I just bought the following: Abit AT7 Max2 Abit Geforce TI 4200 512 or PC3200 DDR oh and an 2200+ AMD XP Im cooling with a Koolance water cooler and cpu temps are around 37c - 40c(while playing games). My locks up everytime Im in a 3d game. I was playing UT2003 on single player, and it locked up four times in a row. Sometimes right when I enter game play, other times when I'm a few minutes into the game. I have not attempted any overclocking yet. My previous hardware setup showed no problems while playing these games. I also played Virtual Pool 3 single player and it froze after about 4 minutes of play. I ran 3dMark2001SE and it froze during the 8th or 9th test. I think it's the multi-texture 2nd swirl test(or something like that). I will run it again to see if it freezes at the same spot. It only freezes while in playing a 3d game. It never freezes any other time. I'm assuming it's the Geforce, but are there any settings I can change to troubleshoot this? Im gonna probably stick back in my other video card to make sure, but it's a pain in the butt to mess with the water cooler once it's attatched to the card. Oh, and drivers? Ive used the newest drivers from the nvidia web site and also rolled back to the drivers included with the card. Any suggestions anyone?
