Windows 10: I keep repeatedly crashing and my system reliability is at a 1/10.

I have already done 4 runs of Memtest86, no errors in the RAM. I have also completed another RAM tester and, again, no errors. My computer is crashing for a variety of reasons and I have tried reinstalling Windows multiple times. I am very upset.

I can rule out a hardware issue, as when I load into Ubuntu I receive absolutely flawless performance, but seeing as I am a student, I need Windows apps to do my work. Here are a couple bugchecks.

0x0000000000000002, 0xffffec8e79d3a4b0, 0xffffec8e79d3a408, 0x0000000000000000

0x000001c6 0x0000000000000014, 0xffffa486e5092040, 0xfff7a486e5092668, 0x0000000000000000

I am at my wit's end with this.

PC SPECS

Ryzen 7 3700X
Gigabyte B450 Aorus M
32GB Corsair Vengeance RGB Pro @ 3000MHz to test if it was RAM speed issues
850W PSU But that doesn't really matter, because it's a bluescreen.

Show off your system reliability

My reliability failures only list cases when I was testing a new overclock and apps or system crashed during the testing. Other than that, no incidents.

 

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.
