Hi all,
I'm experiencing screen flickering and occasional signal loss after a failed RAM upgrade attempt. The monitor sometimes goes blank for a second before reconnecting. Video of the issue: https://drive.proton.me/urls/DM9KY3Q27R#FOBkbtS5xLAj
There are no other performance issues.
Sequence of Events:
1. Originally had 2x16GB RAM working fine
2. Tried adding another 2×16GB set - worked on first boot only
3. During troubleshooting, accidentally broke a RAM slot hinge when inserting a stick incorrectly
4. Reverted to original RAM configuration, but now experiencing display issues
5. Issues observable starting after login screen, and sometimes even until shutdown
6. Issues most likely remain on consecutive start-up attempts, but after letting the PC rest for a night, they sometimes disappear for many days.
Troubleshooting Done:
- MemTest86+ shows no errors
- Issue temporarily disappeared for days, then returned
- Tried both current and LTS Linux kernels - both now affected
- Confirmed RAM is properly seated
Questions:
1. Could the damaged RAM slot hinge be causing these issues even when not using that slot?
2. What diagnostic steps should I take next to determine if this is a RAM, CPU, motherboard, or graphics issue?
Thanks for any assistance you can provide!

Hi there.
I had a look at your video and this looks like video memory corruption, since you use an integrated GPU that points to defective RAM (or the connection for the DIMMs).
With hinge you mean that plastic lock, that snaps in place when installing the module? It should work without the lock but might have connection problems without enough pushing force.
Also you might have damaged a module, have a look at all the contacts and SMDs and compare the 2 modules. Or you damaged the contacts in the slot, have a good look with bright light and possibly a macro lens/camera to see if they are all straight.
How long did you run memtest? I recommend at least over night or better 24 h.
For the time of testing make sure to disable any RAM, GPU and CPU overclocking (note that many BIOSes overclock your ram even with default settings).

And cables (display cable) have been checked, tested using different cable ?
Of course there are also capacitors on motherboard (vga card), but in these new generation boards caps usually top-notch.
Replacing caps also more difficult, so should be more sure that those are culprit.
