Challenge : cmd uninstall of video drivers

[jsimon]

Hi,

I'm having a problem with a Toshiba laptop where apparently my video configuration consider the external output as primary video output, and not the actual laptop screen. I don't normally see anything on my screen, using the fn shortcut to change output doesnt work. I can't see anything from the bios either. I can open up window though so I would like to execute a script from a usb key that would uninstall my video drivers.

Anyone has an idea how I could do that?? Is there any dos batch command to uninstall something? The video card is a nvidia geforce 6600.

And of course if someone has an idea how I can fix the original problem, I'm up for that too but so far I havent found any option! Thanks

You have or have no tried SafeMode yet?

[jsimon]

The problem stay the same, if I get into safemode I still can't see anything. I've been hitting F8 to go to the safe mode menu, and then trying a few different options, trying randomly with the arrows the second, the third option, and so on but without luck.

I've been able to boot with the screen working again, but I have no idea what I did to fix it, and when I closed the computer, I lost the screen again...

So I'm down to trying dos commands to fix the problem...


And I forgot to say but OS is windows XP professional.

Can you even see the safemode boot screen?

If you cant see that or the BIOS, its not a driver issue, the card is either:
Dead, cable disconnected, not correctly seated.

No... I believe it still work, it is a software issue not an hardware one. If I plug in a computer screen I will get something, but the problem is I don't have one and I'm trying to fix the problem without it. That's why I called the thread challenge.

the built-in LCD is busted.

Well, sounds like that or the wires that connect the screen to the motherboard have come loose. If the screen were working properly, you should still see the BIOS screen when you turn the computer on.

If you feel confident enough doing so, you can open up the laptop casing and check the wires leading from the screen portion of the laptop into the base. (Doing so will void your warranty if one still exists.) If you're not comfortable doing this, take the laptop to a professional and let them check.

BC is probably right.  You may try this:  Get into Safe Mode/ Device Manager and delete your monitor driver / reboot.

He can't see anything from the moment the system is turned on, which is before Windows will even begin to load the video driver. Removing the driver will not solve the problem. If he's not seeing the BIOS, either the screen has died or disconnected.

"I can open up window though so I would like to execute a script from a usb key that would uninstall my video drivers".  So at one time you could see something, right?

"I've been able to boot with the screen working again, but I have no idea what I did to fix it, and when I closed the computer, I lost the screen again..."  At that time Safe Mode
did work, right?
