I'm having some weird CPU issues.

The processor in my computer is a 2100+xp athlon processor (1.73mhz) - but for some

odd reason, starting from today (i think) - its being reported as being 1500+ and

1.23mhz

This can be seen at startup, in system information - everywhere.

Why is this?

Whats happened to the processor? How do i fix it so that it shows its original

speed - and also, is this new lower figure causing for it to work at this lower

speed?

The only thing i did today was install a new scanner - could the drivers be giving

problems? If so, what do i do, what do i uninstall.
I tried uninstalling it via device manager (is that how you do it?) - didn't work,

so i tried doing a system restore so that it goes back 3 days, that didn't work, so

i restored it the settings back.

I have no clue, so any help would be appreciated to get my 1.73mhz back.

Many thanks in advance
