is my GPU fried?

Recommended Posts

I have a Sager NP9150 with an AMD7970M. Last night, my screen blacked out while I was watching a video, audio was still playing just the screen. I restarted the laptop but it wouldn't get pass the windows logo screen. Tried several times but windows doesn't boot. So this is what I did:

-formatted the laptop

-installed a fresh copy of windows 7

-boot up

-install drivers(except AMD 7970M)

-reboot and everything works fine

-install AMD 7970M driver, installation stuck at a black screen with a blinking underscore

-restart, stuck at windows boot logo

-restore back to before AMD drivers were installed

-boot up fine

I've tried this like 4 times now and most of the time it gets stuck at windows boot logo, and once it just BSOD during the windows boot logo screen. Does this mean that my GPU is fried? Are there any ways to confirm this before I buy a replacement GPU?

have u tried reseating the card, repasting it, checking the proper placement of the thermal pads on it, as well as cleaning out ur system from dust in the fans and heatsinks? if the issue still persists afterwards, the gpu might indeed be damaged and ull only be able to operate using the igpu. u still need the dgpu installed tho, otherwise ur laptop will freak out and shutdown

I'll disassemble the gpu later and if it still doesnt work It's probably the dGPU right? Cuz I don't wanna spend money on a new GPU and realize that something else is broken instead of the GPU.

Just realized I don't have the tool to unscrew the hexagonal shaped thing that holds the card in place

u can just use a regular philips flat head screwdriver.... :)

well, if it still doesnt work then chances are good its the dgpu. there is, however, an additional chance that its the display cable or the display itself. but since the issues only arise once u install the AMD gpu drivers, its very likely the dgpu :)

Look for another dgpu. Best GTX970M or K5000M/GTX680M.

you can also test your ram, as well as a hard drive. They sometimes get tricky too..

I second that, mine 7970m behaved in exactly the same way when voltage regulator on the card said "goodbye".

have you tried installing an older version of the drivers? at least you can remove any chance of it being bad driver set. Were you running it overclocked?

I will repaste the GPU before doing anything else. Clean the fans to get more airflow.

Maybe the Temps are too high and the cooling system doesn't work.

Sorry to bring up a somewhat old thread, but did you have to replace your video card afterall? Im having a similar issue with mine and am wondering what to do.
