My PC shuts off completely at certain points, unable to tell when exactly, except the power light stays on. Don't know if this is a hardware problem or maybe a virus. Whenever I try to run a virus check with AVG or run an Ad-Aware scan, the computer shuts off every time.

A little information about your system may help.

Check your power settings in control panel to make sure this is not a power saving function coming on unexpectedly.

In addition to AdAware get:Reboot your computer in Safe Mode and run the anti-virus scan and anti-spyware scans there.
If you are not sure how to boot in Safe Mode there is a tutorial here: Safe Mode

See if that helps :thumbsup:

Thanks for the reply.

I looked at my power settings and they are fine. I tried running the AVG virus scan, and SpyBot scan in Safe Mode and the same problem occured, the computer froze and shut off.

Should I post a HJT log? Is there anything else I can do?

It either sounds like your computer is overheating, or there is an issue with your power supply in your computer. Does it restart after your computer is on for a while? Do all the fans appear to be working on your computer? You could blow them out with a compressed air can -if you have one. Is you computer on a surge protector or UPS?

Can't rule anything out at this point...

My computer doesn't restart after it is on for a while, the fans seem to be working fine, and I do use a surge protector. I understand what you are saying about the computer overheating, but isn't it weird that every time I run a virus scan or spyware scan it shuts off.

There would be times when i use the computer for several hours and if runs fine. The problem started occuring more frequently after I was infected by a trojan "rdriv.sys" which i got rid of.

Why don't you post a HJT this log in the HJT Logs and Analysis Forum.

Good luck.

Make sure the hibernate function and screensaver functions are off.

Another thing to do would be to download Everest Home Edition and see what temps you are operating at.

I downloaded everest home edition and checked the temps.

Motherboard 39 C (102 F)
CPU 92 C (198 F)
PWM 44 C (111 F)
Seagate ST380013AS 47 C (117 F)

Are these values normal?

The CPU temp looks high to me.
What processor are you using? Should be under motherboard, CPU, in Everest.
Something might not be right with your CPU or heat sink fan.

Yes, if you're operating your PC in Death Valley, anywhere else NO!

What's the room temperature as a matter of interest?

Like Joshuacat says you don't seem to be getting any cooling effect to the CPU. Is its fan running? Everest reports fan speeds, look there - at that temp it should be running at about 3000rpm.

Maybe your system is badly blocked with dust? Shutdown, turn off the power and vacuum out all the case vents, then get a can of compressed air and blow out the CPU heatsink ridges (might want to do this outside if its really bad). Also blow out the power supply fan and vacuum the power supply vent holes. Check your graphics card for a clogged fan as well. Keep the vac hose and your clothing away from the motherboard to prevent static damage.

hth :thumbsup:

I think I pulled off the right specs. I put an arrow next to what the max temp for your CPU is. Your reading is off by 22 degress. It was 25 degrees where I leave today...and that's hot for Canada for this time of year :thumbsup:

By the way, i probably should have mentioned this earlier but i do have problems with my graphics card. First of all its an ATI 9600 AIW and it doesn't have a fan, just a heatsink. I am not able to play any games cause the computer will just freez and shut off. But i still wonder why the problem occurs when i run a virus or spyware scan.
