M90P (328B5G) anomalous and autonomous system restart [ Edited ]

[redcell]

I have a ThinkCentre M90P (328B5G) with a strange problem: it restarts himself sometimes...

The machine is a Windows 7 Professional x64, for now without any software it has installed only the antivirus NOD32 v 4.2

because the machin is still in a "test state".

Is there anyone that could have solved the same problem on the same machine?

Hi

Thanks for your Post

To identify the exact issue , Please try the following

1.  Clean the memory Modules and reinstall the same

2. Check if under event viewer any error is recorded after the restart

3. Keep the system in Bios mode for some time and check if it restarts under Bios mode also

Cheers!!!

I've found the problem: it's a problem connected with bios version: upgrading bios to newer version.

I've found that it's necessary to upgrade BIOS version at least at 5JKT55A or higher.

After having updated BIOS the problem definitevly desappeared; it seems it's a known bug.

I've found solution to the problem here:
