I bought the computer in my sig about a year ago. I've had rebooting issues for as long as I can remember. Overall i've been happy with this board, except one major issue. When I reboot my system will sometimes hang, shut itself off, restart and than get stuck at the post screen with the Gigabyte logo. The only way to remedy this, has been to shut down the Power Supply for a few seconds and than turn it back on. If i try to just do a reset, or even use the power button on the case... it will continue to hang at the Gigabyte screen. i haven't tested this extensively, but i believe it started happening when i went from 2GB to 4GB of ram... 4 is this boards max supported amount. I've tried all different combinations of ram, and don't believe it's faulty ram.

a couple of key points:
1. my power supply is a seasonic and worked fine in my older system.
2. gigabyte's website has a warning
"Because of chipset limitations, when using FSB 1333 MHz CPU with populating all DIMM sockets, memory frequency will be reduced from the original, and system instability or incorrect detection of memory module may be occur."
but i'm running 1066mhz so i know that's not it.

i'm also unable to overclock my CPU at all... even a value change of 1 to the multiplier causes it to do the shut off / restart / hang thing, except it doesn't display any image instead of at least showing the Gigabyte screen.

i know this is a pretty involved question, but i'm looking for any help because this has been driving me nuts for over a year. i stopped using ASUS to try Abit based on great reviews, had a HORRIBLE experience with Abit and decided to try Gigabyte. if i can't get this fixed, i'd rather just go back to ASUS since they're the only company of the 3 that has never given me problems.
