7057 to 7100. I have a Realtek 8139 NIC. I have tried all sorts of drivers none of them fixed it. Last night I thought I would take a difference approach.
The status windows showed the NIC had received 2,590,---,--- packets within the the first ten minutes of turning on the PC before failing, so some service was chewing a massive amount of data. I used the resource monitor and found that it was PID 4 - SYSTEM, this seemed a bit strange as nothing was running.
It then suddenly occurred that with all my video files sitting on a server on the network maybe it was Media-center indexing the files. So i removed the locations from media-center libraries and instantly the network settled down and there was hardly any traffic. I put a network link into my local video folder so hopefully it wont index the network drive.
I will run it like this for the next couple of days to see if it fixes it, should everything be OK its a bug Microsoft

I had a Vista home premium. I updated it to windows 7 premium. It is 32 bit. A lot of my updates have failed. I get code 800 b0100. I have looked it up on the net. I was wondering if I should put my discs in for the windows upgrade and run it thru again over the top of what I have... I also have win 7 64 bit on my network and it was original/ I have no problems with it. Barb aztzu has chosen the best answer to his/her question.Click here to view the answer that was selected.

It seems some others are having a similar problem but thought I had to start my own post,Yesterday and this morning my pc refuses to boot initially. Sometimes it goes to the POST and stops there, sometimes to the windows 7 screen and stops there. I managed to start in safe mode but the only thing odd in there was 'C: was ok, A: (floppy) ok, D: was renamed 'F' and E: was ok (I have a TSSTcorp DVD drive and a Lite-On lightscribe drive).

Got a netbook that's been running Windows 7 for over 6 month no problem, today tried to boot up and no luck - black screen with the yellow bar running along the bottom for hours. Tried the startup repair which then gave me the chance to restore - picked this and same issue was running for hours with nothing happening. Now put Windows 7 on a USB and trying to repair though that but seems to be the same issue?

I've tried numerous times to try and update Windows Updates (trying to update on a new computer: Lenovo Thinkpad T530) but every time I shut it off, it says it's updating and it looks like it's doing fine but when I turn it says it's configuring Windows updates and it always gets stuck at the 15% mark and then says Windows updates failed, reverting changes. The error is: Error code 80071A9 I've tried Microsofts Fixits and the readiness update and all that stuff but it doesn't help at all.It's really bugging me now because this is the second or third time that my computer went to a black screen saying that it needs to check the disk (I can't remember the exact wording right now). It says the disk is fine every time but it still worries me to have this for the second/third time.

It is a Toshiba Satellite L655-S5150. When powering it up I get the Toshiba start up screen and I can hear the fan working. It seems to proceed normally then a screen comes up that says windows failed to start. A recent hardware or software change may be the cause. I am not aware of any changes to either one. I get two choices. Launch start up repair(recommended) and start windows normally. With either choice it attempts to start up but then the screen stays black. I can move the cursor around normally but that is as far as it goes. I can get to the bios using f2. The version is 2.30 which appears to be the latest. I can also get to the advanced options. I have tried the repair your computer, safe mode, safe mode with networking, and safe mode with command prompt but it always ends up with the black screen. I am also able to get the the boot menu. They don't have a boot disk or recovery disk for me to use. I have tried using another monitor with the same results. I have also tried unplugging the computer, removing the battery and pressing the start button for both 30 and 60 seconds with no success. I have done a little research and it sound like he may have the zero access root kit.
