Yesterday and the day before yesterday I used my computer to download material from the shareware program Limewire, and I encountered some viruses there. As I use Avast, it detected them as soon as possible and I deleted them.
After a while I entered a site with viruses (a megaupload link with a trojan) and avast did the same.
After some hours of use, my PC started freezing more and more. (By freezing I mean it completely freezes and I needed to manually reset and reboot to have a good startup as well)
After a day I tried to open the pc and it stopped functioning completely. The extremely weird thing is that :
When I turn it on, the computer starts its fan and then closes after 5" , then it turns on by itself , and this carries on until after 10 minutes when it closes itself in a sleep-mode like manner. The PC does not boot .
The screen does not show anything , apart from the orange light that indicates no signal.
-I did not perform any hardware changes ever.
-I tried stopping it for a while so it would fix itself, moved the case, nothing.
-The day before that happened, I did a spyware check and it found a few things.
-I tried removing the power link from the SATA Hard Drive to see if the problem is in the BIOS, and my fears were right, it's probably a motherboard problem , but since it began with a virus, I am asking is there any way to reset it (the bios) any button on the motherboard?
