Hi there,. I recently brought my computer to my families to do some work over the holidays...Basically whats going wrong is when I plug in my computer ( a HP a500n ), the power supply on the back blinks rapidly and there is a clicking sound if I lean close and listen. This has happened once before after a power outage. I brought it into best buy who for 24 bucks shipped it out to one of there repair stations to be looked at. Two weeks later I got it back they told me all it needed was a reseat of ram and what not and a cleaning and it fired up. Interesting....ive had it back for about two weeks now and its happening again. Ive tried reseating the stuff myself but it didnt happen. Im suspicious they didnt do anything and the long duration of shipping reset it somehow? Any ideas or suggestions?
