PSU failure?

[jaws104]

Hi,

Just put in second drive (SSD) and now PC won't switch on, light on motherboard is lit though.

All the connections seem secure, reckon psu failed? I actually forgot to plug in power supply to ssd when I first switched back on, was just the sata cable in,

I could get a multimeter on it tomorrow but wondering if anything else I could check in the interim, at a bit of a loose end now!

I have everything, pc was running fine before I put ssd in.

I removed ssd and ram just now and tried but still nothing. No beeps, no fans spinning, nothing. But that light on mb is lit.

**EDIT** -- the little two pin 5v connector from power button to motherboard had got disconnected, sorted now
