Windows 10: PC crashes unexpectedly after Locking it

Many Users in our Company have been complaining that when they Lock their screen with Windows+L, that after around 5-15 Minutes the Computer just crashes with no error message, i have checked the Event viewer and it proves this, sometimes there are Error Messages, but most times there aren't any... I will attach a Screenshot for these Errors here..This translates to: The System has been shut down unexpectedly at 2:56:27 PM on the 4th Nov 2024The User Locked his PC at 2:48 PMDoes anyone know why this happens? There is no Software issue as we have wiped the PC, we are connected via Docking Stat

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?

 

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

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.
