Have a Radeon 9800pro that died recently....about a month ago.....well....initially did all the normal troubleshooting bs and nothing worked....then I looked on top of my sound card...and there lies the video card fan...

, I got no life out of it so I figure before trying to power it up, I go up to CompUsa and get another fan/heatsink and put that on....so yep, this voids my warranty and it still don't work. ANy thing I can look for that I can replace or did it most likely overheat the GPU ?
Thanks
Tim
