...and no, you've not missed the previous 56 tips
But this is a good tip, as I found out today.
There is a very useful CPU tool, called CPUID, that tells you all there is to know about your CPU, your motherboard, your memory etc.
It's available here:
http://www.cpuid.com
Download the latest version and run it - it takes just seconds to analyse your PC and then you can see if it is running OK.
I'd not run this for a while on one of my PC's and I found today I had been UNDERclocking the CPU, by a factor of around 10% - so, instead of running at 3.0 GHz (and with a turbo speed of 3.2 GHz), it was actually set at 2.666 GHz !!
The actual working "speed" of the CPU is set in the BIOS, so you will need to reboot your PC and access the BIOS (usually with the "F2" or the "Del" key, depending on brand).
So, I'm slightly
at having not checked this before.Lesson learned, in my case.
