Hi- I have the processor as shown above. It is a dual core TK-53 1.70 GHz. I want to upgrade my personal computer from Windows Vista to Windows 7. I ran a check through Microsoft Windows 7 Upgrade Advisor several times in the past. What it is showing me is that since Feb., 2016 until yesterday, the processor speed has dropped from 1.70 GhZ to 800 MHz. My questions are- is this something that I need to check into further & is the processor about to "burn out"? I do know that the CPU has been running hot & I believe has overheated in the past. Is there another way I could check the speed as far as getting a second opinion to be sure it really is that slow?
