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