What version of windows are you running?

Have you tried to start the machine in safe mode?

JOLLYCORNER · « **Reply #2 on:** July 23, 2008, 10:41:07 AM »

I AM RUNNING WINDOWS XP HOME EDITION PACK 2
I HAVE TRIED SAFE MODE BUT IT FREEZES AFTER IT DISPLAYS A SCREEN FULL OF INFO

How long are you waiting after it "freezes"? safe mode can take some minutes to boot.

Also, please read this

No caps please.

JOLLYCORNER · « **Reply #5 on:** July 23, 2008, 03:21:32 PM »

I have tried starting in safe mode many times now and it always freezes after 1st screen full of commands. I realise it can take a while to load so i left it overnight but it was still in the same screen this morning

Carbon Dudeoxide · « **Reply #6 on:** July 23, 2008, 03:35:36 PM »

Is this a laptop or desktop?

I have looked briefly on the web: Good News = you are not the first to do this!

Bad News = looks like a Windows re-install is necessary to fix it if you have a laptop.

If desktop, looks like you can install another video card (system now has two cards), make sure that the bootup video is properly selected in the BIOS, then re-enable the disabled card. Match the new card, of course, to an available motherboard slot.

Best of luck!

Bummer... You're too fast for me... The Hare and the Tortoise - so few of us remember who won the race!

----------
From the Tortoise:

Try Last Known Good Configuration. I'm hoping the monitor device was enabled at your last successful normal boot and login.

Tap the F8 function key once per second or faster as you power up the system (or possibly restart it). The Windows Advanced Options Menu should appear. Use the up/down arrow keys of the keyboard to select the "Last Known Good Configuration" item and hit the Enter key.

This should boot your operating system normally using the previous registry settings for the last successful login (to normal mode - safe mode logins do not overwrite the registry settings for the last normal login). With monitor device disabled in the current registry and your inability to login; the previous registry settings should still have monitor enabled.

May be best to take it to a repair shop. They'll have an extra video card lying around.

Best of luck!

If it freezes in Safe Mode, I suspect, on-board video is shot.
I believe, in Safe Mode, Windows should load all default devices, and drivers, so even if monitor was disabled in Normal Mode, it should work in Safe Mode.
Borrow video card from a friend.

Something strange about this, have you been playing around with your bios settings?

Borrow video card from a friend.

He disabled his 'video device' - therefore, it won't fire up, even in Safe Mode.

This appears to be consistent with the experience of others with the same problem.

Another card in the same slot will also not power on - he needs to add a second card. Then, when he can 'see,' correct his error.

You could boot to Recovery Console and either try to enable display device or jump through a lot of hoops trying to restore registry to a point before you disabled the display. While I haven't personally used either of those methods, they look promising.

It worked for Ryan Lowe per Adventures in Disabling VgaSave. From within Recovery Console enter the following command, then exit and reboot (normal, safe mode, whatever works):
enable vgasave SERVICE_SYSTEM_START

or possibly:
enable VgaSave SERVICE_BOOT_START

The Recovery Console does not provide direct access to System Restore Points. If you're interested, someone would have to provide instructions off the internet.
Running System Restore from the Recovery Console (well, sort of)

Recovery Console is usually accessed from either the Windows XP Installation CD or a set of six floppy disks that may be downloaded from Microsoft. The Recovery Console media you use should match the current system on your computer; i.e. Home Edition or Professional, Original, SP1, SP2, SP3. In your case, I guess it's Windows XP Home Edition SP2.

Yes assuming like someone else said the video isn't shot, but that probably is not the case. Reloading Windows would cause the changes you made to revert back, but then you would lose everything.

Boot to Windows XP Recovery Console and enable the basic display driver. When you exit from Recovery Console, the computer should reboot. Hopefully, you would then be able to boot into Windows (either normal or Safe Mode) with a usable display. Then someone will guide you through updating the display driver and setting the display properties to what you want.

Did Ryan Lowe's Adventures in Disabling VgaSave not capture your imagination? Where's your sense of adventure? Spread your wings... Take a chance... This could work... It worked for Ryan.

The Recovery Console media you use needs to match your current operating system and service pack level (which you've reported as Windows XP Home Edition Service Pack 2). You may use either a Windows XP Home Edition SP2 installation CD or the appropriate six volume floppy set downloaded from Microsoft. See the links in my previous post. An Original Equipment Manufacturer (OEM) Recovery/Restore CD will not cut it.

thank you for all that advise I have tried recovery and the commands offered but no joy.

I can format and reinstall if it will fix, I have all my data backed up on exteranl HD
