While using my laptop computer (Acer Aspire 6935G) on windows 7 I am getting unwanted forced shutdowns.

I had the problem on Vista, so chose to reformat, and restore to factory conditions, but didn't have the correct disc or partition to replace vista.
I upgraded to 7, hoping it would fix the problem, and it doesn't seem to have worked.

It occurs entirely randomly, whether I am using the computer or not, if I leave it running with just the desktop visible it will still shut down.

When I upgraded to 7, it did tell me there was a problem with the battery, which may cause the problem, but I have since replaced the battery as that had been faulty for a while.

There are no error messages, and the only start up screen I get is the run in safe mode/start normally, not the fix windows screen.

I have run scans with Avast, and it finds no problems.

If anyone has any suggestions, would appreciate it.

I don't think this is an infection, but to be sure;

Run a scan with MBAM:

Download the free version of Malwarebytes' Anti-Malware (aka MBAM): https://www.bleepingcomputer.com/download/malwarebytes-anti-malware/ to your desktop.

  • Double-click mbam-setup.exe and follow the prompts to install the program.
  • At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
  • If an update is found, it will download and install the latest version.
  • Once the program has loaded, select Perform quick scan, then click Scan.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Be sure that everything is checked, and click Remove Selected.
  • When completed, a log will open in Notepad.
  • Post the log back here.

Note: You will need to use Internet explorer for this scan - Vista and win 7 right click on IE shortcut and run as admin
Go to the Eset web page to run an online scanner from ESET.

  • Turn off the real time scanner of any existing antivirus program while performing the online scan
  • click on the ESET Online Scanner button
  • Tick the box next to YES, I accept the Terms of Use.
  • Click Start
  • When asked, allow the ActiveX control to install
  • Click Start
  • Make sure that the option Remove found threats is unticked and the Scan Archives option is ticked.
  • Click on Advanced Settings, ensure the options
  • Scan for potentially unwanted applications, Scan for potentially unsafe applications, and Enable Anti-Stealth Technology are ticked.
  • Click Scan
  • Wait for the scan to finish
  • Click on copy to clipboard or copy and paste the results here in this topic

Anything I can do?

Motherboard
Acer Aspire 6935 (CPU): 80 °C « The temperature of the motherboard is too high.

Last Boot Time: 01/07/2012 14:58:33
Current Time: 01/07/2012 15:38:25

The reason why your computer is shutting down, because the motherboard is getting it to hot. To prevent damage to the components. It think this is an hardware issue.

I would advise to ask this in the forum Hardware, my knowledge for hardware is very little. My geek knowledge is for software. This doesn't look software because of the high temperature and the fact you reformat it.
