Help! lost all USB ports and ps2 mouse :(

[lprulez]

Some days ago i overclocked trough the bios (cpu was @ 1.65V and 220 fsb) and after increased it to 222fsb using the nvidia system utility. After doing this my mouse (microsoft wireless optical) went mad and doesn't work well at all. When it goes in the desired direction it kind of 'jumps' from one place to another and at other times it goes its own way. Only my keyboard works and all usb peripherals are 'dead'. Formatting did not affect anything and neither loading the default settings worked. Any suggestions plz??? A while ago a user had a similar problem but didn't say how he solved it See Last Post
