NO OS stated, XP"? never post without OS stated, or answer get 10x more harder, See? make it easy for the helper and get more help.....
no Monitor stated. (maker, CRT, LCD what?)
The monitor is not fibbing to you BTW, the PC did go dead or to sleep. seems its monitor monitor of some kind with DVI.

if the monitor works on other PCs then the monitor is not bad.
i Bet it works (old ones 2002, have a hidden deep internal sleep mode. and is not yours IM sure now) DVI IS THE ONLY CLUE THERE.
So PC is dead. this PC came with only VISTA new,

Hello

You can prevent the computer from going into sleep or hibernation mode by going to the CONTROL PANEL - POWER SETTINGS.

Once here, change the settings to High Performance.

You can also go into advanced properties and manually change all of the settings - including when the hard drives go to sleep (I set this to NEVER), when the monitor will go to sleep (again, I set to never).

Go to control panel, select Power Options and turn Sleep Mode off or set it how you like it.
Hope that helps.

Hi friend,

You need to start your pc then press "F8" button then select the safe mode option ....window will start in safe mofe....then you need to restart your pc again ...then it will work...

Go to Advance Power Settings.
Set hard drive to turn off a minute or 2 before sleep.
Set Hybrid and Hibernate modes to "Off"
Under USB settings select "Disable"
Under Multimedia select "Allow ....." also setup your screen to turn off ( pick how long monitor will stay on. you can also try going into the bios and setting it to default. save and reboot. let me know if this helps.

It could be a problem with the update. You could have used system restore to go back to before you installed the update. Re-imaging probably cancelled that. I would check for virus' before going any further. Download a program called malwarebytes (free version), install-update and scan. If nothing comes up try the system restore or uninstall the service pack. You can always reinstall it again later.

go to control panel power ption thern clik on hibernate
and enabvle check box of hibernation so it start from where u end

Where is the boot failing? Do you have anything on your screen?
