I am running win7rc 64 on a home build, asus m2a-vm mb, ati hd4670, 4 gig OCZ ram. All drivers are current win 7 or latest Vista64 drivers. Away device is disabled. Symptoms: when my computer is in use it performs as advertised, no problems with booting lockups or anything. after my machine sits idle for approx. 20 minutes the desktop stops responding to mouse and keyboard inputs, the monitor will turn back on. Sometimes the desktop will recover functionality in 3 to 5 minutes and sometimesit does not recover at all. The power options are set to turn off monitor at 20 mins, sleep: never, Hibernate: never. I have looked in all the usual places on the internet for suggestions and came up blank. P.S. I have checked and adjust the usb and lan settings for wake settings. I have turned off all the bios settings I can related to APM and AMD Live and Cool n Quiet and the C1E setting. I'm at a total wall Please help.
