Windows 7: Computer won't wake from standby/hibernate

Windows 7 Ultimate 64 bit
Computer won't wake from standby/hibernate

Hi, and thanks in advance for your help! I'm using Windows 7 64 bit.

My computer is several years old, and just a few weeks ago started having a problem waking from standby. Up until now, it had no issues going into and coming out of sleep.

Now, whenever it goes to sleep (whether due to inactivity or putting it to sleep manually), it won't wake up. The lights come on, the fans come on, but the monitor stays in standby. I've looked around online and found that many people get a black screen when booting up, i.e. the monitor comes alive and they may get a mouse cursor, but that's not what's happening to me. I don't get a black screen--my screen is never getting a signal from the computer. I have to do a hard reset, after which I get the 'Start Windows Normally' screen.

I've tried uninstalling and reinstalling the graphics drivers, changing hybrid sleep settings, using hibernate instead of standby, uninstalling random programs, etc, to no effect. I don't think I had any major windows or driver updates that caused it.

Any ideas??? It's driving me crazy. I'm getting to the point of trying a clean windows install... but what a pain that would be.

Thanks for any help you can offer!
