Recently, My Whole PC crashed maybe once a day during playing games like PUBG or GTA V, Or generally under heavy load.

The whole screen freezes, the sound cuts out with a harsh shatter sound and my USB Connected devices (keyboard, mouse, mic) lose power completely.

I've tried upgrading my PSU from 430w to 550w and clearly still an issue.

I removed my overclocked gpu settings, still getting it.

Most likely related to temps but I have no idea other steps to take.


 
Solution
Then start with your RAM if you are 100% sure it is not your PSU.

How many RAM modules? More then 1? Then take all but 1 out and see if the same thing happens. If it does / does not swap to the other module.

If nothing changes, then try a different DIMM slot with 1 module installed. Repeat until every RAM module and every DIMM slot is tested. (Takes time... I know.)


What model?

Motherboard?

Overclocking or not?

I have no idea where to see my fan speeds.

Should I test it with a game like PUBG and see if the fans speed up?

What am I looking for? Should I just send you screenshots?

Do you know why my issue is being caused?
