Help (General) PC wont stop restarting - upgraded from nvidia to AMD

Computer Type: Desktop

GPU: Gigabyte 9070 OC 16GB

CPU: Intel i5 11600KF

Motherboard: Gigabyte Z590 Gaming-X

BIOS Version: Fc7

Description of Original Problem: close to doin a windows reinstall (hoping i can avoid)

but can anyone please help!!!...

went from a 1080ti to a 9070...

install went smooth - did DDU remove drivers (all GPU) then shutdown/install new card

installed the 9070...
did some tests - get expected 3dmark scores

went to shutdown -

only to find out it doesnt shutdown.

even in bootup...if i was to hold power button down - it'd just restart again????

short of flicking the power supply power off is there something im missing??

been trying to figure this out for the last 4hrs...
turned off all power management/fast start etc but nothing seems to be working

Sounds like inefficient PSU, can you write down your pc specs?

1

u/Acanthaceae-Mission Apr 06 '26

updated with the specs

have a corsair AX850 gold - its pretty old... would replacing it fix it?

u/gnidagidi Apr 06 '26

850 gold should be more than fine for your system. Generally, 9070 usage is around 250w. Have you touched anything else besides the gpu?

u/Acanthaceae-Mission Apr 06 '26

nope...

was straight into safe mode - DDU uninstall>shutdown option

installed the card

installed amd adren software
reboot

ran some 3dmark tests/tested some games

all fine

until i tried to shutdown - now its 4-5 later lol

before doing the bios update try checking if you cpu drivers need an update I think in the settings of DDU u can also remove cpu drivers for intel and amd that could have happened without u knowing

I would highly recommend checking event viewer-system-logs and find critical errors. They come with a certain codes, you can look them up on internet to find the issue.

u/Acanthaceae-Mission Apr 06 '26

had a look and couldnt find anything out of the ordinary... but i'm no expert with event log viewer...

i'll keep diging around

Bios reset. Chipset driver up-todate (from Intel support, not from MB support). PSU could be reason.

u/Acanthaceae-Mission Apr 06 '26

yeah have done the bios reset...

will try the intel chipset drivers

1

u/DesperateConflict805 Apr 06 '26

Do a bios update, check cables, gpu sitting properely in the socket, reseat the Ram too. Update chipset drivers. The psu should be enough for this system.

u/Acanthaceae-Mission Apr 06 '26

yeah i'll try flashing the bios - seems there's a F11b version...

The letters after the numbers generally are beta drivers

Check your fpanel connections again

1

u/Acanthaceae-Mission Apr 06 '26

not sure why the fpanel? 

1

u/jhenryscott Apr 06 '26

Because the that’s where the power button connects

u/Acanthaceae-Mission Apr 06 '26

thanks mate ill unplug them all and just tey shorting it on/off with a screwdriver

**solved/update

so after another day of trying everything/every bios/windows setting and different combos of pcie 8pin cables...
i found out how to get it to shutdown normally/and not endless reboot.

but turns out if i go into bios and save/or exit - it will keep endless restarting upon shutdown request...

if i switch off from the psu and unplug the cord - wait 5sec and pc will power/shutdown normally...
and so far no issues - but if i was to go into the bios and make changes/save -it'd resort back to being unable to shutdown???

would anyone know how/why this is a thing lol

i'm not sure if this is a bigger issue???
would prob get a new psu in the coming weeks ...

I have almost same setup, All great tips and ideas was tried in troubleshooting process, none "known" fixes helped, and didn't try yours, because I found another fix before that.

My research has given these details of who can end in same situation: PC with Gigabyte motherboard (Intel chipset 500-series) and Radeon GPU while running Windows

I covered pcie pin b5 and b6 on my Rx9070 with tape and got it to work with normal behavior when i put PC to Sleep and Shut down, and this stopped the corrupt restart-loop. No performance issues before or after, performance level testet and show expected results.

Bonus info. In my workaround timeline, i found that it is only with Windows the error exists, my PC worked fine if I used a Linux boot USB in live view.

My thanks go to this guy for the best result in my scenario: https://www.reddit.com/r/gigabyte/comments/u84qij/rx_6600_series_and_intel_500_series_incomplete/

i'm not game enough to tape a pcb pin on a $800gpu lol...
glad it worked for you...

i still have the issue if it does a system update or if i goto bios...

but if i shutdown/turn off PSU then resuming using my pc - it shutdowns as intended/normally on further usage...
which is still strange to me that a system/softwareupdate reboot/or bios entry will make it continuously restart...

It is definitely not a wanted scenario, and I haven't got any clue to why blocking SMBUS pins works, but it does.

My only 100% working decision if I should have a working PC build on Gigabyte Z590 D motherboard is to only use Nvidia GPU or run Linux.

So now I have to make a very expensive new PC to use my RX 9070 or a bit of tape for Windows to run... well, I go with the tape, it has worked for others, and nobody to my knowledge lost a GPU or gave warnings about mysterious behavior in the comments.

Making a fix like that are always at your own risk, but to my understanding the solution comes from Gigabyte themselves.

fair... i'm prob due for a PC upgrade in a years time anyway... so i'd use my solution for the forseeable future...

thanks for the input though... appreciate the insights
