graphics card keeps freezing my computer!
I just bought a replacement GPU for my system and most games seem to crash after less than a few minutes of play. The screen will just lock up and make this awful, distorted buzzing sound which forces me to reboot. I have updated all the video card drivers and I'm using direct x 9.0c since i'm still on XP32. I bought the GPU second hand off ebay but it is in virtually new condition, the seller stated this expicitly, and it was posted in an anti-static bag and original box. I really hope the card is not faulty and I don't want to accuse the seller of this until I am positive it is the problem. It is definitely not a PSU issue as the video card is a 7600GT which only uses 45 watts and requires a 300watt power supply, which I easily surpass those minimum requirements. I even refitted the card in the PCI-E slot and made sure it was all in place and secure, whilst obviously taking anti-static precautions. What is causing this? I just hope it is only hardware related. I would really appreciate quick replies as I need to get into contact with the seller promptly if there is a defect with the card.
