Question PC keeps rebooting with certain games

[04niceck]

Hi,

I'm having a problem with my computer and hoping someone here could help me. Basically when I am playing certain games, particularly LoL and FF14, my computer will instantly cut off and then restart itself. I am not sure why it is these games particularly but more graphically intense games I have played do not cause my PC to shut off. It's happening every 20-30 minutes now and I need a solution. After googling the problem the most common suggestion is an issue with the PSU. I have cleaned the PC with a can of compressed air and made sure all the fans are dust free. I checked my PSU and it is 550W which is more than sufficient for a GTX 1080 from the recommendations I googled online. I'm not sure what else to do, I can't really afford to buy a new PSU unless I can be sure that's the issue. Any suggestions would be greatly appreciated. I will paste my specs below, apologies if I have missed anything, i'm not tech savvy at all.

My specs are:

brand and model of this 550w psu?

Its the Corsair CP-9020097-UK VS Series ATX/EPS 80 PLUS Power Supply Unit, 550 W

Have you checked the temperature of the GPU and CPU? Play the game for just 15 minutes and quit it, then check the temperature under Task Manager

Depending on how intensive the game is, it will heat up components eventually

A VS550. Why do you use a low end PSU for a gaming rig. Take a look at the PSU Tierlist and you'll find out that Corsair VS is recommanded for cheap igpu systems only.

So I ended up buying a new PSU - Corsair CX750F RGB, 80 PLUS Bronze Fully Modular ATX Power Supply. My PC is still rebooting itself even with the games on their lowest setting, What else could it be if not the PSU?

Memory. Try running each stick on its own.

I have done a Memtest86 to check the RAM for any faults and there were no errors. I also reinstalled the games on a nvme M.2 I recently purchased and the issue still persists.

Brand and model motherboard?
Motherboard BIOS up to date?

Regardless of Memtest, have you tested with each stick on its own?

The motherboard is an ASUS PRIME Z730-P. I have never updated the BIOS since i've had it.

I can try this. The fact that its only an issue with one game I play (League of Legends) makes me think its not a hardware issue now. Other more intensive games do not cause this issue.

Maybe reinstalling windows? I have updated all my drivers and all the windows updates.

Work to be done!
