We have a number of HP EliteDesk workstations of varying models (8300, 800 G1) in our organization, some of which started exhibiting strange behavior over the past few months. Checking the Intel AMT event logs we see every 2-3 minutes the following error message being logged:
Operating system lockup or power interrupt.
The machines in question are all running under Windows 8.1.
Symptoms include system slowdown, occasional system lockups which in time become more frequent, sometimes the machines fail to boot up and just hang before the user is able to enter their login credentials (blank screen with dark blue background - not BSOD).
We have updated the BIOS on all affected machine which was a recommendation from Intel when these errors start frequently appearing in the AMT event log. It did not help - the error still keeps being logged every 2-3 minutes or so.
Also, we've updated / reinstalled device drivers, did a Windows Refresh, ran a malware scan...
We have been in contact with HP support regarding the first machine to exhibit these problems and they were unable to resolve the issues (MB, memory, processor, HDD all been replaced; finally, the entire machine was replaced with a brand new one which for now is working OK).
Now two more of our affected HP machines are starting to exhibit system lockups as well.
Question:
Since Google searches did not return much useful information, and we've tried everything we could think of to resolve these issues, we'd like to ask if anybody else experienced similar issues? How did they resolve them? Any troubleshooting suggestions, tips?
