A couple weeks ago, my CPU underclocked itself.. I dont remember the exact numbers, but a couple days later, it underclocked again. It now runs at 1.16Ghz, and peaks at 59% capacity in task manager. On the BIOS menu, it shows that it is a 2.0Ghz Processor, and that it is running at 1.20Ghz. Of course the first thing I checked was speedstep, and it was never enabled. There have been no temperature issues, it runs at about 41C idle, and 60C under peak load (during a processor performance test). I know these are a bit high, but still well within range.
This is for a Dell Latitude D830, I contacted support, just spent 45 minutes on the phone with a very rude rep.. They were not helpful at all. They had me run a sort of diagnostic, it checked the memory.. Tests came out fine. They told me they couldn't help me further because i'm not the original owner.
I'm quite certain that this must be caused by some sort of failure in the CPU, that a transistor, or a whole circuit went out.. It's an old computer.. It runs stable, never have any problems other than trying to run 2014 programs on a 1.16Ghz processor at 59% capacity...
If it is just that it's old and dying, then fine, I'll accept that, but if there is a solution, I certainly would like to figure this out. I have a spare CPU of the right socket, but it has a few bent pins, and is only a 1.8Ghz, so I would prefer to fix this one rather than deal with the other.
Any insight, even the bad news is greatly appreciated, I am just really confused why a CPU would do this.
Thank you everyone, for reading, and for those who reply.

Did you scan for any virus ? I had a virus that uses my processor %100 for all the time and I removed it very easily so you had better scan it if you didn't

It does not have any viruses, the same hard drive works fine on my other computer. Also you can see that there is a problem in the BIOS menu, before windows is even started, before the hard drive is even being used.
