Hey guys, I have a weird issue with my pc atm:

Sometimes, unpredictably, my monitors turn black and show "no signal"
Im using 3 monitors at the same time.
I can still hear whats going on, such as music, discord messages, people talking etc.
I could be playing games or just browsing the internet, doesnt matter how much stuff Im running. (Tried it with 4x d2r, 5x world of warcraft, forza horizon, 20 tabs with different browsers playing youtube videos on each one and even running 3d mark in the meanwhile)

Sometimes its going fine for 6 days straight, sometimes its blacking out every 10 minutes.
As I said, its unpredictable.

I always have to hard reset my pc, like physically shutting it down and turning it on again.

Temperatures of gpu and cpu are always fine, always within 40-60°C, sorry for the european Units.

I built this pc like 3 years ago, this sh!t has been happening for about 2 months now.

My Setup:
CPU: AMD Ryzen 9 5900X 12x 3.7GHZ
Mainboard: MSI MPG X570 GAMING PRO CARBON WIFI AMD X570 So AM4 Dual
GPU: GeForce RTX 3080 TI GAMING X TRIO
RAM: 2x 16 GB Trident Z Neo DDR4 3600 DIMM


Heres what I alread did:

- updates all drivers, even tried a gpu driver from january this year (downgraded)
- changed cables for all of the monitors

If I was to change any hardware parts, which ones should I go with first?
Probably, gpu, right?

Ive googled and tried almost everything except changing the hardware, maybe some of you guys can help me out :(

Have you tried undervolting your GPU? I'd start there to see if it helps it

maybe a bad psu? undervolting gpu would allow it and fix it ultimately, but i think perhaps with the power draw (4x d2r, etc) on that gpu, perhaps the psu is limiting?

For everyone that's interested, turning off "secure boot" in bios worked :)
