Greetings,
Within the last week I purchased and installed a GA-Z87X-UD4H motherboard and i7 4770k CPU on Windows 7 64bit to replace my old EVGA 790i Ultra SLI Deluxe + Intel Q9550 CPU on Windows Vista 64bit. Performance is excellent, except that I have been experiencing a problem with my USB devices being recognized when I wake the computer from sleep mode.
When the computer goes into sleep mode, I am unable to wake it back up from sleep mode, as the computer does not respond to input from either my mouse or keyboard. It will not wake up if I normally press the power button, either . My only option is the reset button or holding down the power button. Upon the next start windows asks me if I want to start normally, but I can't select any options because the keyboard and mouse continue to be unresponsive. Only after the timer has counted down and windows fully boots normally will my keyboard and mouse begin working again. Today, I also had the keyboard and mouse being unresponsive when I turned on my computer from a complete power off. I never had this issue with my old MOBO and CPU, and the GPU has stayed the same between upgrades. I have the keyboard and mouse plugged into the USB 3.0 slots on the rear IO panel, if that helps.
Could this be at all related to the Haswell USB 3.0 problems I've read about? Supposedly those were fixed with a C2 something or other.
My current BIOS version is F5, can this be fixed with a BIOS update to F7? Also, how do I go about Flashing my BIOS? I know that this motherboard has a Dual BIOS and I'm not sure how that works. Can I flash one BIOS and keep the other, or do I have to flash both? I want to avoid bricking my motherboard, so should I use the Windows @BIOS software to flash my BIOS or do it with a USB, and how do I go about this?
On another note, I have a second Gen Corsair H60 watercooler. It has separate power connectors (both three pin) for the fan and water pump. Corsair says the pump needs a full 12 volts all the time. At the moment I have the fan power connector plugged into CPU_FAN, and the radiator fan power connector plugged into "CPU_OPT". In the BIOS I have the CPU/OPT Fan Speed Control set to "Disable" so both run at maximum speed. How should I configure my setup so that the pump receives a full 12 volts (runs at max speed) while the radiator fan is variable based on reported CPU temperature?
I apologize for the lengthy post, but I wanted to include enough information up front so that I might not waste other people's time later.
Thanks,
Alex
