Is my grapic card demaged? (vega 64 1day old)

[Ryzeen]

Hi guys!

Just build my first computer.

And the first thing i did was to overclock (and lowered voltages)
to my SAPPHIRE RADEON NITRO+ RX VEGA 64.

Aaaand my computer froze. Thats what soppose to happend under a overclock for what I know.

then I had hard time to restart.
My screens was flickering and it seems to reboot every 0.5 sec..
But I menage to get it to work again.

But now my background seems to dissapear in squares xD
here is picture of it

My background seems to appear after 10-30 minutes or so.
I have restored and uninstalled afterburner.

Does this have anything to do with overclocking my GPU?
Or just windows.
How can i fix this issue?

Thanks guys, And im sad that this has to be my first thread!

Do a clean driver install. Use DDU in safe mode to uninstall the old drivers, reboot and install current drivers. Reboot again and see what happens. Failing that, go here https://www.techpowerup.com/vgabios...X+Vega+64&interface=&memType=&memSize=&since= and download the BIOS at the bottom of the list and reflash your card, FOLLOWING ALL INSTRUCTIONS!
Close all other applications, etc..

The above, of course, after you clear CMOS on your motherboard per the manual.

It is from overclocking the GPU. Return GPU settings to stock.

So you both overclocked and lowered the voltages on the GPU? Usually people either raise both or lower both. Going in different directions is as recipe for instability.
