5080 Issues

[Cooners]

Wonder if anyone could help.
I installed my 5080 yesterday and I have some isssues that I could do with some help sorting.
First the PC now won't shut down, it just gets stuck with the keyboard, mouse and screens off but the RGB and fans going (The fans get faster and louder)
Second all three monitors are working fine but if I plug in the HDMI for the TV and the TV isn't on the monitors turn on an off in a random pattern, sometimes one goes off, sometimes two and sometimes all three. They quickly come back on again but the only solution is to unplug the HDMI cable from the PC or turn the TV on as this then works fine.
And lastly if I run the auto tune it gets stuck with a cap of 1920mhz and won't go over it. I only noticed this when I saw my 3D mark score was 2000 below average for this GPU and then after resetting the auto tune trying to sort the above issues I found it working properly and I had a much higher score and gained over 20FPS!!!!

Is all this related or am I looking at three seprate issues? I'm tempted to just reinstall windows as I haven't done it in years, had an AMD card before and have everything backed up to the cloud anyway.

1) Did you use DDU to uninstall the AMD driver? If not, consider uninstalling (all) GPU drivers again.
2) Bios of motherboard may not like the RTX 5080, consider updating the bios, so it talks nicely to the new shiny GPU.
3) You do not mention what your power supply. If you have an old power supply or a PSU below say 550 watts, that may also be an issue.
4) HDMI issue, you should swap to another HDMI cable. Suggest HDMI 2.1 cable. A quality one. Also swap HDMI slot on GPU.
5) Check event viewer in Windows, see if that is reporting issues?

When I get a new GPU I stress test it, I use Furmark. If you get artefacts on the test, you may have a faulty GPU core, or GPU VRAM. Then RMA it asap.

Hi I've got a brand new 850W Corsair RMx PSU as my 650W would be cutting it fine.
I didn't uninstall the drive first as I was planning on taking the old card out and then uninstalling the driver but I forgot that the AMD CPU doesn't have ingrates graphics (I've been messing about with Intel machines and lot lately). However this started as soon as I unistalled the AMD drivers (not sure what would have happened if I'd rebooted before that though.
I've used DDU in safe mode to uninstall both AMD and Nvidea drivers now but the PC is still freezing on reboot.
Bios was updated a few months ago and is still on the latest version when I check the product page.
I've not found anything in the event viewer just the critical error when I have to hard reset it everytime.
It reboots fine in safe mode and also in normal mode if I quickly restart it in the first few seconds of logging in which makes me feel theres a faulty service/driver but I can't for the life of me work out what.

Check the graphics card is seated correctly, maybe re-seat it
Latest chipset drivers installed?
Tried it with just 1 monitor connected?

Yes I only plugged one monitor in at first and it did the same thing.
I'll check the chipset drivers, good call
I'll reseat the GPU tomorrow if all else fails (I tried to take it out but the things so big I can't push the release tab on the PCIE slot!!!

So I went nuclear in the end. Was wasting too much time mucking about.
So far so good, it's rebooting fine and I'm rebooting after everything I install for a second in case something specific tripped it up but it's sorted now
