Question HELPP! PC randomly restarting while playing game.

[CLattice]

Prebuilt Specs-
CPU: i7-11700KF
Mobo: ASUS TUF Gaming Z590 Plus
GPU: Gigabyte RTX3070
RAM: TridentZ 3200MHz (2x8Gb)
PSU: 750w 80+ Gold rated (unsure what make/model as it came in the PC)
Cooler: BeQuiet! Dark Rock Pro 4
Windows Version: Win10 Ver. 22H2, build 19045.5371

Help!

My pre-built PC has had quiet the bumpy road, from having to change the cooler from a water cooler (as cpu temp would be 80C+), then changing the cpu glue, but a problem that it has always done is the random restarting mid video game. The game is not always one of high demand and it isn't everyday or anything. I tend to ignore it when it would happen because it would not be multiple times a day. However, yesterday all of a sudden it short circuited (turn on and off rapidly) and I had to remove the battery from the mother board to do the Bios Restart Launch. I have always thought it was a voltage issue but there are instances where I am not sure anymore. This has been happening for a good 3 years but it never became such a consistant problem until yesterday/today.

I am hoping it works well tomorrow when I turn on the PC again as it tends to "pick and choose" what days it wants to act up. I would appreciate any advice and recommendations for my settings in both UEFI BIOS and Windows 10 Settings for optimized gaming all while making sure my PC does not crash.

Thank you!

Welcome to the forums, newcomer!

What BIOS version are you on for your motherboard?

PSU: 750w 80+ Gold rated (unsure what make/model as it came in the PC)
You might want to take off the sides panels of your case and then see what the stickered sides of the PSU says about it's make and model. If you're unsure of what you're looking at, pass on images for the stickered sides. You will need to host your images on a site akin to Imgur. Then pass on a link here for us to see.

A system will reboot for one of two reason when taxed. Either you're having:
1| an overheating issue
or
2| you PSU is incapable of delivering necessary power when taxed

This has been happening for a good 3 years
and how old is your PSU?

What games are we talking about? Where did you source the installers for the game(s)? What sort of temps do you see when the system reboots? You forgot to mention the make and model of your case.
