We've just bought several GA-X58A-UD7 motherboards, in order to change some old PCs. All seemed well... until a new system entered in standby and refused to wake up. Had to do a hard reset.
Config: GA-X58A-UD7. i920 processor, 6 GB DDR3 RAM (Kingston non-ECC ValuRam triple-channel kit, 1066 MHz, KVR1066D3E7K3/6G), WD2500AAKS HDD, ATi Radeon 2600 XT (256 MB RAM, DDR4, taken from an older Dell computer).
OS: Windows 7 Professional x64.
BIOS: F3G.
The weird part is that the system shouldn't enter in standby (Windows 7 power scheme used is "High Performance").
Any help would be appreciated.
