Hi there,

Sometimes my screen just freezes and horizontal green lines appear on screen, the system becomes unresponsive and the computer restarts and I'm struggling to understand why.

I have no graphic card for the moment and rely on Intel's graphics processor UHD 630.

Here's a screenshot

Anybody had something similar and is there a fix for this? Thanks!

Hi there.

Consider uploading your EFI folder for us to check. Remember to redact your serial-numbers from the config.plist first though. :thumbup:

Normally, I would suspect a failing video card but I've never seen an IGPU die...

that would be strange indeed, is there any way to test this? I built this hack less than two months ago so everything is still under warranty...

I would try running Windows and/or Linux for a few days to see if the system exhibits the same behavior. If you don't experience any problems, it should rule out a hardware issue.

Edit:
Check your RAM too. Since IGPU uses system RAM, highly overclocked RAM may cause issues.
