Bootloop... Motherboard Issue? (Gigabyte Z68X-UDH3-B3)

[Nrubin999]

Hello. I am new to building computers, and built my first rig about a week ago. I installed windows today, and rebooted after installing updates. Upon restart, the computer turns on for 2-3 seconds, and shuts of for 5. This cycle repeats indefinitely. Here is my build -

Intel Core i5 2500k Processor
Gigabyte Z68X-UD3H-B3 Motherboard
Nvidia GeForce GTX 570 Graphics Card
OCZ ModXStream Pro 600W PSU
Corsair Vengeance 16gb (4x4) RAM
Western Digital Caviar Black 1tb Hard Drive

The computer was working 100% - everything fine. I've tried a lot already, taken out the CMOS battery, stripped the components to the bare. Nothing seems to work. Just want some help - wondering if it's a motherboard problem (the infamous Gigabyte Z68 "bootloop") or possible the PSU/Processor/RAM.

When I turn the machine on, the fans start, the lights on the motherboard turn on, the heat sink starts up, and almost immediately shuts down (2 seconds). I cannot access the BIOS, as when attached to a monitor - doesn't show anything. I really need some help with this, I have tried so much. Wondering if it's a motherboard issue, and I should just return it/buy a new one.

Good, we'll wait for the new mobo to come and lets hope it gets off fine.....

Try to boot with only 1 RAM stick.

I know this is an old thread, but mine appears to boot with only one RAM stick. What does that mean?

just to share... ive hade same issue on my board, tried everything and finally bought a Sabertooth with i7 ...

But i still have my old Ga-z68-ma motherboard.. and since i want to salvage it (with my i5 2500k) i noticed my heatsing over my BD82Z68 was really hot

Put the board on the freezer for an hour,.. and it booted into BIOS for about 20 second befor it hang and so the boot loop again...but i had a chance to load optimized Bios and reboot before...
So now im looking at a chipset overhat issue... will look for new paste and maybe a bigger heatsink on the chips.. more to come
