Question Faulty PSU or MoBo?

[apollote]

I have been getting lots of freezes lately where I cannot move my cursor or do anything. I have to manually restart my computer by switching it on and off. These freezes happen while browsing the web, watching YouTube, chatting on Discord, playing low intensive games. Around 3-10 freezes a day. It is getting annoying. I have considered this a PSU problem, but I am not sure if it could also be a MoBo problem. Note that my system is only 3 months old, and ever since I built it I could never play a graphics intensive game because I would always get a BSoD.

I know that it is not my GPU, CPU, or RAM. I also do not have temperature problems.

The reason why I am asking is because I am about to buy a new PSU, but I do not want to buy it, only to realize that it was not the problem.

Anything helps and is much appreciated.
