Hello everyone, I've been having a problem with my PC for a while now.

My PC operates completely fine when I am doing non intensive things on my pc, but once I open a game that demands a little bit more power, after a few minutes, my monitor goes black and says "no signal"

My PC and GPU still runs when this happens, but I can't do anything to make the monitor pick up the signal, except restart my entire pc.

Specs:
3080ti
1000w PSU
ASUS ROG VII Dark Hero Wifi
5900x
32GB Ram

can provide any more info if needed.

I've tried a multitude of things from fresh installing graphics drivers, resetting bios, resetting cmos, basically anything you could think of.

I haven't found a good solution to this problem which I feel like I can't be the only one having. Any help is appreciated.

1000w PSU
1000W is the advertised wattage for the PSU. What is teh make and model of the unit? If it's been in use for a while, please mention the age of the unit.

Did you try working with a higher wattage, reliably built PSU, that's borrowed from a friend or neighbor?

Which PSU brand and model is it?
Did you try the GPU in a different PC?

What temperatures are there while opening games ? CPU and GPU

to have a look what the problem could be:
run userbenchmark.com and post the http link of your result, e.g. https://www.userbenchmark.com/UserRun/28977730

Reset the BIOS by jumper clrCMOS or JBAT or similar (eventually you will have to set the boot priority correctly after that)

check windows integrity
open the command prompt as administrator and type DISM /Online /Cleanup-Image /RestoreHealth

check the memory by running memtest.org usb autoinstaller (bootable USB flash drive)

run the RAM @2133MHz to check if it happens then too

check the hard drive for errors with its manufacturer´s tool
