power supply makes grinding noise

[wannabe_hacker]

My power supply has been making some kind of grinding noise. I thought it might have been one of my HDDs, but that proved false. The noise comes about for no apparent reason. When it does happen though, I just hit the back of my comp and it goes away. Any info is appreciated.

eheh, that's not very smart, damaged PSUs have been know to literally explode,flames and all, if i were you, i would trash and spend $50 for a decent PSU off of www.newegg.com and hope it doesn't fry ur system before you do so
