I will try unplugging the power supply, But i meant reseting the whole system. I got a reset switch below my power switch.
EDIT:
I unplugged the power supply..Didn't fix it. I don't know..I would check my bios..But i'm not sure what the default setting is suppose to be if it has changed.
Maybe it's just me..But it seems faster now, I been opening pages in my favourites and they seem to open quicker than before

I think it's just me though, I don't think my computer just decided to overclock itself.
