I've noticed for the past 6 Gigabyte boards I've used in client builds there is a boot cycling problem one way or another. After shutdown and waiting for approx. 10 seconds booting up again results in boot cycling and results in the board reverting to using the backup BIOS which still boot cycles. Even after copying the new BIOS to the backup BIOS boot cycling still continues. I end up flipping the PSU switch and unplugging the power cable and waiting for a few seconds before the board would boot past POST screen.
Has anyone else encounter this with their new Gigabyte P67/Z68 boards?
I've had 3 builds with other makers, 2x MSI and 1x Asus and those board did not exhibit this problem, both boards are P67 boards.Facts about Boot Loop:1)
On a cold boot your motherboard will POST up to the "Memory Testing" (which is like the first 3 lines on your POST screen) line and then restarts on it's own. It will continue to do this for a infinite number of times, theoretically. If someone actually wants to sit in front of their computer and start a count on how many times it restarts, be my guest.2)
Restarting will not work, as it continues to boot loop. You'll have to hold down the power button for 5 secs (or whatever amount of time) until your PC manually shuts down. Turning it back on immediately after a shutdown continues the boot loop, you must wait at least 20-30 seconds.3)
In order to get the board to boot properly you'll first have to turn off your power supply (the switch on your PSU if you have one) and pull the power cord. Wait approx. 30 seconds, reinsert the power cord, flip the switch and press the power button. This should get your system to boot normally on 80% occasions according to my experience. Some members have stated that the CMOS must be reset, 24-pin mobo plug needs to be unplugged and CMOS battery has to be removed. You are free to try those methods if the pulling of the power cord method does not work.
There have also been reports of disabling certain options in your BIOS that will remedy the boot loop. First off, those people were not experiencing a boot loop, just a hiccup on a old chipset.
This boot loop problem unique to P67/Z68 chipset and so far most relevant on Gigabyte boards.
At the time of this writing all Gigabyte Z68XP
version motherboards only have 1 BIOS update to choose from, which isn't really a update at all.4)
No matter what you do, flashing the backup BIOS with the latest BIOS does not solve the issue. Sadly on some of the newer Z68 boards, THERE'S ONLY 1 BIOS!
