For some reason my computer becomes unresponsive after sitting going to standby, but only sometimes,
like two-three times a week. The screens go blank, so I try to remote desktop it and it says :
A Device Attached to the System is not Functioning.
Does anyone have idea what is this about. i have checked the Event viewer and can't find anything regarding
issue. also checked by update VGA driver. my OS is windows 7 Professional 64 bit.
