Blank screen UNTIL windows loads

January 10, 2010 at 23:10:36
Specs: Windows XP
When I power on my PC, I get a blank screen
UNTIL windows loads. I can't see the POST
process etc.

I do not hear any beeps from the computer - it sounds as if its starting like normal. After a few moments the windows xp login screen appears.

I've removed the battery from the computer in
an attempt to restart the bios - kept it out for
some time while the power was removed from
the PC but still the same problem.

I tried booting without the hard drive plugged in
- in this case it just stays at a blank screen.

I've also tried booting into bios - it seams as if
it goes to bios as windows does not load.
However, nothing shows on the screen.

Any idea what could be causing this issue?

In addition, I'm using an LCD monitor connected via VGA cable &
the video is integrated into the motherboard ie. no separate video

Did u change any settings in bios before? Give us a little background. Does the system respond like that since u built/purchase the system?

Is this a new occurrence or is this the way it has been since the beginning with this computer configuration?

The PC is a couple of years old and has been running perfect
up until now...

The other day it started to shut off by itself every little while -
the first thing I did was to check the outlet its plugged into
and everything was OK. I also plugged it into another outlet
and the problem persisted. Also, all other appliances plugged
into the same outlet are never disturbed.

I then felt that it could be either a hardware or software issue
on the PC (most likely hardware) but to be certain I wanted to
re-format the PC.

I went into the BIOS and made sure the temperature readings
where OK and steady - it seamed to be OK. I then in mistake
reset the settings on the same BIOS page to default setting
by pressing F8 (a shortcut on the BIOS screen to reset to
default) I assumed this wouldn't really cause any issues and
continued on...

I turned off the PC and popped open the hood - My windows
XP disc is on a DVD and not a CD and their are two CD drives
on the PC (one is a CD burner) so I unplugged both IDE & power
cables going to the CD drives and hooked one set up to a spare
DVD drive I had lying around so that I could proceed with the
Install of windows XP with a DVD.

I then booted up the computer to find a blank screen - again
everything sounds right and their are no beeps or squeals on
boot - only a blank screen. Eventually if I wait the windows
login screen appears out of nowhere and I can login again.

But if I login after a few minutes I'm back to the original
problem I was trying to trouble shoot which is that the PC
suddenly shuts of by itself (very strange)

So to trouble shoot the initial issue - I need to solve the "blank
screen on boot until windows login screen issue"

Any ideas guys??

I've also tried to plug back the 2 CD drives and still no luck. I've
even tried booting with the HD unplugged but still a blank screen.
I'm all out of ideas on this one...

Start it up and start tapping whatever key gets you into cmos/bios setup. Does the bios page open?

I tried getting into the cmos/bios page on boot but still a blank
screen. However, usually the windows login screen appears after
a while - this time it didn't. So it seams to enter the bios/cmos
page but I can't really do anything as the screen remains blank...

Do you have two outputs on the back of the motherboard for video? If so, try the other one, if you can.

"Do you have two outputs on the back of the motherboard for video? If so, try the other one, if you can."

If you have two video outputs, one is Primary, the other Secondary. Sometimes you won't get video until Windows starts to load if a single monitor is connected to the Secondary output.

Try the monitor on another computer and see if it does the same thing. I think the posting and bios screen are 640 x 480 and the XP splash screen is 800 x 600.

Perhaps the monitor just isn't responding to the lower resolution.

Hi guys thanks for the replies but no luck so far...

@ OtheHill, Tubesandwires

I only have a single video output on my PC, and its integrated
into the mobo.


The monitor works perfect on another PC and shows the
POST process etc. In fact, I tried another CRT monitor and
still a blank screen shows up at boot until the windows login
screen. I don't even see the windows logo flag at boot -
everything remains blank until the login screen appears.

I think we can rule out the monitor being the issue.

I even tried sticking in a ubuntu live CD to see if it would boot
from it but no luck...

Maybe I didn't go about reseting the bios correctly - this is
what I did:

1. Unplugged the power from back of PC that was feeding into
the power supply

2. Disconnected any power plugs connected to the mobo from
the power supply.

3. Removed the batter & kept it removed for approx. 10

4. After approx 10 minutes, I put back the battery and plugged
all power back into the mobo and back of the PC.

... and the problem persisted.

This ones really got me puzzled.

All graphics cards/chips have two modes they work in. The first mode is a VGA mode that is not dependent on any special installed drivers. This mode always works when the computer is first started. After the computer enters the operating system then the advanced features of the card/chip are activated by means of installed drivers.

I have never seen the condition you are now experiencing before but it appears the VGA mode is inoperative while the advanced driver modes still function.

You could test this theory by rolling back the display adapter settings in Windows but if I am right you then wouldn't have video in Windows either.

For the short term this is just an inconvenience but eventually you will need to see the POST screens and enter the BIOS screens.

The solution may be to install an add in graphics card.

@ OtheHill

Thanks for the helpful reply,

I'm going to try adding in a graphics card from my other PC and
see what happens...

I'll keep you all posted!
