ML150 G3 shuts down without warning

[Bryan M. Wright]

I have a ML150 G3 being used as a test system for drives and tape drives. Recently it has started acting up by shutting down for no reason. Here's what happens:
The video feed goes blank and the mouse and keyboard shut off. The fans stay on as if nothing has happened. It takes several reboots to get the system back up. Every time we try to reboot after the system dies, it gets to the HP splash screen and goes into the same mode as described before, monitor/keyboard/mouse off, fans still running.

I have gone through some of the simple diagnostic steps. I have removed all third party cards, unplugged the extra HD's, and removed all of the extra memory leaving only the 512MB stick. I have also reseated the processor and swapped it out with a known good one.

Looking at the system log through the serial port there is an error that keeps popping up:
Therm-Trip0
Status: Asserted

I didnt find anything with a google search, but I think it was related to the CPU Temp, not a 100% sure on it. I've read a couple of other posts with people having a similar problem, but they didnt have any resolutions posted. Thanks for any information you can give me.

Hi Bryan

Hve you reseated the CPU, and checked that there is enough heatsink compound between the heatsink and the CPU


You could try scraping the old CPU compound off and applying some new compound.

Thanks

I have reseated the processor inside and used rubbing alcohol to remove the old thermal compound. I used the left over thermal grease that came with another ml380 to put the heat sink back on.
I got the full log now and this is the one that keeps popping up:

sensordescription=Therm-Trip0
eventdescription=State Asserted
eventdirection=Assertion

I have recently swapped out processors and heatsinks from systems that are working so far, and it still pops up with the same error. Thanks again.
