Windows 10: System Crashing

My laptop keeps rebooting every time I begin to use Adobe Premier Rush 1.5. This has been happening ever since I got the laptop but when in different apps before. I just had my motherboard replaced on it. Since it completely crashed earlier this year. I got it fixed finally last week and it has not allowed me to fully finish a project in Adobe without shutting down at least once. When I go into the reliability monitor it shows me I have 15 critical events. I need help getting this fixed! I am about to get rid of this darned thing at this point!

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.

 

Help! New system keeps crashing

It's runing through them now. It's a step forward, as the problem was the system crashing as soon as I pressed the key to boot from the disk, it crashed before I even got to install it. When it's done, I'll burn another copy, see if that works.
