For donkey's my old pc would crash randomly 2-3 times a day, with the odd few days off, usualy when trying to multitask too much. 80% of the time it was when I was camming on msn, I just thought the memory or graphics card couldn't handle it but it also would crash sometimes when watching video clips. It was also slowing down so I bought a brand new one just. 1gb of ram, didn't bother with vista, my bog standard XP was put on, a reasonable graphics card 256Mb Nvidia 7300GT I think that's reasonable anyway and I saw a marked improvement, new pc multi tasked with no probs. But just now it crashed while camming again!! No one else I know has this problem so it's not like msn or aynthing, could it be my cam? It's a logitech express thingy and it is 5 yrs old. You can see when it's going to crash the cam framerate slows right down then freezes but then does the entire pc!!
