Question PUBG Won't Start - Causes System Reboot

[MrN1ce9uy]

PUBG on Windows 11 seems to be broken. It has been causing my PC to hard reboot as soon as the intro video finishes and the main menu is loading. You can find other people talking about this online with various hardware configurations (AMD and Nvidia) and it seems to have to do with their anticheat software?? How that could possible cause the whole PC to reboot is beside me. This hard reboot happened to me earlier this year, then it quit, now it's doing it again. I haven't found a solution yet, so I'm hoping someone here can help.

How old is the PSU in your build? BIOS version for your motherboard at this moment of time? Also, might want to try and resort to an aircooler to rule out a faulty//failing AIO.

PSU is from 2018. However, +5V shows low at 4.4 and 4.5V. Do you think this could be causing reboots?
BIOS has been updated this year.
I just updated it with last month's BIOS release.
I also tested with Prime95 and the CPU cooler seems to be working normally.
I even deleted the game files and re-installed PUBG. Still causing hard reboots.

Heaven Benchmark runs fine. Prime95 runs fine. 3DMark runs fine. It seems to be a problem with PUBG.

Now it's hard rebooting randomly while browsing the forums here. Not just the game. I'm going to try a different power supply I have installed in a different computer. I'm trying to avoid the other power supply though, because it is powering a RAID10 array. I'll see if I can disconnect it without disconnecting the SATA (data) cables.

Solved. The PSU was the problem. Changed it out with Seasonic Prime Gold 1200W and PUBG started just fine. +5V rail is now at 4.9V. I can't believe I've spent a year trying to figure out why my system has been restarting. I'm glad this is finally resolved.
