Hey guys,
So a few weeks back i brought a new PSU, cause i brought a second gfx card so i could SLI however after i installed everything my computer would'nt boot. I thought maybe it was a PSU so i sent it back to scan they tested that and my motherboardand sent them back saying both were fine.

However after recieved the parts back and reinstalling them my computer wont boot unless i unplug the power cable from my harddrive(s) when it is unplugged i can reach the bios. But when its plugged in the cpu fan spins for a second or two then the machine powers back down.

Thanks for your help.

Sorry, I forgot to add that, I did switch out the power cable i'm currently on a nightshift at the moment but when i get home i'll try the sata cable in a diffrent port and a diffrent sata cable, And if it comes to it will stick it in a old system i have down stairs.

Do you think the motherboard is fine? cause i have 2 ssd's so would much rather it just be the ssd than have to fork out on a new mobo.
