Windows 10: Laggy, stutter and glitchy pc after game crash

After playing League of Legends, my PC started lagging, stuttering, and glitching. The game crashed to a black screen, and I had to restart using the case button. While simple tasks like opening Chrome seem fine, running games or programs causes severe slowdowns, with the cursor becoming jumpy and showing the spinning blue ring. Even browser games run poorly at only 20 FPS.Here’s what I’ve noticed:The "Activate Windows" watermark disappeared after the crash.When stuttering happens, audio glitches too.Programs and even the Start menu take a very long time to load.The CPU is consistently running

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?
