2008 Mac Pro Running Slow

[TXTornados]

I have a 2008 Mac Pro 2.8GHz and it has been running slow, so I used TechTool Pro 8 and it identified during the Sensors Test that the Voltage on CPU-A Core failed with a value of 0.07V.

Does anyone know what could be the cause and how I can remedy it?

Thanks.

Run Apple's test by rebooting and holding the "D" key when you hear the chime. http://www.macissues.com/2014/03/21/how-to-run-and-interpret-apples-hardware-tests-on-your-mac/

Considering that the minimum voltage for most Xeons is 1.33 V it looks like that chip is fried. Time for a new CPU.

Please define slow? What kind of hardware is install? Screen capture activity monitor and the tech tool page. Usually if a CPU goes down/removed, the mac will not post. No Chime, No Boot up. We need additional information.
