Windows 10: PC crashing

I recently built my computer about a month or two ago and I have been noticing some issues. Sometimes when I boot it up on launch it freezes and doesn't respond. This usually happens on the default windows lock screen. It happens so my monitors refresh rate drops to zero and my RGB on my keyboard stops moving and stays static. Other times this happens is when I could be playing Tom Clancy's Rainbow Six Siege. My fans and RGB inside my case along with my ram RGB stay the same speed and keep functioning like normal but everything is frozen the only thing overclocked in my system is my GPU (Ryzen 7 2700x) at its max 4.3 boost. But the CPU stays at a nice 30-35- degrees Celcius because I have an AIO liquid cooler can someone help me solve this issue.

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?

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.
