Windows 10: Windows freezes or crashes after launching certain games or programs

Purchased a prebuilt computer from Cyberpower back in October and have had this issue since. When I open games like Rust, New World, or League of Legendsoccasionally it will either A Freeze/Crash after a few minutes forcing me to turn the power off via power supplyB Prevent me from opening any new applications, or start any new actions on the computer Ex. If I have chrome closed I cannot open itI cannot reinstall my windows because it does not let me, and I cannot download windows onto a boot drive to install it because it does not allow me, I understand the problem is likely my windows

all games crash!

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.

 

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?

 

PC Freezes for 1-2 seconds when launching certain programs

The PC would freeze for a few seconds when I open certain programs the first time after waking the PC from sleep. It would not freeze if I open the program again after the first time, until I sleep the PC again. Programs that would freeze are e.g. MPC, Potplayer, etc.
