1. Get the latest motherboard driver package.
2. Remove the case cover to sniff out if it's heat related.
If the card was running in some hot box it could have become damaged and you'll have to replace it.
Hi all, any help you all can lend would be much appriciated. I have been having a problem with random lines in games such as Counter-Strike, Sims, etc. By lines, I mean there are just random distracting lines in the game. This has been going on for several months, ever since we got a new graphics card (nVidia 6600GT). To counter this, I have downloaded the newest graphics drivers, new directx, and have cleaned out the dust and readjusted everything in the comp. I have also run virus scans if that may have had anything to do with it. I'm running out of ideas, and google hasn't been too helpful. I dont know what other information you might need, but throwing out some ideas would be really helpful. Thank you to all who respond.
