Turned on my machine a few days ago and got a black screen on Windows 7 bootup.  After many days of fiddling, I still cannot get anything but a blackscreen, regardless of what version catalyst drivers I use.  I can only boot windows with the 6990 drivers disabled or uninstalled.  Also, the bios screen now has red lines running across it. 

If any1 has any last solutions, please let me know.  I have tried pretty much everything I could find on google.  Card was never overclocked and was only used for a couple months.  Unfortunately I added the Accellero Twin Turbo 6990 cooler fans, so my warranty is void, which is why I'm posting here as a last ditch attempt.  Thanks

 

Solutions Attempted:

-Tried multiple PCIE slots, tried multiple hard drives, tried multiple windows 7 installations, used memtest (no errors) and driver sweeper, played with many bios settings, tried many versions of catalyst, tried booting in low res, tried multiple monitors

Has it ran ok with the aftermarket cooler on there?  It may just be that you tightened down the screws too much.  Try removing it completely, clean the old thermal grease off, put new on, put the cooler back on and just get the screws snug, don't crank down on them.

I know that its a pain to do, but better than just throwing it away or sending it off for RMA service.

Agreed. If you overtightened it you could have cracked the GPU or flexed the PCB enough to snap some electrical connections, BUT reapplying it without so much pressure could fix it. Remember to tighten the X plate screws until they no longer freely turn but not so much that they are difficult to turn (in otherwords, you want it snug).

Another question, which TIM are you using? You don't want to be using diamond based TIMs on the bare GPU.

I installed the aftermarket cooler when I first bought the card and it worked fine for the two months of use.  At this point, I don't really see what loosening the screws would do, but I guess I'll give it a try anyway.  Sorry, don't know what a TIM is .  Thanks for the replies.

Tried removing the twin turbo cooler and reattaching, no changes.  Finally got to try the card in a totally different machine, got the same problem.  Concluded the card is toast. 

This is a good example of why NOT to modify your video card.  My gaming days are over.

No, this is an example of why not to modify your video card WITHOUT doing research first. They had the same problem with the Accelero Xtreme 5970, it was killing DVI ports or entire cards because the idiots at Arctic didn't design the thing right and didn't even provide correct instructions.

Anyone else disturbed that he removed and re-attached a heat sink without knowing what TIM is?

As for the rest, I agree that AMD's stock coolers are a very poor design, and cards with custom cooling are a much better experience.  The down side is that if you plan on moving to liquid cooling, the custom cards are more likely to be incompatible with full cover blocks.

Personally, I'm sticking with water for the foreseeable future.  I don't think I could tolerate the noise and temperature of air cooling again.
