Windows 7 won't resume from sleep

[Durzel]

I've got a Shuttle SG33G5M that I recently installed Windows 7 32bit on, it was previously running Vista 32-bit. For a short time everything was running smoothly with no issues whatsoever, then in the last day completely inexplicably the computer has been unable to resume properly from sleep.

I press the power button on the remote, the power LED comes on the front of the unit, I hear the CPU fan start up, and the hard disk click into life, then... nothing. It just sits there with the CPU fan spinning away, no signal is sent to the TV it is connected to.

I can only get it to work at all by resetting it, at which point it boots like it would if it was cold-booted before telling me that Windows was unable to resume from the previous stored session (or something along those lines) and did I want to try and continue it or delete the session and start a new one.

What I have done so far to resolve it to no avail:

1) Installed the latest available Intel G33 Express chipset drivers
2) Ran Memtest (2 passes) on the 4GB of installed memory - no errors reported
3) Ran Scandisk on C:, no errors reported
4) Tried disabling hibernate and hybrid sleep, just having it sleep normally

No hardware changes have been made to the unit, and previous to this sleep problem it had been sleeping and resuming from sleep without issue.

I'm using the latest Nvidia display drivers for the card (8800 GT), they haven't been changed from the time it was working and now.

Can anyone think of anything short of a total reformat and reinstall that I could try?

What happens if you try to wake it using the power button on the Shuttle instead of the remote? Nothing different I take it.

My only other thought is that it could be an HDMI issue. Does it go straight into the TV or via an AV amp or something? You should try plugging it into another display with another cable, i.e. a monitor with a DVI cable. Also try another HDMI cable and / or another HDMI port.

The thing with computers is they don't stop doing something unless something is altered. I know it's an obvious thing to state but it's almost always a software issue in these worked yesterday/failed today cases.

From an elevated PowerShell prompt, enter the following commands...

Import-Module TroubleshootingPack
Get-TroubleshootingPack C:\Windows\Diagnostics\System\Power | Invoke-TroubleshootingPack

Windows will check your power settings and display options for fixing any issues it finds.

Hi,

Robbie G: Doesn't seem to make a difference if I press the power button on the front of the Shuttle or press power on the remote. Both wake the unit up, but 9 times out of 10 it will fail to properly resume. Black screen, "No Signal" on TV, WiFi LED on front of case not illuminated (this is usually a good sign of activity since it only comes on when Windows has finished loading/resuming).

Shuttle is plugged directly into the TV via HDMI (a DVI-to-HDMI converter). It has been this way since I installed it.

Arthur17: Will try that, thanks.

One peculiar thing I have noticed is that on a couple of occasions I have booted the Shuttle from cold and had no signal on the TV at all, but I hear the Windows startup sound. Another time when I tried to resume from sleep I got a BSOD (pretty sure it was nvlddmkm.sys) with the top line saying something along the lines of a device failing to respond correctly to a power event or something, I'm not 100% sure.

Part of me is wondering whether my 8800GT card has developed some kind of subtle failure, but in the meantime I'm going to reinstall Windows 7 from scratch.

Had an issue similar to this, so wait with eagerness to see if its solved mate, good luck!

Well Shuttle wouldn't show a signal at all today when booting from cold. The fan on the 8800GT would carry on spinning at 100% instead of settling down to normal speed after POSTing. Again the PC behaved as if there was a signal going to the TV because I could hear the Windows startup sound play, and could shut it down with the keyboard (Windows key, right, enter = shutdown)

This happened even after I disconnected the power from the Shuttle for an extended period of time, so definitely not a hibernation/sleep problem or a driver or "recently installed software" issue.

I reseated the card and the jumpers that determine whether it uses onboard HDMI or PCI-E slot for graphics, and it booted ok then (I'm typing this on it now). Not overly optimistic though that it will stay working though.

Regards that PowerShell thing, which I did yesterday before it started failing to boot at all, the only resolution that was shown was to disable the screensaver, which I did, so nothing obviously wrong there. The PSU in the Shuttle is only rated for 300W which is probably borderline for a 8800GT anyway, but it's been running fine for nearly 3 years.
