Power Loss, And Windows Tools For Analyzing Possible Damage?
Jul 15, 2010
Today some maintenance personnel were working on my bathroom in my apartment. I stepped out to take care of some errands while they worked. I put my computer into sleep mode (NOT hibernation - Actually sleep mode). When I got home, I realized that all of the clocks were flashing "12:00" and my computer was powered off.When I talked to the maintenance crew, they said that they had encountered a problem in the bathroom and caused a short. This, in turn, tripped the breaker that my computer room was on, which they then reset. This means that my computer, at minimum, experienced a hard power loss while running. It may or may not have experienced a surge (!), though it is on a surge protector. And the surge protector did not have its safety lights lit to indicate a surge.
Unfortunately, since using the computer I'm noticing a lot of oddities. I played some TF2 to unwind, and for the first time ever it crashed. My Video Card got stuck in "uplocked/3D" mode. Web browsing was slower than I'm used to, and overall it seemed like the computer picked up a lot of 'chugging' where it hadn't before.Is there some method to diagnose the general health and well being of my computer in windows? Are there tools beyond CHKDSK that I can run to locate problems that may have occurred as a result of a power surge? I'm concerned that the power loss damaged my components significantly, and I'm not sure how to diagnose the problem or determine if it's all in my head.
Here are my specs, if that's important:
Windows 7 Pro x64
i7 core 920 CPU
eVGA x58 mobo
eVGA GTX 275 Video Card (197.13 drivers)
Corsair 850 W PSU
6 GB RAM

I had a power loss while running on battery (it still showed power left, but suddenly shut down anyway) and when I restart, it reports that the Windows is not activated and Window is not genuine and system might be a victim of "counterfeiting."
Is this a virus (I have MSE on continuously and about once a week scan with Malwarebytes)? I have run 'sfc /scannow' with filtered output ('findstr /c: "[SR]" c:.....logsCBSCBS.log" and it appears as usual.
How can I lose my Windows activation?

My computer wouldn't shut down, even with holding in the power button, and so I just let it run out the battery. Then it wont turn on. I tried holding down the power button to clear out any charge that might be remaining. I have managed to get it back on, but I have to make a connection at the clip where you plug the power button ribbon into the mobo. Also, this is the second time I have had to do this. The computer works fine afterwards...or seems to anyway.

My computer was turned off during the update process and I am getting the blue screen. After launching the start-up repair I am told the problem cannot be solved although there is a patch preventing the system from starting. My registry files precede the date the problem occurred, I have tried to restore but there is no restore point, I cannot start in safe mode. I have launched bootrec.exe and ran FixMbrFixBoot and also RebuildBcd and none have worked. I know I will probably have to go the long way around and pull the data from my disc and do a clean install but just wondered if any of you Techsperts had a quicker fix so I can spend the rest of my life in awe at your magnificence?

I had issues with my computer displaying symptoms of a faulty PSU. I was shutting down instantly whenever I ran intensive games for too long.Soon after those issues went away, I started getting random freezes, crashes, and BSODs. I finally tracked this down to a bad version of firmware on my SSD, and upgraded it by upgrading the firmware version, doing a 'secure erase', or something along those lines, as OCZ calls it, then installing a brand new copy of Windows 7.Everything went fine for a little bit. It's been 1-2 weeks or so since I upgraded the firmware.Over the past few days, I have noticed random ... near-shutdowns. Basically, my monitor was off, and my computer was unresponsive - but the lights and fans and what-not were on.I thought something tried to shut down my computer or something, and didn't think much of it. Maybe a weird Windows Update, iunno.Note: The hard reboot function on my computer (a tiny button near my power button) that usually works without issue does not work when this happens. My computer still has power, but it seems like it just... died. No monitor connection. No response whatsoever.A simple holding down of the power button and then pressing it again when it turns off seems to work, although the power up from that point takes a bit longer than normal.
Today, I have seen this first-hand 2 times. Just today. I was doing something, the sound started skipping - at which point my monitor disconnected, although for a few seconds after, I could still hear the guy I was talking to on Skype, and he could hear me. A few seconds and the sound dies down, and my comp is completely gone. Power still running as I already mentioned.Do note that this has happened both when I was running an intensive game and when I wasn't running much of anything - certainly nothing intensive.
I've already replaced my PSU, upgraded my SSD firmware, and reformatted my main HD (not data drive) and reinstalled Windows. I ran memtest a little while ago and it ran w/o issues, 2 passes, 0 fails.FYI, I've checked temperatures. My computer is not at all overheating.S This has been going on for months. I use this computer for gaming, programming, and work.
Edit: My computer just "died" again - for the third or fourth time today. I'd like to note that for 2-3 seconds right after this happens (i.e. right when my monitor goes dark and my computer stops being responsive), my fans get very loud - much louder then they normally would. After this, my fans go back to the normal volume level that they are usually at.The only thing notable in my Windows Event Viewer is that there was a generic, unexpected loss of power. It leads me to information about a "Kernel Power Event 41", with the following link:[URL]

I had a power loss while installing a windows update about two months ago. Ever since then my system will hang either on logging off or shutting down.I have tried making a new user (No Help)it hangs in safe mode also.I also do not have a list of prior updates in control panel since this problem.The system works fine other than that.

Disk defrag will analyze the disc but when I try to defrag at the point the process reaches "PASS 1, 2% REALOCATED" the process stops, neither the mouse or touch pad will work. This has been happening a for some time now. I have cleaned out programs not used anymore, etc. I am using 116gb and have 174 gb free / 32 bit operating system, 3gb ram, windows home 7 premium, service pack 1.

I upgraded my computer from Vista to Windows 7 (tech do it at Best Buy). Didn't have problems until a round mid June. Uninstalled some programs, did scans with Malwarebyts (found a bunch of malicious software), cleaned with ccleaner. Cleaned c drive. Scanned for viruses with micorsoft security essentials (nothing found). When I try to install my new webcam computer shows blue screen with ... windows has shut down to avoid damage and today I it was doing scan for viruses and froze again. Sometimes computer shuts down while simply clicking on a link in a website. A few weeks ago I used ccleaner to clearn up the registry and I fear something may have happened then as I've recently read that one should not mess with the registry. There are some other things I've tried but can't recall at the moment.

I noticed it was really slow coming on I tried to play a game but it wouldn't even load that up which I played earlier in the day fine. And now I got a message saying windows has detected a problem and is shutting down to prevent damage to your computer I don't know what to do?

After becoming unable to download identified updates in Windows Update, and also being unable to search for new updates, I did a detailed scan with Microsoft Security Essentials which identified and removed some malware (Exploit:Java/CVE-2010-0840.IZ).
Since Windows Update still wouldn't work I restored my settings from last Friday with no improvement. Using Fix problems with Windows Update gets stuck on Fixing problem.
I then tried to do a reinstall as an update, but the installer was unable to find any updates (or rather it was forever* trying to locate any).
On a tip from a friend I looked in the hosts file but it was unaltered. *Forever is a relative term but in this case it's 90+ minutes.

I am trying to dual boot windows 7 and XP but I keep running into the same problem. Windows 7 was installed first and I am now trying to install XP. I partitioned my hard drive and then I inserted the Windows XP installation disk and the "Install Windows XP" option is greyed out. I rebooted my computer and booted from the disk and got the following error message:"A problem has been detected with windows and has been shut down to prevent damage to your computer.If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.Technical Imformation:*** STOP: 0x0000007B (0XF78D2524,0x0000034,0x00000000,0x00000000)"

I have windows 7 family version. My laptop is an ASUS K52F. I use MSE. For some reason, my firewall protection has been switched off. I don't know how long it's been off. Recently, I've started getting intrusive chinese pop ups when I open my firefox browser. I get emails from paypal saying someone is trying to access my account. I live in China and have to use internet for banking. Can I be sure that I am clean of any bads things?

My SSD with Windows 7 is O.K. - I can restore backup images.My Primary SamSung HDD is O.K. - I can restore backup images.My Secondary WDC HDD is what held my images and they vanished.Fortunately I have duplicates of most on an external HDD.I am currently scanning and attempting to recover from the Secondary HDD the few images that were not backed up.My WDC HDD was GPT which I have read is safer than MBR - but that did not work out well for me.I am thinking of cleaning it and using it as MBR,especially as Lost Partition Recovery is so much faster and easier on MBR than on GPT disks.If I use Windows Disk Management to make the WDC Disk "Offline" would that protect from a Linux glitch,or is it only Windows applications and tools that take any notice of Offline/Online settings ?Would the WDC be better protected if I refrain from allocating drive letters to the partitions on the WDC,and only access via the alternative Disk Management option "Mount in the following empty NTFS folder" ?
Windows always Recognises first the WDC HDC as Disc 0
and then the Samsung HDD as Disk 1
and finally the OCZ SSD as Disk 2 (even though it is connected to SATA port 0)
My Secondary WDC HDD was GPT with several partitions.I booted into a Linux Boot Flash Drive that I had slightly tweaked,and Linux aborted on start-up and the system restarted so I allowed a normal Windows 7 start-up.Windows Recognised the WDC HDD as Disk 0 BUT for some reason the GPT style Disc ID was a much shorter MBR style Disc ID.As usual the Samsung HDD was Disc 1, BUT IT WAS OFFLINE due to a Disk Signature Conflict.By Launching Macrium Reflect I saw that the WDC HDD was using the same 8 digit signature as the Samsung HDD.Windows Disk Management shows this WDC HDD as NOW being an MBR DISK with
100 MB Basic RAW Healthy(Active,Primary Partition)
25 GB Basic RAW Healthy(Primary Partition)
25 GB Unallocated
14 GB Free Space
531 GB Unallocated
MiniTool Power Data Recovery v 6.6 is able to perfectly recover 300 GB of files from the 531 GB Unallocated space,but two of the larger 6.5 GB files have the correct names and sizes but fail the MD5 checksum validation,so I know that some sparse damage has been done to a little bit of the information on the sectors.

I have a HP Compaq 610 on Windows XP, 64bit, and I decided to wipe the hard drive clean before reinstalling Windows. However, after cleaning the drive, I am booting from the CD and after installing the first part, it stops at the point where Windows would have to start installing and I get the blue screen, and the common error message "A problem has been detected and windows has been shut down to prevent damage to your computer."0x0000007B(0xF7A2652C, C0000034).I have run a test on the hard drive and the memory, and it's all in perfect order?

I have been researching the topic and am at a loss after around an hour of fruitless research. I recently upgraded from xp 32 bit to windows 7 32 bit. I want to upgrade to 64 bit so theres more RAM available and cannot find any information on doing it without discs that doesnt use USB or something. Got an external hard drive what the hell do I do? I downloaded the files but then couldn't open of course bc they were 64 bit files or whatnot.
(my cpu is capable of running it)

My Tungsten e2 has no desktop software working in Win7. I'm at a loss.Also, before I upgraded from XP Home, my address database failed repeatedly to sync. I finally diagnosed it as erroneous record ends in the database. I am not sure how to get Win7 compatible software tools to fix this.

I keep getting a message on a bluescreen, often when the cpu comes out of sleep mode, that it is shutting down to avoid damage or something. I also often have trouble getting ctrl alt del to work. Recently, we removed several viruses, and hijackers from the computer, that made it so I couldn't even google search, and its only been doing it since then. As I write, malwarebytes said it was removing threats. I have scoured everywhere I could think of and removed almost all unnecessary programs, files and downloads. Could there stll be a virus? Could a previous virus have corrupted the comp irreversibly?
