Re: Safe Mode with Blank Screen - No 1024 x 768 resolution

if you have a nvidia
graphics card installed,

and the driver is nvidia's

and you have the crt plugged
into that nvidia adaptor/port

and you are still getting a
default resolution,

then maybe the crt state is
set for a default resolution.

check around the crt for
buttons to press to initiate
the crt's setup, if it has any.

maybe it has the options
to modify the crt's state or
provides a "auto configuration"
mode.

another option is to open
the nvidia control panel and
also check if you can modify
the resolution for that monitor.

another option is to double
check your bios and see if
there are settings for graphic
or video shadowing.

other than the above, I have
no other suggestions other
than to consider transitioning
over to a flat panel monitor.

they are reasonable now and
their output are much better
than the crt's.

In normal mode, I checked Device Manager and the driver for the video adapter
was nVidia's.

I went thorough the registry and found one suspicious part and changed two
values (changes noted):
Windows Registry Editor Version 5.00

[HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO]

Well, now I can boot in Safe Mode with the resolution of 800 x 600. Device
Manager still indicates the driver is nVidia's. I have absolutely no idea
what's going on, but at least I got it working.

I have questions:

1. Is the above (dirty fix?) safe? Should I change more entries elsewhere?
Are there better ways to change them through Control Panel and such without
having to change them directly with the use of regedit?

2. I have only one monitor connected; I have never connected or tried to
connect more than one monitor at a time. (Originally, the computer came with
a Sony's monitor, but since I didn't like the quality of the display, I
switched to my old Viewsonic monitor. [Both CRT]). Why do I have two monitors
registered? (The Device Manager shows only one "default" monitor.)

3. I did a file search, and my system doesn't seem to have vgasave.sys. Is
it indeed a file? Is it critical to have it in order to boot in Safe Mode?

yes, vga.sys is the
basic resolution.

and may still be active
in normal mode if your
graphics display
driver crashed.

you can go to device
manager and check out
your display adaptor
drivers.

there might be a question
mark next to that reference
and the properties will likely
have the default vga.sys
driver enabled.

I would suggest you search
and update that driver with
one that is for your system.

but perhaps, you might try
to go to the home site for
that computer and check
out the downloads and
updates for the model and
download the most current
display driver instead.

incidentally, you may want
to download a freeware called
"siw" and it will scan your
registry for all the product keys
installed.

you will also get the data for
your windows.

it is possible that either the
home site will have the option
to provide you with restore
disks "or"

they will have the instructions
on initiating a factory restore
if your hard disk has a special
hidden partition with the restoration
files.
