I have a PC that runs fine, except that whenever I run a task that demands above normal or high CPU usage (like malware scans, defragger, etc), it shuts down forcing me to power it on again.
How can I fix this? Maybe changing some BIOS settings?? I suspect it might be the CPU fan not working efficiently as it should or some other thermal issue hardware related, in which case a simple BIOS setting change won't do it.
Any ideas? Thanks

I'd suggest it's overheating, you could try reseating the processor+heatsink

Run HWMonitor too see how hot everything gets and at what point is shuts down.

It just forcefull shuts down at once (screen goes black)? No BSODs?

Thanks Jarrod, I did reseat the CPU+heatsink.

Menthix, the PC forcefully shuts down (screen goes black) with no BSOD.
I just finished cleaning the internal parts of the PC, there was dirt beyond imagination, to the point of clogging all fans (CPU and case fans). After cleaning everything, I ran CPU intensive tasks and no shut down. I hope things keep stable. I will download your suggested monitor and post temperature results.
By the way, this is the MOBO of the PC:

Thanks.

Good news! The PC has been running smoothly for 24 hours with no shutdowns. Furthermore, I installed HWMonitor and CPU Burn-in and ran the CPU at 100% usage for 30 minutes and everything stable. Before the Burn-in the CPU temp showed 45 degrees celsius and it reached a maximum of 64 degrees during the burn-in test. The fans also responded well by increasing the RPM during the burn test. So apparently the cleaning of the fans+case solved it.
