Ok well my RAM is fine, I put in an old 512MB stick that I used in my old build, did the same thing, so I have determined that is has to be 1 of 2 things: the video card, or the PSU. The PSU seems like it would have enough power don't you think?
I have a 400W 12V @ 19A PSU powering 4 80mm case fans, 1GB RAM, 64 3000+, 6600GT, Optical Drive, HDD, and case lights. I am guessing that the 19A just isn't cutting the cheese.
But it could also be my 6600GT. I am skeptical because a lot of people are having these lock-ups. What do you guys think, is it my PSU or my video card?
