Blackscreen with GPU fans at max speed

Question

Sympton:

• During some games, after 2-20 Minutes a black screen appears
• CS2, CS:GO, Anno 1800 suffer from blackscreen
• Did not get a single black screen playing hours of COD
• Sound is still playing in background when black screen appears
• GPU fans turn instantly to full speed

What did I try to solve the problem?

• Clean reinstall of Windows 11
• Installed all necessary drivers from MSI (which is my mainboards manufacturer)
• Installed current NVIDIA driver
• Replaced 850W PSU with brand new 1000W PSU
• Checked Windows Event Viewer for any hints, none found
• Executed a mem test without any errors (https://www.memtest86.com/)

My specs:

• 12GB MSI GeForce RTX 3080 VENTUS 3X PLUS OC LHR GDDR6X 3xDP 1.4a 1xHDMI 2.1
• 11th Gen Intel(R) Core(TM) i7-11700K @ 3.60GHz (16 CPUs), ~3.6GHz
• Windows 11 Home 64-bit (10.0, Build 22621) (22621.ni_release.220506-1250)
• MSI B560M Pro-VDH Wifi (B560,S1200,mATX,Intel) (7D18-001R)
• be quiet! Straight Power 11 Platinum (1000 W)

Do you have any ideas on:

• what could be the reason for the black screen?
• what can I do to further troubleshoot the problem?

Thank you!

Answer 1

When you try replicate the black screen, have a temperature monitor on to see what is happening - my first thought was the power supply not providing enough power but you said you already replaced that.

If the temperature is normal - The only other thing I can think of is the driver crashing - try a few version of the driver too. (DDU the current one).

Something else to try is to use a try the GPU in a different PC to rule out any hardware.

The last resort I would even consider is reflashing the bios on the GPU - but i would not even consider this without consulting with the graphics card manufacturer first.
