Question Is my R9 M290x GPU dead ?

[Zakaveli]

Hey everyone was hoping to get some tech help for my Alienware 17 laptop. Was playing a game when my computer crashed. Restarted the computer and got no-POST problems, something I've got before but this time shutting down and powering off didn't fix the problem. Eventually I got the computer to boot to safe mode, where I uninstalled the AMD display adapter, and then could restart into windows normally.

Now my AMD card is unrecognizable. It doesnt show up in Device Manager and running CCC gives an error of "No AMD graphics card found or it is not functioning properly". Every time I try to install the correct graphics driver, the installation halts at 40 % and the computer crashes. The only thing different about my computer from pre-crash is that I've turned off fast boot. I ran DDU and uninstalled all drivers before proceeding to install new ones.

Is their a definite test I can do to tell me my GPU is kaput ? I've gotten a good four years out of it, at semi-overclocked speeds. I've read on these forums that the 290x have several issues, are the laptop versions troublesome as well ?

TIA, Zach

Boot to a USB drive with linux on it. grab a USB drive, a copy of rufus and a linux distribution.
http://distrowatch.com/ has tons of differing linux distributions and download links. I personally am fond of linux mint with cinnamon.
https://rufus.ie/ the utility used to extract the ISO file to the USB drive.

use rufus to extract the selected ISO to the thumb drive. it will make the drive bootable and you can run linux from the drive once done.
Reboot into linux and proceed to test the hardware. connect to internet, watch videos, await problems.
if linux is good and stable the issue is most likely inside windows or otherwise software related.
this is a test of the hardware.

you should be able to test the GPU under linux. if its kaput here, its kaput everywhere
