hardware currently in
Intel Core i5 750 2.66Ghz (Lynnfield) (Socket LGA1156)
Sapphire ATI Radeon HD 4890 Vapor-X
Gigabyte GA-P55-US3L Intel P55 (Socket 1156) DDR3 Motherboard
OCZ ModXStream Pro 600w Silent SLI Ready Modular Power Supply
Samsung SpinPoint F3 1TB SATA-II 32MB Cache - OEM (HD103SJ)
G.Skill Ripjaw 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (F3-12800CL9D-4GBRL)

Connected 24pin and atx_12v, all of the connections are tight.
When i turn the power on all the fans spin up, so does the HDD.the motherboard logo comes up on screen like its about to post start. there is a beep then five seconds after it just shuts off and restarts 3-5seconds after it turned off it seems that it will do this all day long. ive tried starting with just the gfx, 1 memory stick and cpu but still the same happens.

cant realy take picture my phone is rubbish + loads of messy cables in the case.

Cheers

I've used that board for someone else are the ram slots correct (1 and 3) for that one I believe

Yeah thats correct mate, i've had no other option now but to take it into a computer shop to get some hardware tested (my other friends are console fanboys) ram is ok just waiting to see how it goes with the other stuff.

Cheers
