Computer/Monitor problem

October 3, 2009 at 16:45:13
Specs: Windows 7
After my computer sleeps my monitor won't "wake" up. My case fans are running, keyboard light is off, but nothing happens(sometimes everything turns off, and when I wake it up its fine). No DVI signal popups. After shutting off, messing with the cords for the monitor, turn on, it will POST, then windows logging in and it goes black, I reset computer and everythings fine, although sometimes I have to do this more than once.

On my mobo DRAW led will be red, then go away, then CPU led, then they both just go away during boot. Sometimes boot seq will also be red when starting to booting up. Also when I had it on hibernate it kept on coming back on every 5 minutes.

# Motherboard P7P55D ASUS
# CPU i7 750 stock
# Video card XFX Radeon 4890
# RAM : 2x 2gb OCZ gold 12800
# Power supply: OCZ Stealth X stream 700w
# Monitor ASUS 24" VH22
# Windows 7 Ultimate

I can obviously turn off sleep/hibernate, but I wanna get this fixed. In my bios there is the APM Configuration, I made sure wakeup by mouse/spacebar was enabled.

Something I seem to notice is that it works fine until it tries sleeping the 2/3rd time that day.

Disable sleep/hibernate.

Those features are designed specifically as battery-saving modes for laptops and are not reliable or desirable in a desktop system.

Every other computer I've had all work fine with sleep. It works fine with desktops.

I agree-I always use sleep/hibernate in any desktop I use. That being said, there are times when it doesn't work properly-perhaps it's an issue with Windows 7. I wonder what would happen if you disable wakeup by mouse/spacebar. You could also try updating the video drivers.
