Graphical glitches with Radeon 6850

[onick]

Until now I have never had any problem with this card. Started with crashing and showing vertical lines or grey screen when i played movies. Then progressed to showing only 640x480 and 256 color. I have tried to swap different driver, reinstalled windows (now driver doesn't install, and gfx card is showing up as atombios 16mb), even while installing windows, or running linux live cd, everything was showing in 640x480 and 256 colors. Everything in BIOS shows correctly, even the opening animation of "starting windows" shows correctly, but the moment user account and password windows show up, everything in low resolution and in 256 color. I have an old nvidia 7100GS when swapped places with 6850, everything shows up properly. I am not at a loss and sort of gave up on that card and using 7100gs since. Anyone have any idea on what could be wrong with my card ?

its death... at the moment of vertical lines or grey screen with movies was a good indicator of faulty vRAM. and progressively the card died =(... bake it.. =D

sigh! sort of realize it has became a lost cause now. funny how my old nvidia 7100gs is still ticking while ati 4870 (after a year suddenly decided not to power the display) and 6850 both died from unnatural causes.

ive had plenty of nvidia cards and mobos (im looking at you 980i) die over the years, but my 9700pro is still going......

its luck of the draw...

Bake it or bury it.

If baking is not the remedy for a fix

I can only suggest this:
