Windows 7 blank screen after sleep

[MJoshi]

I used to be able to put Windows into Sleep mode but now after waking the computer, I just get a blank screen?

I have to press and hold the power button to force the computer to shut down and wait a few seconds before starting it up again.

Sounds like the video card driver is not resuming from sleep. I had this problem too. Updating the driver (or removing/reinstalling the current one) may help. Good luck.

are you overclocked any? I used to have the same problem when i specified motherboard voltages, then i set everything to auto and the problem went away.

^^I like his answer too. It reminded me about an Abit board I had. After years of overclocking it started to die. Even with everything STOCK, the CPU clock would vary +/-5-6MHz or so. I.E. sometimes I'd have a 2.2GHz CPU, sometimes a 2.292GHz CPU a 2.185GHz CPU, etc.

I had the same problem w/the monitor not waking up when resuming from sleep. Just wanted to share that.

What motherboard? If its an Asus P67 or Z68, turn off PLL overvoltage in the bios.

I had this SAME thing happen after I did a reinstall of Windows 7...

I spent hours F'ing around with settings...etc...

You know what finally somehow fixed it for me?

unhooking everything from my computer (during a cleaning session) and plugging it back in...

I don't know if it was the order or if Windows re-recognized something but it worked for me.

This is indicative of high resistance in a connector someplace. Probably a SATA connector.

Wish I could get my P67 to sleep. Half the time it won't resume but I gave up on trying to fix it. My wife has the exact same PC and it sleeps fine... so aggravating.

Thanks for all the replies so far.

The motherboard is an Asus X58 series.

I am not overclocking at all and I have the most current graphics card driver.

I tried turning off the PLL Overvoltage in the BIOS. The screen did come on after waking the computer however, I could not log into Windows. It came up with a software error each time I tried to click the login icon.

I have noticed that when I press and hold the power button to force the computer to shut down after it has been woken up, I have to power it down again and on otherwise the computer does not boot properly?

I'm using the same series board and had a similar issue. Are you running a single disk, or are you running a RAID setup on the ICH10R chip by chance?

This will sound weird, and may not be anything for you- especially if you're running in single disk mode, I was running 4 disk RAID 10. I made a small portion of the 4 disks into a RAID 0 array, and used the rest of the space in RAID 10. I was trying to resolve a different issue at the time, and not the sleeping troubles, but this change did fix it.
