PC not starting up.

So I've had this pc for around 2years now. Now it's not starting up. It dies after a second or two.

try and get a new psu, the one ur using looks pretty sketchy. Are you running any oc's because the stock cooler might not be enough

also, try clearing cmos

Nah processor's not oc'd, already tried clearing cmos, still nothing, guess it's just because it's a generic psu.

What steps have you taken to troubleshoot so far? It could be as simple as reseating all the power cables going into your mobo if you haven't already. 

If you already have done that, try following these steps to test if your PSU has gone bad:

1. Unplug your power cord and/or flip the switch on the back of the PSU in the position denoted with OFF or 0
2. Unplug every connector coming from your PSU (this is very important)
3. Using a bent paperclip, short out the green wire on the 24 pin header with any of the black wires, like so.
4. If you have a PSU that shuts down its fan under low load, or a PSU that is fanless, connect something small like a hard drive to it.
5. Plug in your power cord and/or flip the switch on the back of the PSU in the position denoted with ON or I

If the PSU does NOT power on (the fan/hard drive you connected should start spinning) after following these steps, your PSU is in all likelyhood defective. Request an RMA.

If the PSU DOES power on, then the problem is most likely your motherboard.
