I built a new computer last weekend:
OS: Windows 7 64 bit (clean install from disc purchased when it was released in 2009)
MB: Asus P8Z77-V LX (Intel Z77 chipset)
CPU: Core i5 3570k (stock – no OC)
Memory: 16 gigs of Corsair XMS3 CMX8GX3M2A2000C9
SSD: Intel X25-M 80GB SSDSA2MH080G2K5
HDD: Western Digital Caviar 1TB WD10000LSRTL (aka WD1001FALS)
PSU: Antec Earthwatts EA-650
Video: Onboard CPU video for now, have not chosen a graphics card yet
The problem I am having is that this machine will neither sleep nor shut down properly. Telling it to do either results in the monitor and hard drive being powered down, but the fans keep running, and it will not wake up from this state. I have to hold the power button for ten seconds to force it to power off, and then when I turn it back on, it either boots normally if I was trying to shut it down, or it resumes from hibernation if I was trying to put it to sleep.
Turning off hibernation just causes an error message at startup saying the computer was not shut down properly. I tried powering it off in safe mode, and it just hung at the shutdown screen. I have also tried it without the HDD hooked up, so the only drive is the SSD. No difference.
When I first encountered this problem, I had several things missing drivers in device manager. Installing those drivers made no difference. I had already installed SP1, but in order to rule out some sort of problem with it, I first uninstalled it, and then completely reinstalled Windows. Neither made any difference. I have tried using the latest drivers found online for everything, and the ones on the included DVD. No difference.
I read about a problem which could cause something like this in the pre-sp1 version of Windows 7, and Microsoft had released a patch for it, so I tried that as well. No difference. I updated the bios to the latest version, but this as well changed nothing.
Following advice found online, I have played with the various settings in device manager and the power profiles page regarding which devices can wake the system from sleep, which devices are to have power cut during sleep, etc. Nothing makes any difference. Power to my USB devices is not cut during sleep, as the light on the mouse is still on when I try to put the machine to sleep, though it won’t respond to the mouse, keyboard or power button.
I used the POWERCFG tool to generate a report, and while it does give several errors about USB devices which won’t go into low power mode, I have eliminated this as an issue by unplugging all USB devices and disabling the USB hubs and controllers in device manager while attempting to put the machine to sleep. It still hangs and must be hard reset.
Aside from the USB issues (which obviously are not the root cause), the energy report also mentions this:
PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer.[FONT="][/FONT]
I do not know if that is the cause of the problem, but if it is, why has a brand new board been designed, released and sold with this sort of incompatibility? If this is the problem then presumably there is nothing I can do about it, and if so, this board is going back.
Is there anyone out there who has an answer for this problem, or failing that, who has the same board and does not have this problem?
If I have to replace it, can anyone recommend something comparable which will actually work right? Preferably something that Frys carries, as that is where I bought this one.
Thanks for any help anyone can provide.
