is my 6990m dead ??

I've been suffering for months trying to get my 6990m to work

the card shows on device manager also it shows OK with the bios and diagnostics ..
AMD Radeon HD 6900M Series (Microsoft Corporation - WDDM v1.20)
with yellow exclamation mark ..

but whenever I try to install ANY driver (dell, amd, modded ..etc) on any version of windows, a white frozen screen shows when it starts installing the display driver (instead of flickering and turning the card on)

even if I tried to disable the intel graphics (via unlocked bios), the computer doesn't boot ..

I don't know if the problem with the card itself (then why it shows ok with diagnostics and shows on bios and device manage !!)
or the problem with something else ..


buying a card will cost a fortune and shipping it also,
but how can I make sure the problem with the card not something else

please help , as video games are my runaway from stressing and exhausting emergency medicine

 

Have you tried reinstalling windows from scratch and being a 6990m user, I will recommend you Win7 since Ive seen massive fps drop in games under Win 8.

 

I tried many versions of windows 7 and windows 8 ..
the whole thing started when I repasted my gpu and upgraded the ram and installed everything from a scratch on ssd

 

While I don't have a 6990M my gpu started showing issues, like the yellow "!" by it and the laptop would let me install the Nvidia driver but no matter what, it wouldn't recognize the gpu fully. (It saw it was a GTX 675M, but nothing would work, no video acceleration, nothing. After re-installing Windows and trying just about everything in the book other than dissembling the laptop (Since it's still under warranty) I figured that it may have overheated somehow and fried. I'm afraid the same thing happened to yours. While there are differences in hardware, issues can be the same. Your GPU is most likely dead or very very close to dying. Luckily you still have the Intel gpu from the looks of things, my laptop had the intel completely disabled. So I really couldn't do anything. I sent my laptop in for repair, since it is still under warranty. Assuming yours isn't, your have to bite the bullet and buy a new gpu or just buy a new laptop. (Since you said you repasted and such, you probably are confident enough in buying a new gpu, and which it may still be cheaper than buying a new gaming laptop.) That's more up to you though. Good luck!

 

Might be worth reseating the GPU since you repasted.

 

I believe it is the GPU unfortunately, you have done everything that there is to do to isolate the issue.

 

how can I get new 6990m or 7970m to Egypt

and if it is dead, why it shows correctly the model name on device manager ??

 

If there is a fault in a transistor in the shader block basic functions like the PCI-express interface etc can still work but as soon as it tries to do processing work it would start throwing errors.

 

Your issue sounds exactly like what happened to me when I installed my ssd and tired to put windows 8 on it. It would show up fine, but I could not get the card to work. I ended up going back to windows 7 after 4 fresh windows 8 installs. It has worked great ever since. Liked mentioned above it would be a good idea to reseat and repaste the GPU.

 

still with the half dead card ??
how can I fix it or what is the best replacement??

 

Would baking the card possibly fix this at all? I haven't heard of the that method used much anymore, but I was just curious if it was worth a try.

 

Yes do the oven trick. Worth a shot.

 

??
baking ?
oven ??

 

Yes it's to heat the solder and try to reapply it to the die etc etc.

 

I don't get it ?
details or a link ??

 

I have almost the same problem with my computer. I have a SAGER and my GPU failed recently, too. I haven't tried a clean reformat yet, but I will do it soon as my last option. At least I can run on intel graphics for now, but it's pretty crappy and I can't play games or do video editing. I don't know if it's worth replacing it (close to $600), or just buying a new laptop, which I don't particularly want to do since this computer has been awesome. There must be a place online to buy a cheaper replacement GPU, no?

 

I really hope I can buy something cheaper ..
600$ is my salary in 6 months

Check the nbr marketplace. I got my 6990m two years ago for $300 on the nbr market place and it's still running strong.
