Specs: Athlon 5200+ Asus M2N-SLI delux (nForce 570 AMD SLI board) nVidia GeForce 275 Windows 7 RTM (7600) I've tried everything i can think of. Just installed Win7 fresh onto my main machine, but when i send it into sleep mode the entire computer shuts off (is that part of sleep mode?) and no keyboard or mouse activity will wake it up. I have to hit the power button to turn it back on, at which time it fails to start until i hit the restart button. Then it comes on like normal and "resumes" windows back to the state i was at when i went into "sleep" mode. First off, is the computer suposed to shut down completely and all the fans stop? Secondly, i've tried playing with all the power settings i could find. I turned on/off hybrid sleep, i tried hibernating instead of sleeping and i even went into the bios and change from S1&S3 to just S1 and just S3 in the power mode (i don't even know what those are) and nothing has worked so far. I've installed the latest motherboard, graphics, and sound drivers that i could find. Any ideas? Anybody else in my boat?
