My problem started with my system (TOSHIBA TECRA M2 laptop) not allowing me to update the screen resolution beyond 600x800 and 4 colors I believe.

I tried uninstalling and reinstalling the drivers for my NVIDIA geForce 5200, but it still did not work. I then disabled the primary video adapter which was listed as VGASafe. Now my screen is completely blank. I can hear the system working, as things load but can not see anything.

I then tried to boot into SafeMode in an attempt to use system restore, but whenever I select SafeMode hundreds of lines of text are displayed on the screen, but it never boots up.

Is there any way to enable this adapter without using windows?

The enable VGA mode was available, even though the text describing it would flicker between the real and garbled text. I clicked on the line containg enable VGA mode, and then was prompted for which operating system to use, again text was flickering between real and garbled. Windows XP Professional was the only option available, it is also the only operating system installed on this laptop. After clicking enter on the OS, the boot continued as normal, but still there is no display.

can you boot to safe mode with command prompt?
if so
Start the System Restore tool at a command prompt

1. Restart your computer, and keep tapping F8 during the initial start-up until you get options, select Safe Mode with a command prompt then press enter.

2. Log on to your computer with an administrator account or with an account that has administrator credentials.

3. Type the following command at a command prompt, and then press ENTER:


%systemroot%\system32\restore\rstrui.exe

4. Follow the instructions that appear on the screen to restore your computer to an earlier state.

Look for the most recent system checkpoint created before the errors to restore from

I was able to select safemode with Command prompt, but all it does is list a bunch of lines and then freezes.

(They appear to be the drivers that are being loaded, I am guessing here, because again the text flickers between real and garbled.)

The command prompt or windows is never displayed.

That appears to be the second to last. The last looks like agpt4p.sys
