Question PC keeps crashing

[amirerror8041]

Hello, Guys I need help. I have recently upgraded the cpu and ram of my old computer. When doing everyday tasks it performs with no problem at all, but when it comes to playing a game(csgo for instance) the computer keeps freezing and crashing and the screen suddenly goes black(although I still can hear my game sounds) from time to time. Sometimes the PC isn't responsive at all until I restart it, and some times alt+tab works and I can easily end the crashed program in the task manager. I have already tested some of my hardware components (Intel® Processor Diagnostic Tool for the cpu, Windows Memory Diagnostic tool for the Rams and CrystalDiskInfo for the HDD), and haven't seen an error. I have checked the cpu temp as well and it doesn't seem to raise above average. Why does this keep happening? Help me please... I'm using the integrated GPU on my processor.

Motherboard : ASRock h61m-vs3
Cpu : i7 3770
Ram : 6gb ddr3
PSU : 220w
Storage : 500gb 7200rpm HDD

I couldn't find the model on the PSU or their website, but it's built by a company named Sapra and it's from mid 2018 I believe.

Is this a common issue if the PSU is underpowered? I'm getting a little bit worried for the other components back here.
