I have my friend's PSU, the last time we tried the motherboard didn't even powered up for some reason. I can try it again tonight though. Is there any other way to confirm the PSU has gone bad?

Did that from the day I installed windows. Should I try to turn it on and off again ?

Yes, its 19.1.1.

I am having trouble with my recently built PC(Check specs/component list below). The system works normally while not gaming. (had high idle CPU temps but now it sits at 35-40C at idle, which is normal in India) But when I play moderately demanding games like CS:GO/Ruiner/Apex Legends it will run smoothly (no performance issue) but it will crash after 15-20 minutes, no warning or freezes, straight to black. After that it won't boot up until I turn off the PSU and wait for 10-15 seconds. Even if I leave the PC for hours, I have to reset the PSU to boot it up again. More information: Even though the idle temps are pretty reasonable now the CPU temps while gaming are a bit on the higher side (hovers around 68C, sometimes jumps till 80C) The RAM heats up(not sure if this happens always) a LOT when playing Apex Legends (90C), I am using the DOCP profile for the RAM to run it at 3200 Mhz and 1.35V (this was set by the profile), everything else on the BIOS is default I am using Kraken M22 as the cooler for my CPU The system NEVER crashed while normal operation. Also never crashed while playing DotA/LoL. Event Viewer always has this entry before it crashes. (Event ID: 6).
