Monitor loses signal ONLY when gaming

[33canim]

I’ve had this gaming PC for about a month, it runs perfectly fine when I am watching a movie or idle but my monitor loses signal 5-10mins of playing any game and I can’t find a permanent fix..

I have a rtx 3080ti with a corsair 850W RMx and 1x32gb ram (💀), my monitor is LG UltraGear 27GP950 im not sure if that matters as it works perfectly fine with my ps5. however I have tested 3 separate games on PC and all of them have lost signal, usually I listen to music on my PC while I play and when my monitor loses signal I can still hear my music but the game audio completely stops? im forced to reboot the computer manually each time, I have tried switching hdmi cables to purchasing DP cables (yes its plugged into the gpu) yet the issue still persists, ive done driver updates and even rebooted my pc still nothing,… im at a point where I want to fully get a refund for the PC just to avoid the hassle because I can’t find a single solution and it’s frustrating.

I am planning to request an RMA to replace the gpu as I suspect its the one failing but im not sure if it could be something else..😭

Note: sometimes when I boot up my computer I hear one long beep and 3 short beeps and receive no signal whatsoever

Can you post your full spec please from your order?

I would personally suggest contacting PCSpecialist and issuing an RMA to explain what you've been experiencing.

I had a similar problem with an EVGA RTX 3080 Ti. The PC ran light/older games just fine, but any newer game or stress test and it would either lose signal, artifact, flicker, or BSOD. Eventually (and I mean less than a month later), the PC would fail to post. I sent the PC back for an RMA and it turned out the GPU was faulty. After having it replaced, I've had zero issues since.

I'm not 100% able to guarantee the GPU is the issue, but the issues you've mentioned + troubleshooting steps you've made would strongly indicate that this is the case.
