Intel i5-2500 @3.30ghz very poor benchmark perfomance (1,60Ghz) - Help please!

Hi people.
I am experiencing this problem with my processor.
After a fresh Windows 7 Ultima 64 installation it started to work really slow.
Ive made tests and the results were very bad (I let my benchmark results in the following images).







I also tested it on Ubuntu and the results were the following:

The Windows experience gives me a 5.6 out of 7.9.
The curious thing is the i checked on my BIOS and frecuency is 3,302 GHZ for all the cores.

Any ideas? This is really frustrating ... thanks in advance!
