Well i got a old psu off a buddy on here to get me back up and going. I think it is dead. The motherboard's green light comes on but when i click the button all's i hear is tick tick tick tick and then it just stops. checked all the plugs etc etc.

I'm just guessing its dead it's pretty old i think maybe 4 to 5 years old or older.

Just wondering if there's anything else i might try before i buy a new psu.

You can try jumpstarting it but it sounds like its toast

Where is the ticking noise coming from?

Make sure you only have the PSU attached to the motherboard connectors and nothing else.

Yeah the ticking is coming from the psu.

None of the fans power up on the psu or anything the only thing that seems to get any sort of power is the mobo at least enough to get the green light on the board on.

A good chance there's bad caps.

Any bulging capacitors -> replace capacitors.

No bulging capacitors -> maybe replace capacitors anyway.

But first unsolder the big heatsink closest to all the wires that go to the computer, and take ohms/diode readings of each component soldered to it, as described here (http://www.repairfaq.org). Replace any shorted component with a similar one taken from a junked PSU (same general type, meets voltage, amps, watts, forward voltage, drain-source resistance ratings), even one with a far lower power rating (many old 200W ATX and even AT PSUs contain components rated for just as much voltage, amps, and power). Electrically insulate replacement component properly from the heatsink (depends on package -- some require nothing but silicone paste (no silver-bearing pastes!), others only the silicone rubber sheet, yet others also a nylon flanged washer -- not plain flat nylon washer -- for the screw). Test only after completely reinstalling the PSU case cover, including screws, in case something explodes.
