Question My monitor black-screens and the PC restarts ?

[Creggknows]

I built my computer over 4 months ago everything was great until recently. My monitor would black screen while playing games or just being idle on desktop.
I checked Temps everything is normal nothing high.

What I've tried so far to fix this issue:

• Check my ram sticks one at a time
• Installed a new PSU
• A fresh install of Windows 11

I thought I'd fixed it but after a little while it was back to black-screening and restarting.
I don't know what else to do.

What bios version are you using? There are 11 bios updates from Bios 7C56v10 . MSI MPG B550 GAMING PLUS AMD AM4 DDR4 M.2 USB 3.2 Gen 2 HDMI ATX Gaming Motherboard You can try that if it applies.

Tries the new bios update worked fine for a few days but back to the same old issue. Put in a old gpu. The pc wouldn't boot at all I'm almost sure the motherboard or cpu are giving me issues
