Have a EVGA 7800GT PC-express. in an ASUS P5N32-SLI board. When i boot to windows the picture gets curropted and choppy. The video is bad even in safe mode and during booting. I replaced the video card with a cheaper one and it works fine.
Checked the power supply (Thermaltake Pure Power-680apd) and its fine.
Is there anything else i need to do before i contact the manufacturer of the card for a replacement?
