HP ProLiant turns off after attempting to resolve NMI Channel Check / IOCHK Hardware Malfunction

[corbimos]

Hello!

I was having an issue that was described perfectly in quite a few threads. HP actually posted an advisory and fix on this issue. 

https://h20566.www2.hpe.com/hpsc/doc/public/display?sp4ts.oid=7796454&docId=emr_na-c04872177&docLocale=en_US

But now after using their fix, the machine just randomly shuts down. No Errors, no warning, and no more blue screen. 

Does anyone know where i can start at trying to figure out the real issue? The machine boots fine and turns off after about an hour.

Thanks a ton!
