Hi me again. (lol) So I got a virus awhile back and my brother fiddled with my comp and fixed it temporarily. He still hasn't wiped everything out yet. Anywho, everything seemed fine until my computer started to lock up and then shut off. It doesn't matter what I'm doing, it will just shut off. Sometimes I can be on the computer for an hour without it shutting off and sometimes the first thing I do it happens. Anyone know what this could be? I've heard about this happening if the fan isn't working properly to cool it off, or there might be dust in it, etc. But it really isn't that hot when it shuts off. My brother said he would fix it today but I guess he forgot. He always forgets things. I don't want to bother him though. It's so annoying!

Also, after it shuts off, I wait a little bit before turning it back on. Is it okay if I turn it back on or should I just leave it off? I don't want to ruin it by it being turned on and off all the time. TIA!

I also forgot to add that when the CPU shuts off, the keyboard is still lit up and the monitor has that blinking light.

I guess you should try a deep virus scan to find out what's wrong. Don't stint; activate the full gamut of your antivirus' scanning protocols. Search your archives, your logfiles, recycler data, system volume data, compression data--everything. I'll bet you'll find a virus. If you don't, try to switch the computer on and off many times; sometimes the heat (or cold) gets to the mobo and locks it up. If even that doesn't work, try voltage stabilization; maybe a surge or short is doing this to your comp.

If all this doesn't work, call your vendor to send servicemen over.

I've done a virus scan but nothing pops up. As for the voltage thing I really have no clue how to do that. Thanks though. :thumbsup:

I'd say that you need to address your infected status...first and foremost.

I will suggest that this thread be moved to the malware section of this website.

Hello I am movin this to the Am I Infected forum from XP so we can proceeed.


Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Just wanted to update saying my computer is all fixed now. It was actually a power supply issue! :thumbsup: My brother got all the viruses or whatever wiped out too. He should really do this for a living and get paid for it. LOL Maybe I should tell him to get on this board!

Thank you for letting us know.
Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
