Has my GPU died?

[Gman109]

This morning on my HTPC, everything was working normally, when out of the blue my screen blacked out. New TV, it's been odd now and then, so I figured NBD, I'll just reset it. I noticed it wasn't actually off, and when it powered back up, my desktop was at a resolution of like 640xXXX, and my nVidia sound had changed to something I'd never seen before. The option in windows sound to change it back to my normal setting wasn't available. I could change my desktop resolution, but it still looked...odd, some of my settings for desktop sizing had changed.

Reboot PC. I notice that the size of the screen writing for the bios is now much larger than usual. PC needs several reboots to post to Windows welcome screen. Once I'm in to desktop, same result as before with the odd sized icons/desktop/browser/etc.

Check Afterburner (I don't have this card overclocked, it's a 3090, the last of my old GPUs which i\s why it's in the Home Theater PC). Heh. Well well. Core clock is 210.0, Memory is 50.8 now. WTF?! Try to use Afterburner to change clock settings/results. No go. Hardware monitor confirms the MHZ readings/results. Nothing is hotter than usual though. Voltage is now .738 Volts, which I THINK is normal IIRC.

Tried a simple game from Steam I know was working a few weeks ago, Doom. Crashes to blue screen when I launch it. Reboot, try again. Crashes again.

What do I do now so far as further diagnosing (I'm a NOOB. NOOB NOOB NOOB at this sort of thing).? Is it fairly certain this card is now finally toast? No big deal, I'll just buy something to replace it, but if I'm missing something here I'd prefer not to have to (I'm cheap in addition to being a noob). One thing I should mentioned that I noticed, the only other thing with power on in the office when this happened was a sound bar, and I saw that it was giving the same message on its screen as when it's being powered on/off. Did I possibly get hit with a power surge? I know surges are the number 1 killer of GPUs/etc. I DO have a UPS for my "good" PCs/desktops, but I don't (dumb) for my HTPC TV and components. That's getting fixed after the holiday weekend regardless now.

edit - Device manager doesn't show an error on the GPU. I tried re installing the drivers twice now, no change/fix/improvement. Now what, any ideas or advice?

Thanks for any help Canucks!

Do you have another GPU to test? If the same problem happens with the other GPU then you could rule out the 3090.

Sound advice. I'd swap out the GPUs and test it out.

Could be a driver issue.

Also, if you are looking to sell that 3090, I'd probably buy it for the VRAM.

Just how many GPU do you have in your basement?

Given the prices of GPU these days, may be worth while to have the card repaired.

Just a few...

Could it be a driver issue you think? I hadn't messed with any new driver installs or anything until after this happened. Cleaned and re installed drivers 2x now.

I do find it odd that the resolution of the bios load/screen whatever has changed, the writing on it is like 4x bigger on the screen now, plus when I enter into the bios after hitting delete/f2, those screens now no longer fit on my TV screen they have such a large resolution. That's never happened before, even when I've updated drivers and during restarts doing that.

If I take another PC up to my office and stick the 3090 in there and it works, what would be the likely culprit then, motherboard, PSU?

I noticed you mention New TV in the beginning of your post did you hook up that office PC with the 3090 to the TV to see if it does the same thing I am not sure of the BSOD, but how is the cable is it seated properly or is the cable old I am just guessed those last few things ?

Yes, this office has my secondary HTPC and a 65" LG OLED in it, mostly for me to watch in here when Mrs Gman insists on watching the typical female BS in our main tv/theater room. I don't have any other monitors in this room, the are all in my gaming room on another floor in the house, and it's a giant PITA to move as I have a ton of HOTAS/HOSAS/Wheels/etc hooked up on several large 60" table arrays.

That all said, something odd is happening. The exact same "black out" which began this happened like 2 minutes ago, and on the TV I got the alert that nvidia sound had returned, and my regular resolution had as well. Checked Afterburner, and everything is normal in terms of clock/mem mhz speeds etc. WTF is going on?! Weird.

Thanks for the help so far, really appreciate it all. Might replace this MB/CPU on this HTPC now, probably time, and I'll get a new GPU with that likely as well, but for now, looks like this is back in business.

The GPU is cursed! You don't want it in your house so send it to me, I'll cover shipping.
