Hey Guys,
My PC won't boot up at all. I don't use it often, and its about 7 months old. One day I turned it on and nothing would work. The lights are on but no ones home so to speak :P The power light is on but nohing comes up on screen, no beeping, no keyboard/mouse lights etc.
It also clicks when turned on about 2 clicks then 5 second silence and then repeats itself.
Anyone have any advice for me?
BTW: It maybe under a year old but no warranty anymore as I accidentally broke the warranty seal -_-#

Thanks :)

System:
Acer Aspire M5100
AMD Phenom Quad Core
2GB RAM
250GB HDD

(All parts are stock, came with the system, never replaced anything)

If you need anymore system info I can pop the hood and take a look :)

First thing to replace is the PSU, most common cause .

also u could check that the ram modules and cpu are securley in place

The clicking could be the hard drive trying to spin up. Best thing would be trying to figure out where ti comes from.
