No display on wakeup

Not sure where to put this, if a moderator sees this feel free to move it.

I put my computer to sleep, and most of the time when I wake it up everything functions as normal except there is no signal sent to my display. I can open programs and such, I can hear the sound through my speakers. I've had this problem with 3 different Windows installs, 2 different HDDs, 2 motherboards (same make and model, blew a voltage regulator on the first), and 3 video cards. One video card was an ATI but I've always had Nvidia drivers installed along side it for dedicated physx. The constants are my PSU, CPU, RAM, and Monitor. I've tested my PSU with a voltmeter at 0% load and it is fine, I've changed my ram timings, voltages, frequency, I've changed almost every setting I can think of with my CPU, it even does it with everything at stock settings. It works fine if I make it hibernate instead of sleep. I've also tried disabling the hybrid sleep and that didn't help. I'm out of ideas.

I gave up on wake up issues years ago, disabled it and just turn of the computer if I don't need it.

It sucks because I don't want to lose all my work when I walk away from my computer for a while, but I don't want it to be on all the time sucking power and shortening the life of my components. I'll probably just leave it on hibernate, it does the same thing but it takes like another 15-20 sec to boot up. I just wondered if anybody knew an easy fix I may have overlooked. The one other thing I don't like about hibernate is you can't tell if the computer is hibernating or shut off because all of the lights go out. I'm just nitpicking though, it's not a big deal.

Of course I save my work before shutting of the computer. Leaving the computer on at idle for short periods at a time is not very wasteful and certainly will not kill of components in their useful lifespan.

No, but I have a 5 month old son and sometimes I have to leave my computer when I'm in the middle of something, then I might not get back on until the next day.
