Please Help! Vista 64bit keeps crashing!

Hi all,

I was just wondering if anyone could help me. I just purchased a new HP system with Q6600 and 4GB installed on a vista 64 bit windows. I have also installed a 9800GTX+. Ever since i got the system, it has been doing random crashing when I was trying to open avi files, rmvb, jpeg, crashed once when I was on RivaTuner checking the system temperature, and crashed once when I was starting World at War. The clock speed for everything is at default. I have tried to reinstall the nvidia drivers, video codec, but it is still crashing randomly. The screen will crash with black rectangles all over the screen and will be restarted after 10 seconds or so. The GPU is not overheating as it runs at around 50 degrees while idling and I have installed a Enermax 535W psu. It seems to me that power and heat are not the issue. Please help me out!




Here is the crashing report after restarting, and I have only got this once, all other crashes had no report.

remove the 9800GTX, does it still crash? sometimes, the gpu is just faulty with no relation to temp, or power. Best bet is to try to test that gpu in another computer, and see if you experience the same problems. if it works, then RMA the hp computer...
