Seems like this is my year for video problems. What I've done to try to eliminate this problem:tried several driversreplaced power supplyrun memtest for 8 hoursre-installed FS 3 timestried the card on other machine - same problemtried other card in machine - problem goes away...and moreAny ideas?Thankshttp://forums.avsim.net/user_files/171632.jpg

Hmmmmm....... Wow, most of the steps to try to resolve this you've already taken i see. Have you checked the Global profile and make sure opengl extension limit is set to off, MAYBE it resolves it, there have been some instances that they cause artifacts/corrupt display on certain systems.....Ok this is a long shot, mandatory none the less. You power cable that connects to you GPU. See how it has two connectors. Make sure that each connector has its own cable to the PSU. Meaning nothing in between. This so the card has its own direct route to the PSU and no other HW get juice from that same cable... However if that dont work, i think best to do an RMA for it... :(
