So I was playing BFBC2 last night when suddenly my computer just shut off by itself. I left it for a while and tried again and nothing. The power light on the case lights up for 1 second and then goes out. I have tried a different power lead, made sure the 24 pin and the 8 pin power connectors are sat right. I tried the jumper putting a paper clip in the green and black 24 pin, still nothing. The green light is on my motherboard. I'm not sure if this is a PSU or motherboard issue ? Any help would be greatly appreciated.
 
From past experiences I would have to say this is a PSU problem.

I woke up one morning and my computer would do the same thing (all the lights and power come on for about a second then turn off instantly). I changed the PSU and it never happened again!
