Too start my pc specs are:
cpu: Ryzen 2700x
Gpu: Rx 5700 xt
Mobo: X470 gaming plus
Ram: corsair vengence rgb 16gb 3200mhz
psu: TX 650m corsair
cpu cooler: Be quiet pro with 2 fans
wd green 240gb SSD
SSHD: seagate 1tb
With this PC multiple issues and the first one is I'm having random screen flickers where sometimes it will flicker some parts of my first monitor to my second one, i believe i have fixed this but it's only been 1 day and it may come back. The second one is after coming out of a game or sometimes in a game my pc will crash and start displaying a green screen and it will start making a noise (through my headphones) and it won't let me do anything apart from turn my pc off from the psu. The last issue is similar to the seond one which sometimes during games my pc will stop displaying anything, and anything connect through usb will stop working (lights on keyboard turn off) with this i'm again having to turn off my pc though the psu. Ihave tried updating the bios and completely resetting my pc however i'm still getting the same problems, i have checked my temps as well and it doesn't seem to be because of over heating. Can someone please help because i'm completely lost.
