Windows 10: PC crashes without a bluescreen.

Basically, sometimes mostly while watching YouTube however, not when playing games my PC freezes for a second and restarts. Seems like a crash, but in the event viewer there are no entries to be found around the time of the crash. I've tried replacing my PSU, checking memory with memtest86 and testing my GPU and CPU using benchmarks. No problems found in the tests, but yet the crashes still happen and very often. I'm not sure what to do anymore... How do I solve this without just buying a new PC?

Windows 10 crashes in Startup and Autorepair. With Bluescreen Errorcode SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

I was just shutdown PC and is crashed with this Bluescreen Error Code: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED. Then is restarting and crashes with the same Bluescreen Error Code. After 5 times Bluescreen, Automatic Repair. Well you will thinking: "Automatic Repair will fix your PC and then all done". Well thats wrong, is just crashed with the same Bluescreen Error Code.

After 50 times Bluescreen, is still crashes with the same Bluescreen Error Code. Then there is only one way too repair PC.

Didnt work. I want reinstall Windows 10 but, guess what, crash. Then i remove the SSD and is booted up, with Windows 10 Installation DVD, and it worked, then i pluged the SSD in my PC and, oh well, it crashed...

After over 100 times Bluescreen Error, without the Windows 10 DVD. The PC normal booted up. Is doesnt crashes anymore, is just loading... very long... very very long... I guess it was over 30 Minutes. I want force shutdown my PC because, is too long. I booted in Windows 10 DVD andddddddd... Ah not again, is still crashed with the same Bluescreen Error Code.

• Windows 10 installation USB/DVD doesnt work.
  
  • My PC doesnt support USB boot.
    
  • DVD doesnt work, it will just crash.
    
• Windows 10 Automatic Repair doesnt work.
  
• Windows 10 normal Boot doesnt work.
  

• Booting in HDD (not the SSD) (Windows 8.1/10) and it worked, but i want my data .
  
  • The PC will check my Harddisk and repair but without the SSD.
    

 

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?
