I don't overclock. I have a a 3.0e Pentium 4 prescott. its so fucking hot. i have a huge copper heatsink, Its like cooltech or something, the really good silent 36$ a year ago one... my computer shuts down during random things. for example I own two music cd's... i know pathetic, but I tried ripping(edit: using windows media player) the first one, 3 times my computer shut down, then 1 once my second one, which just decided not to bother finishing. the proc temps measures about 70*C-75*C the inside of my case goes from 45*C-50*C My computer sometimes shuts down randomly during guild wars and also during CS:S. its not a WINDOWS IS SHUTTING DOWN shutdown its a boom, black screen, ABIT Is7g2 mobo (i think thats the numbers) radeon 9800 pro video card, 420 watts with 2 hdds and 1 cd-rom, I had a dvd rom but thought it was power issue so i removed it, still does it. I can't really think of anything else to say... any ideas what the fuck is wrong with my computer?
