3. the answer to this question isn't so easy - just to update video drivers. there's another causes of this problem.
3.1 first of all we should check - is the screen perfectly blank, ot it's just backlit did not turned on. if there's no backlite and desktop appears on the screen and slightly visible - that may be BIOS problem. So you should try to update BIOS firmware, or if that doesnt work - try to rewrite it with older version of firmware.
3.2 if the screen perfectly blank - there may be problems with bios APM or ACPI settings ( S1/S2/S3 differs on providing with power internal hardware - read about it here http://msdn.microsoft.com/en-us/library/ms79827... ) if there any and also - with some additional h/w driver installed in OS. the solution is to change Power Managment settings in bios ( or just reset them to default ), check power managment settings in windows ( what mode has been used - hybernate or suspend?), check in device managment - does PC ACPI mode supported, and try to disable additional hardware drivers installed in system - i.e. bluetooth dongle, tvtuners etc...
to disable additional hardware use win+r->devmgmt.msc, right click on device, properties, disable
to disable additional software, drivers and services use win+r->msconfig (sorry, my interface isnt in english) in common menu choose "diagnostic startup" or something like this (2nd from the top)
3.3 concerning video driver problem - yep, may be it must be updated, but sometimes hardware better works with older version of drivers than with updated one. This can solve the problem too.
3.4 at last - it could be system fault - to solve - use win+r-> sfc.exe /scannow ( this tool will check windows system files, and if any of the are corrupted - will restore them form windows installation (or recovery) disk )
and afterall may be a good reason to check system event viewer, is there any errors or warnings.
