The crashes happen every time I try to do an operation like convert a video file for use with my MP3 player or convert other music files to mp3 format in iTunes. It also happens when playing a game like Left 4 Dead, but much less so when playing, say, Civ IV. I'd think it was the graphics card, except for those crashes when doing something like converting media. Occasionally, it'll go on certain websites. The New York Post's website is a frequent offender, but last night it dropped on YouTube. I really can't seem to find any pattern here.
Months ago I was having a heat issue where this happened almost constantly, and I noticed the CPU fan was barely turning, which is why I replaced the heat sink/fan. After that things smoothed out for several months before this started happening again with growing frequency a few weeks ago. But the temp readings are consistently at 30 C. I haven't wiped and reinstalled Vista yet, but that's what I figured the next step would have to be.
