[SOLVED] PC crashing with pixelated screen. Shutting down and stuck in BIOS ?

[Gigahurst]

Hi everyone!

I have a 4/5 months old PC I built that likes to pixelate and go black, boot into bios and won’t let me past it until I turn it off & on again.
This seems to only happen when gaming.

CPU: AMD Ryzen 5600x
Motherboard: MPG B550 Gaming Edge Wifi
Ram: Crucial Ballistix 3600MHz (2 x 8gb)
SSD/HDD 1: Crucial P5 1TB (CT1000P5SSD8)
SSD/HDD 2: Lexar Professional NM700 M.2 256gb
GPU: NVIDIA 3080 FE
PSU: NZXT C750 80+ Gold Certified
Chassis: Corsair 4000D
OS: Windows 10 Pro
Monitor: Samsung Odyssey G75
BIOS version: E7C91AMS.150
Windows version: 10.0.19044 Build 19044

Also in event viewer I get ‘event 41, kernel power’ after it crashes.

(Will test temps and post in comments)

Any suggestions will be appreciated.

Event 41 is just a generic unexpected shutdown, most commonly caused by the PSU struggling to provide sufficiently stable voltages.

The RTX3070 and up are known to give many PSUs a hard time.

Is 750W to small for a 3080 in your opinion? If the PSU struggled to provide the voltage would the screen go like in the images?.

750W should be enough for quantity. The problem usually lies with transient response - how well the PSU handles the combined CPU+GPU load shifting by 20-40A on the 12V rail on a sub-1ms time scale.

Wonky power can cause all sorts of issues. It could also be a defective GPU - plenty of RTX cards had the "space invaders" crash early on.

Update - When the PC shuts down the VGA light comes on then changes to the Boot light. (Also notice the graphics card lit up logo turns off for a second, not sure if that is because the whole system has turned on and off).
