Symptoms described by (system drops power a few minutes after opening a file; HDD scan and slaving didn’t help) point to either intermittent hardware failure or a low-level software/driver problem. Replies from , and correctly cover the basic directions; below are practical next steps and a short triage order that were not yet detailed in the thread.

Start with data safety: back up any irreplaceable files before further tests. Then try a live-USB Linux session (or any OS boot media). If the machine stays up while running the live environment, the fault is likely Windows or a driver. If it still dies, that strongly suggests hardware.

Hardware checks that narrow the cause quickly:

  • Run a dedicated memory tester (bootable memtest-style tool) for several full passes; persistent errors mean bad RAM modules.
  • Swap the power supply with a known-good unit or use a PSU tester/multimeter. Sudden shutdowns under light load often point to PSU instability.
  • Do a careful visual inspection of the motherboard for bulging/leaking capacitors, burn marks or loose connectors. Replace or have the board serviced if caps are bad.
  • Check the CPU cooler: verify fan spins, heatsink seating and thermal compound. Thermal shutdowns typically happen after a short load period.

Software/log checks to complement hardware tests:

  • Collect any Windows minidump files from C:\Windows\Minidump and analyze them with a crash analyzer (BlueScreenView/WhoCrashed) to get stop codes or faulty driver names. This follows ’s request for an error number.
  • Run an offline/bootable antivirus rescue scan if you still suspect malware.
  • Check drive SMART attributes for reallocated sectors or pending errors even if a cursory HDD scan reported OK.

Suggested quick triage order: backup → live-USB test → memtest → PSU swap/test → inspect caps/connectors/fans → analyze minidumps → consider OS repair or reinstall only after hardware is ruled out. Always unplug and discharge the system before opening the case; use basic ESD precautions or seek professional help if unsure.

Could you please give more information? (when it restarts, what programs you are running when it restarts, etc) I would say you have a virus, but I can't know for sure until you give a little more information.

Boot into safe mode. Go into control panel, then into system. Under startup and recovery (called Advanced System Settings on the left in vista) make sure that "Automatically Restart" is NOT checked and that "Write an Event to the system log" IS checked.

Next time it it should give you a BSOD instead of just rebooting. Post the error number shown here and we can help you.

I just checked it now. The problem is that when you open a document, file, or anything it will shutdown by itself in a few minutes time.So you will need to turn the CPU on again,and it will continue with the same problem. I have slave and scan the hard disk but still there was no improvement. I am not sure wether it is the mother board or the power supplier which is causing this problem.Thank you.

Overheating?

Did you do what i said by the way? That way we can rule out whether its a driver or HW issue

go into safe mode and disable all the startup processes and programs, this way we can rule out any buggy software and then concentrate on the hardware, also start up the pc with minimum hardware(1stick of memory, onboard graphics,one hdd etc)
