Is my GPU causing speckles on the screen? Plasma TV
I recently put together an HTPC capable of gaming on my plasma tv and whenever I play either Oblivion or Medieval 2 Total War I get either a bunch of black specks that come and go all over the screen and with Oblivion I get a bunch of neon green, pink, and blue specks that pop up all over the screen. It doesn't happen with any other game or when I am on the desktop doing any thing else like watching blu-ray rips or browsing the internet. The card I have is a 4870 1gb. I don't know the correct term for what I am seeing so I havn't been able to find anything online for the problem I have having. Thank you for the help.
Edit: The temp is around 55 degrees C when I am in game so I don't believe the card is overheating.

Did you try different game settings... like disabling the AA and @ diff resolutions...?
Depending on how big your screen is, you might be seeing artifacts because of a lack of vram.
