Question Weird monitor blackout ?

[Vamms]

Hey there,

Recently my PC has been "blacking out". Both of my monitors will go black for either a few seconds or until I restart my PC. Its not a monitor problem as I have now tried about 7 monitors.

About a month ago something happened to my GPU and it was displaying horizontal green lines on my monitor. I sent my PC back under warranty but they couldn't replicate my problem and said there was no issue with the PC or GPU. After receiving it back about a week ago it has been randomly blacking out for a few seconds at a time after I knock my desk. This happens semi randomly, and will happen if I hit my desk hard or just lightly tap it with my finger (not every time but quite frequently). If I'm watching Netflix when it happens Netflix says it has lost connection, Discord will close and certain games will crash but some games will be fine. It has Blue Screened once after a blackout has happened.

I have tried everything I can think of, Replaced monitor cables, reseated my RAM and my GPU, reinstalled my graphics drivers. Every time the blackout happens I check Event Viewer and it will usually show 5 or so errors with the source "nvlddmkm" and it'll give a warning saying "Display driver nvlddmkm stopped responding and has successfully recovered." and after the Blue Screen Event Viewer gave a Critical "Kernel-Power" warning.

Is there anything I can do? I want to send it back to the company I got it from as Its still under its 3 Year Warranty but I'm worried they wont be able to replicate the Issue and I'll be without a PC for 2-3 Weeks for nothing.

Many Thanks.

What is rest of your system including PSU details, by those symptoms it looks like loss of power due to a loose connection.
