Dell R815 Machine Chk CPU Error

Hello,

I have a Dell R815 machine that will no longer boot properly. Every time I try and power on the machine, I can make it past the Dell splash screen but shortly after the machine will reboot itself. 

The error on the machine's LCD screen is as follows: CPU Machine Chk: Processor sensor, transition to non-recoverable was asserted.

I ran the hardware diagnosis tools there were already installed on the machine and got the error code: 2900:0221. The text that went along with the error code was: System Firmware: Processor sensor (CPU Machine Chk) transition to non-recoverable. 

Any advice to help with this issue would be appreciated.

Thanks,

Casey
