Hello guys. I am using hp elitebook 8540p . It was all good aince years. But suddenly it starts freezing until i turnit off through the power button. And sometimes it starts working automatically. On windows, sometimes the screen turns black for just a second and comes back and sometimes i see some colours for a second. 

I already tried new windows, updated everything, all the drivers are working fine, replaced a harddrive, ram, changed thermal paste. 

I used thanos os for gaming purpose on this device and there too the screen freezes. 

Sometimes my pc gives me Dcp watchdog violation error, Sometimes it stucks without any error. I got mad because of this issue.
