No monitor signal output until Windows login

Specs: Windows XP, Athlon XP 2200+ / 256MB PC2100 !!!
Howdy - first post which means I'm really stumped - I've looked on net for *hours* cannot find answer and I have always managed to sort problems out this way in the past.

So I told a friend I'd try to fix his "really slow" computer - I should have just walked away. So, old piece of stone age junk riddled with cat hair and viruses grinding away with 10+ minute startup - took out the HDD connected to my laptop and removed viruses - so far so good. Gave it the good old checkdisk and defrag.

Put it back in the presario and its much better but still a lame duck, even for the specs. Uninstalled all the crap that had been installed over the years but figured the XP home install was probably in need of a bullet in the head and a fresh install. It was then I hit the brick wall...

No monitor signal is output until the windows login screen. I cannot see anything AT ALL before this point and cannot see any POST, BIOS, XP Install setup - as a result I cannot force a cd boot and re-install windows.

Here's the details and what I've tried..

PC is using onboard graphics, no pci devices installed. Boots to windows fine, just no monitor output during startup. No system bleeps - but it definately can beep!

Pressed all the usual suspects at startup - F1, Del, tab etc during startup which halts the windows boot but still no monitor signal so I cant see what its doing.

Cleared CMOS
Removed CD Drive
Removed ALL IDE drives
Started in safe mode and tried every variant of msconfig startup
Re-installing XP Home fully automated from within windows
Wiggling the cable a bit and turning the monitor on and off.

Drinking even more wine - I wasn't really expecting this to do much to the pc

I finally went a bit mad and tried to re-install windows 'flying blind' but now the bloody thing wont even get to windows.

Any ideas? Thanks either way

Also, given the xp install was incomplete but now won't boot like before, is there a way to put the hdd back onto the laptop and delete or replace some files so it doesn't know it's in the middle of a failed re-insall?

Cheers guys

yep - my bad - its a presario s3060an

Here is the situation - the onboard graphics is partly broken and cannot output a signal until windows. The machine now tries to continue the xp install every reboot but i cannot see what is on screen to navigate out of this.

I'm thinking if i remove the drive and put it on my laptop I could remove the file/flag or whatever is telling it to try the reinstall and I could at least get it to boot to windows.

Any ideas?

why not replace the graphics card with a borrowed one till you get everything back together! That way the installation will work as it is the computer it was installed in....

Once replaced the screen will allow you to see what you are trying to do.

I can't see where entering the bios will do you any good till you get graphics repaired so you can see.

Trying to do wht you duggest might work but will probably not help much to get the graphics working!
