Hey guys I've just built my first system and I'm having an issue with the PC turning on the fans and gpu fan for a second then system shuts down completely, I don't receive any info on the monitor or get any beeping, system specs are
Gigabyte 78lmt-s2p rev 5.0 mobo
And fx 6300 3.5 ghz CPU
Corsair 550w psu
G.skill sniper 1333 MHz 8gb ram
Hd7750 graphics card

I've added things 1 by one and tried to boot but I get the same result with each process, the CPU,mobo and ram are all brand new out of the. Box and have to been researched to suit each other, the psu has been tested and is in good working order, any ideas out there? I have it set up as bread boarding at the moment for ease of access. Thanks Darren
