I'm having trouble with this Gigabyte Motherboard Z87X-UD3H as first time PC builder. When I try turning on the computer the motherboard goes on reboot-loop with this error PCH initialization error and I have no clue what the problem is or what it means.
I have tried updating Bios, but when updating bios it's recommended to load optimized settings, like that after rebooting it will auto detect the new bios, but that only gets it back into the reboot-loop.
I've sent the MOBO back to dealer and they agreed it was defected, but when new mobo arrived, I get the same problem, so far 3 same model of the MOBO and all with same error.
So I guess it cant be the motherboard.
I've removed graphic card, tried other sockets. Tested all possible way of mixing/removing Memory stick.
Sent CPU for testing, report says its fine.

If anyone got any idea I would gladly take advice and try it out.
Or if you need more info just ask, I'll try my best to provide.
