I recently installed Ubuntu 12.04 from my windows 7 using wubi. I have all the drivers installed correctly (at least i think) and nothing will completely fail to run. However when I try to run a program and install something at the same time, there are mini freezes every few seconds. It will even stop playing music. I have looked at weather it's from using wubi installer, but nobody else seems to be having this problem. It seems like the cpu is running a lot higher than it should be when using the hard drive.

computer specs:
i5-3450 3.1 GHz (4 cores 4 threads)
8 GB ram
biostar TZ77B mobo
and the hard drive is 500 GB western digital.

note: the windows os is installed on a 60 gb ssd and the ubuntu os is installed on the data hard drive listed above with plenty of space available.
