PC suddenly blackout and restarting without warning

Hello,

After updating my windows 10 which is automatically, my pc will suddenly got blackout and restarting without any warning. of which after logging in to windows it will blackout and restart after 3-5 minutes no matter what we do either browsing or gaming.

It will always happens when opening the pc for the first time, but the windows will not restarting again as long as we keep it on...

Unless if we shut it down, and turn it on again and it will blackout and restart again. Any help please?

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?

 

Blackout while installing windows ?

Just clean install my computer yesterday and right in the Finishing Up step after Installing features and updates step done, there is blackout and my computer turn off right in the Finishing up step and back on after 2 minutes and windows continue the installation as usual without problem, until windows successfully installed on my computer. I've been using my computer for couple of hours and nothing problem, everything just fine. But i am worried about the blackout during the installation can cause damage which will happen later because maybe some file not yet installed because blackout.
