Windows 10: PC Stuttering when gaming and crashing

Hello,I recently encountered an issue where if I start up a game, my frames will drop and after afew seconds my pc will crash into a black screen. I first encountered this issue 2 days ago as it will occasionally stutter while I'm gaming however now even launching a game will crash my PC. I have run Malwarebyte which didn't encounter anything and updated my GPU drivers via the Nvidia app to no avail. I also monitored my GPU, CPU and RAM usage as I previously had a similar issue but this time they are all normal and seem to not have any abnormalities. I am still experiencing this issue however

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
