My friend had perfectly working but slightly older windows XP system that he\nused for gaming. He wanted to start using it as a secondary workstation for\nhis photography business to batch process pictures but the software he uses\nrequires Win7 64. All of his parts were supposedly Win7 compatible and the\ninstall went smoothly (he updated everything to the latest drivers/bios he\ncould find). So far the photoshop stuff runs just fine, but when he surfs\nthe web pages refuse to load completely or if they do load the graphics are\nall messed up (sometimes its all horizontal lines sometimes the screen is\npartially blacked out) and occasionally the computer will flash to a second\nof completely black screen. I've tested the power supply and every thing on\nthe network side including trying another NIC that I know works just find\nand everything thing checks out there so I'm assuming that it's the graphics\ncard (nvidia 6800GT GV-N68T256DH-N) but I thought I'd check in here for a\nsecond opinion. I know he is running the absolute latest nvidia drivers and\nthe card is compatible according to microsoft, but I can't think of any\nother reason the computer is giving these problems... especially when it\nruns rock solid under XP.
