Constant crashing of games on windows 10

[Decordcane]

I have been having an issue with games constantly crashing to desktop or fatal erroring on me.
I recently upgraded my GPU thinking it was my old one causing the issue but the new one did not help with this at all.
I have noticed that the issue seems to happen allot when I am in a discord call, it will either crash out discord or the game or sometimes both.
I also sometimes get a BSoD error when I keep trying to launch the game to often after the crash.

when I ma playing games it seems to make the CPU go yellow, but it's odd cause these where games that I played not long ago with no problems, just suddenly within the past 2 months this isue has been happining.

These are games I used to play liek a year or so ago on this same PC with the same OS ect... so it should not be crashing like this...
