Hi everyone, new here and hope you can all help.

I have this annoying issue where after I play games my screen loses signal and computer seems to completely crash. So much so pressing the caps lock/number lock keys on my keyboard won't work. I have to hold the power button on my system to get it working again and it works fine till I play and exit a game again. This happens about 10 minutes after exiting a game.

This all started about 6 months ago when I went out one day, put my system to sleep and came home to wake my system up and it would not detect my monitor at all. When this happened I even swapped out HDMI cables and it would not detect the screen. The system suddenly started working again two days later with the original cable but now has these annoying crashes. 6 months ago these crashes would initially happen 10 minutes after booting the system up, almost everyday and then work fine once the initial crash took place.

I did discover that the SSD my OS was installed on was dying and once I found this out I reinstalled Windows on a new healthy SSD. The dying SSD is still in my system but no longer used.

My specs are
Ryzen 5 3600
Gigabyte x570i Pro Wifi
Kingston hyperx fury RAM 2 x 8gb
msi nvidia rtx 2080 super
Corsair 750w PSU
I have 3 SSDs and one HDD in my system
