Alright, I've exhausted everything I know to try, anyone have a better idea? I picked it up used off this forum, so RMA'ing will be difficult.

Sapphire 128MB RED PCB AGP Radeon 9700 NON-Pro.

Has been running great for about 2 months. One day I turn it off, come back a few hours later and turn it back on and I've got a corrupted bios screen. All further screens including windows are corrupt. Corruption equotes miss colored character blocks, random characters across the screen, a "garbage" screen, not flashing just continuous garbage. NOTE: This garbage screen also comes up on the Radeon's default screen that states you must plug in the external power connector if you didn't plug it in before power-up. This indicates it is not a power problem with the external (floppy power) connector.

Here is what I've done attempting to solve the problem,

-Remove/Reseat the card
-Check/Clean the heatsink fan
-Clean card's AGP contacts
-Reflash the default bios
-Use a can of compressed air to clean the card of dust/materials

None of this helped, except, strangly leaving the card out of the system or cleaning it with compressed air. If I leave it out of the system long enough (20-30 minutes, 5 minutes doesn't help), it will work initially. The computer is completely stable in Windows and 3D with no artifacting when the system comes up with no garbage (about 1/10 tries). If I reset, or restart the system it continues to work. However, powering it off and back on again causes the garbage to come up immediately.

I have verified it is the video card specifically by removing the 9700 and replacing it with a Radeon 7500, it works perfectly fine. I have also installed the 9700 in another system where it continues to produce garbage.

Does anyone have any advice? This 9700 has 3.3NS Infineon RAM.

Thanks!
