Ntune problem

[collisster]

When I first got my pc I ntuned it and i ran beautifuly, it recently came back from repair and is going quite slow. The repair was on the HDD.
My Spec:
AMD 3700+ 939
Asus a8n sli premium
1gb geil value ram
leadtech winfast pc6800 TDH overclocked (graphics card)
Hiper 580W type R modular PSU
Maxtor 120 gb HDD
All stock fans

I thought I would Ntune my pc again to see if I get a bit more performance out of it,. I found the program and the disclaimer came up, then I recieved this error message :

should I go ahead and ntune or how do I fix it?

Thanks

No, don't overclock before that it sorted. Consult your manual, as it says, or google it. You're steaming towards data-corruption central if you do that!

// EDIT // As a rule of thumb, overclocking in Windows isn't really a brilliant idea. It's much safer to do it in the BIOS.
