Strange one!

Ok so I built my new PC in work on night shift and it started first time and worked a charm. When I took it home at 6am the next morning and tried to turn it on the fans spun for like 1/2 a second and then nothing happened. I plugged it directly into the wall and it worked flawlessly since then so I just presumed it wasn't getting enough juice through the adapter for some weird reason.

But yesterday I was playing Dues Ex and talking to a friend on vent when my PC just turned its self off (I don't mean shut down, I just mean suddenly no power) and wouldn't come back on. I unplugged everything and put it all back together and it still didn't work but after lots of swearing and small cuts on my hands provided free of charge from the PC it eventually turned on when I pressed the power button for the 6546216549591st time and stayed on until I turned off at night.

This morning I go to turn it on again and the same problem comes back with the fans, maybe 1/2 a second of power then nothing. So after taking everything apart and putting it back together again still nothing happened so I took the PSU from my last build Corsair 650w modular? and now it works again. I have got an RMA for the PSU and will send it away tomorrow but I just want to know if anyone else has had this problem and if it is defo the PSU? I mean today I was 100% that it was the PSU but I always have that little doubt in my mind lol

This might sound silly, but have you double checked that the motherboard isn't shorting out on the tray? I've had that before on my Lian Li case where I didn't use the risers correctly. Also, that a small screw isn't trapped there.

If you've changed the PSU and it's now working though, probably is.

Yeah I used the risers that came with it so I doubt it is that as it just refused to come on until I used the old PSU this morning. I suppose when I get home tomorrow morning I could put the "faulty" PSU in my old build and see what happens.

I just thought it was strange it was fine when I built it in work and then stopped working at home . . . until I plugged it straight into the wall.

I should add that I let memtest run for about 5/6 hours once I got it working yesterday and I had previously let prime95 run for a good 8 or so hours without a problem.
