So hopefully this page should help you out.
Firstly its worth looking at some microsoft articles. Below are some links to microsoft articles on the issues relating to comptuer and hibernation issues. Some have hotfixes to be installed others potential work arounds. If any relate to your issue they are worth installing or following.

Various peices of software could be causing issues when resuming from sleep. Is worth doing the following:
- Make sure your Video Drivers are upto date. First install the latest from the computer manufactures website (such as dell, hp etc) if that does work try installing directly from the gaphics chip manufacter such as nvidia or ati.
- Update windows to the latest version. Make sure all Service Packs, updates and patches have been installed.
- Its possible there is a compatibility issue with the motherboard and computer memory causing this issue. Its worth updating the motherboads bios to the latest version.
- Check if "allow this device to wake the computer is checked" in Device Manager.
1. Click Start, type Device manager in the Start search box and hit Enter.
2. Select keyboard, it will display your keyboard, right click and select ‘Properties’.
3. Select the ‘Power management’ tab.
4. Check the “Allow this device to wake the computer” check box.
5. Repeat these steps for Mouse and Network adapters as well.
In making a computer "sleep" various hardware is used in the process. its worth going through the processes below to see if you can locate the problem.
- Reseat the graphics card and cables relating to the card and monitor.
- Check your memory outside of windows for errors. Help to do this here (if it fails the memory test then replace the memory with modules compatible with the motherboard)
- Check your memory while in windows for errors - Free program here - (if it fails the memory test then replace the memory with modules compatible with the motherboard)
- Check the video cards memory - Free program here - (if it fails the memory test then replace the graphics card)
- Click the windows button. Then type chkdsk /r /f in the search box and press enter to check for errors on the harddisk that may be restricting the computer coming out of hibernation.
- Check the hard disk for errors - Guide here - (It if fails the harddisk needs replacing)
You can make some changes to the power options as a work around to this issue:
Edit the power options : Windows Button > Control Panel > Power Options > Advanced Settings
Make sure you set the Turn Off Display to "Never", but leave "put Computer to Sleep set to say 30 min", your display should be turned Off or put to Sleep automatically by its hardware. Once the PC initiates the sleep mode it drops the video signal and the monitor will go into its own no signal sleep mode.
I hope this guide has helped you to solve your problem.
