Question My monitors keep showing "no signal" when I play games ?

[BigKobi]

Whenever I try to game, I would start the game up and then throughout lets say loading screen or even lobby's depending on what game I'm playing, the screens turn off, whenever i try to press my keyboard and mouse they don't wake up, i also could hear audio when this happens though as I can hear YouTube in the background and even some games.

The game I tried were apex, Fortnite, Rust, Six Siege, Sons of the Forest, those sort of games and if I tried like a low end pc game like Roblox or Minecraft its fine, It always just depends on the game I'm running

Whenever the graphics are on the higher end of graphics my monitors turn off.

I have a RTX 2060 with a i5-9600K I tried changing graphics cards and I've had the same issue, I tried changing displays by only using one, and even trying my TV, still didn't work, I tried changing the power cable for the displays as i have splitter and have two monitors, but still to no avail, I tried updating drivers and it didn't work, and I'm stuck at a road block with no idea what's wrong with this computer, I have the slightest feeling it might be my PSU being faulty or old but I'm not too sure

Full system hardware:
H310M H LGA1151
I5-9600K
Corsiar LPX 16gb ddr4 3600
RTX 2060 from gigabyte
Ace ATX Switching Power Supply model: A-850BR

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

Look in Reliabilty History and Event Viewer for error codes etc. that occurred just before or at the time the screens turn off.

Increasing numbers of errors and varying errors make the PSU a likely suspect.

More information needed.

I checked reliability history and it says that at the time it happened it says windows hardware error as critical and I look further and its to do with the LiveKernelEvent, I also checked event viewer but I couldn't find anything happening at the certain time when the screens wouldn't appear

But while I was writing this last night, my browser closed and then everything froze, my screens then went black but I could still see the cursor and I could tab in and out of the event viewer and the reliability history but they wouldn't appear on the screen, then my computer got blue screen of death, so it done that and then it kept booting into the bios every time I tried to save and exit the bios, so I just cut the power and I tried to boot up again and it wouldn't, but today when I tried flicking the PSU off and on again it booted
