[SOLVED] Keeps restarting when in games

[Buff infinity]

My pc has been working great the past few days it’s my first build but today it keeps crashing in games and I can’t figure out why
my specs are
Motherboard: tomahawk b450 max
CPU: ryzen 5 3600
Ram: Corsair vengeance rgb pro 2x8gb
GPU: Radeon 5700 xt
Psu: Corsair cpc 750m
Memory: critical p1 1tb m.2
Case: deep cool matrexx 55
Case fans: 5x deep cool RF120m

could my cpu need something other than the stock cooler I have the frames capped at 144

Crashing to desktop, blue screen or restarting?

Restarting

Potential PSU Failure.
Does it happen only when the 5700XT gets on high usage and power draw during gaming?

Yeah it happens when booting up a game and in a game

Alright
If you have anything overclocked, turn it to stock and then test.
If not, you should test the system with a different PSU.
It could be something else causing the problems, for example XMP instability, but this behaviour indicates power draw issues.

I’ll try a different psu tonight but it throws me off that it’s been working fine for 3 days now
