PC screen losing signal while using computer

[Jest a gamer 27]

My PC screen at the most random times goes black and says that it's going to sleep. I've had it happen to a couple times both while gaming and while web browsing. The tower is still on (fan is spinning and keyboard still lights up), but it remains unresponsive. When the screen goes black, there is no warning, it's just sudden, but else than that it reboots fine. Temperatures are fine (gpu: <70 °C; cpu: < 82°C under load). Is this a serious problem? If so, what is causing it? I also can't replicate it.

I've never had this issue but one of these might be the cause of your problem.

1. It may be a setting in your monitor you can change

2. It might be a bad display cable or it's just not connected well.

3. It might just be that your PC is overheating

1. What setting?

2. I tried playing with the cables with no sucess  . I've even tried replugging it.

3. Its gpu: <70 °C; cpu: < 82°C under load. which doesn't explain why it turned off during web browsing...

When I recently overclocked my Ryzen and started running benchmarks on 3.95GHz from 3.40GHz, my computer would brick and sometimes the screen would go black around 80C. What processor do you have and what is the clock(or overclock)?

 

Edit: Also, whats your voltage if you've overclocked?

Ryzen 5 2600x at stock settings (3800MHz). (I don't mess with OC)

Possibly the power supply taking a dump, but odd it would do that during non load situations.

 

Have you tried a different cable? different monitor? monitor with a different input (laptop or other computer/console), etc?

No, cuz it wouldn't make sense. When it goes black, I have to power down my pc and turn it back on, everything is fine, which is weird. Playing around with the cable, the monitor is fine.

Ok so it sounds like the PC is crashing then, or some component of it at least. There's a program called who crashed that can analyze crash dumps in windows and break it down into plain language. https://www.resplendence.com/whocrashed

Onto the hardware side of things, do you have a different video card to try out? Have you ran any software to stress test the system, a heavy benchmark for video like furmark and prime95 to check cpu/ram? Run both at the same time to stress the power delivery of the PSU to check it also. When did this start and has it been getting more frequent?

I'll try, but benchmarking was never a problem

Seems like everything is fine. It crashed the first time (computer automatically restarted), but now it's running fine...

Solution: RMA my GPU cuz it was defective

Glad you got it sorted!
