Hi everybody,

I just put together a system with the following in it:

CPU: i7 3770k
Motherboard: Gigabyte z68xp-ud4
Power supply: Dynex 550w
Hard Drive: Seagate Barracuda 500 gb
GPU: Radeon HD6570
Memory: Corsair ddr3 1600 12gb

When I go to boot it for the first time, everything seems fine at first: fans spin, cpu lights come on and I even get the "everything is fine" single beep code. It stays on for about 25 seconds with no video output and then shuts off and automatically restarts. It does this over and over and never gets to the bios screen.

I've tried rebuilding it out of the case with minimal parts (cpu, ram, power supply) and it does the same thing. I've even swapped out the power supply but just gotten the same results. Does anyone have any idea about this? Any help would be much appreciated!

I'll admit that the power supply is probably the weak link in this setup, but I did swapping it out and got the same result so I don't think it's the problem. For troubleshooting I've tried including only essential parts (one ram stick, processor, motherboard, psu) and adding in pieces, also with the same result. Tried building it in and out of the case too. Is it possible to have a problem with the motherboard or cpu and still get that single short beep from the speaker at startup? Thanks for your help.
