Pc hangs randomly

[Jupsik]

So basically windows will hang randomly, usually when I e.g. try to access some website. What will happen is that it won't load and will gradually lock up. The mouse and keyboard remain responsive and if I have a game open (lets say diablo 3) then it I can continue to play it until the rest of the pc unhangs itself. I can also switch between programs, but if i do it more than 1-2 times, those will lock up as well. One thing that i've noticed is that my C drive activity goes to 0 for the duration of the hang (other hard drives have continued working), due to which I'm suspecting that its the C drive that's being special. So what do you guys think? Should i go and get a new hard drive?

Go to the manufactures website and down lode  the the tools to run a test on your hard drive and that will tell if it your hard drive.

Check your PSU 12 and 5 volt during stress test. Run a S.M.A.R.T. test on your drive.
