I know this because it only displays my card as 1.73 GHz on the can you run it lab and my computer properties says this:

Genuine Intel(R) CPU

T2250 @ 1.73GHz

1.73 GHz, 2.00 GB of RAM

There is no such thing as a driver for your CPU.

The Intel T2250 CPU has a 1.73 GHz clock speed, so there is nothing wrong with your PC:
