Random crashes since Windows 1803

[geollum]

Hi guys, I hope some can help me with the problems I'm having the last couple of weeks.

 

Since my system updated to 1803 I'm getting random freezes and reboots.

If they occur, most often while playing games, sometimes while idling. But other times they don't occur at all. There is no real specific pattern.

Yesterday I decided to completely wipe my system and directly installed a fresh copy of Windows 10 1809, but the problem still exists.

Event Viewer doesn't give any info, just "Critical Kernel-Power 41" with BugcheckCode 0.

There are no bluescreens or anything else that could indicate any problems.

 

My specs:

i7-2600K

Asrock Z77 Pro4

2x 4GB 1600MHz + 1x 8GB 1600MHz
GTX 970

be quiet 580W

 

This configuration was running fine for over 4 years (overall system almost 8 years already), and on the day 1803 gets installed I'm starting to have those problems. That would be too much of a coincidence that some part started to act faulty on the same day a windows update is installed.

 

I tried installing the latest driver in case of some compatibility issues, didn't help.

I suspected it to be some Meltdown or Spectre fix that is bundled since 1803, and tried disabling them with InSpectre but also to no avail.

 

Does anyone have other clues as to what might be causing this problem?
