So my pc for a while likes to randomly shut off, with no warning etc.
Pretty sure its down to overheating, Despite having a pretty big fan on the front which blows out air, and one on the side panel, and the psu, and a big cpu heatsink/fan etc etc.

My ram's pretty shoddy because a couple of sticks died, leaving me down to only 2GB,

So what I'm thinking is grabbing another 2GB of ram, and a couple of extra case fans, but I'm still not sure this will solve the problem, anyone got any ideas?
