slow CPU speed

[acyphs]

I have Dell OptiPlex 7060 micro with Core i7 8700T.

The CPU speed is stuck at .800 GHz.

It won't budge with any stress test.

I ran the Intel Processor Diagnostic Test and failed.

Here's a snapshot:

Any idea what's going on?

I'd appreciate any input.

I'm also attaching the full report.

Thanks.
