I have a OCZ Powerstream 520w PSU- The other day I noticed a sound emanating from my computer which was turned off. so I popped the side panel off and located the sound which was deffinitly comming from the PSU. it sounds like a camera flash recharging over and over. Then I notice that the mobo power light was blinking along with the sound. so I conclude the PSU is not providing constant power. So I checked to see if there was any dust in the PSU while the power was on but computer off by spraying dust off (I know, not smart) there was no dust but the noise stopped and the light went constant as soon as I stopped spraying the problem returned. Any Ideas. What do you recommend Thanks Aaron
