Hoping for some tips on this one experts: ..Windows7 64 bit installed on ASUS M4A785-M motherboard with AMD Athlon II X2 Regor CPU. The MB Bios is updated to the latest as of 8-15-2010. There doesn't appear to be a firmware update available for the Corsair Force CSSD-F60 SATA II MLC Internal Solid State Drive (SSD).
Problem: After some seemingly random time of idle activity - never when I'm using it - the system goes offline with a MISSING BOOTMGR message. CTR-ALT-DEL to boot to BIOS screen shows the SSD drive is completeley missing. If I then turn off the power supply then turn it on again the SSD drive is now visible in the BIOS and system functions normally except of course for the 'windows was not shut down properly' message.
I've turned off every screen saver, power management, and otherwise hunted for anything that might be trying to put the SSD to sleep but of course I may have missed something so all suggestions are welcome.
I've also tried leaving active windows open like windows media player looping music or a continuous feed from a webcam. That didn't work either. It seems only an active session of some kind will prevent the problem.
