Windows 10: Crash/Restart - No BSOD

Hello, I got a relatively decent PC. Don't have issues that often, but with certain games -recently- my PC crashes and restarts without going into BSOD. I kept an eye on thermals and they seem fine. I also checked on my drivers and made sure they were up to date. I will attach the minidump logs for three similar incidents, any help is truly appreciated!Thank you in advance.Please find the logs here.

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?

 

Random restarts

when you start the computer up press F8 repeatedly until you get a list of how to start windows, choose do not automatically restart on system failure. if your getting bsod's list what your getting here so we can further help you. IF the system is not getting bsod's and still restarting as you say then i would look into getting a line conditioner for your computer as you might be having power issues.

 

Big Problem! Start Button wont work, and Desktop Icons gone!

Suggests BSOD. Disable automatic restarting on system failure.
