Help! PC crashing

[Sleekit]

Hi all, my brothers pc (my old one) freezes shortly after booting into windows forcing a restart but when its restarted nothing appears on the screen. What i'm thinking it maybe is the southbridge overheating, the stock fan that was on it broke and now ive just got a small heatsink on it (see below)

Anyone got any ideas?

I assume you've cold booted into safe-mode to check it's not a driver issue?

When my old memory was dying a while ago I used to have to boot twice to get into a stable Windows.

Yep tried safe mode, it even fails in the BIOS

I ruled out the graphics card, then when I went into the BIOS i noticed it was only reading 2.5 out of 3GB of my RAM, so I removed one stick now its reading 2.5 out of 2.5 sadly this doesn't help.

Is it possible for a virus to disturb the BIOS?

Or is it my southbridge overheating?

when you said it reads 2.5gb of ram, maybe one of your rams has somehow got broken. have you tried booting it up with the other one in it own? virus that affect the bios are extremely rare. i personally think its a hardware problem. how many rams do you have?

Its either going to be a motherboard problem or a ram problem.

i think it might be a faulty motherboard

is it still under warranty?
