Have I killed my graphic card?

[tseug]

Hey guys, I went out earlier after just installing windows 8 and setting up a miner for my R9 270X and when I came home, all it shows is the windows 8 activation screen. As in, even if I reboot into linux, it just shows the same static image of the activation screen with a mouse pointer in the middle.

Seems my card is just displaying the last frame it "saw". Is there any way of clearing this and getting it to work again or is it totalled?

Not sure if this is the right forum but any help/adive would be appreciated. Has anyone had this happen to them?

Maybe it's just the case that Windows 8 takes over your PC and stops you installing anything else?

What happens if you pull the graphics card out and plug your VGA into the motherboard?

That's definitely not something I've ever seen before, and I've seen a lot of computer problems. Have you tried taking the card out and testing it in another system?

There shouldn't be anything in the buffer if you turn the system entirely off, it's volatile memory.

Try the card in a different computer.

Heh nah, I already had linux installed (not using secure boot) and verified I was actually booting into it by logging in through SSH.

Sadly I don't have onboard graphics to try. BUT.. the problem solved itseld (see further down)

That's what I thought...

Anyway, for some reason the card now works and still I can't make any sense of it.

I tried powering off for a while to let things cool down completely. NOTHING.
I tried switching the PSU off for a few hours. NOTHING.
I tried reseating the card into the pci-e slot. NOTHING.
I tried a different HDMI port. NOTHING.
I gave up, left it over night. Next morning? still NOTHING!
Contacted sapphire and amazon, and long story short, amazon said they'd refund me (even tho it's way past the 30 day return period.)
Then tonight, just now, I decided to give it one last try before packing up for return. Nothing was changed besides the system being down for even longer than I tried before (more like 24 hours, previously it was around 10)... IT WORKS!

Really really weird. Good that it works, sucks that there's no explanation but even tho it works, I might consider returning to amazon anyway. I can rebuy a fresh card, or even upgrade using the mined coins + the refund.

Still deciding what to do but for now, some more mining.

Thanks for the suggestions guys, sorry I don't have a better explanation as to what the heck happenend. I'd LOVE to know how something like that can resolve itself.
