Desperately Seeking Solution- Black Screen after Reboot

[Guest]

I lied a little, it's not totally black; since my pc is a notebook, if I tilt
the screen differently I am able to see more/ less- but never more than the
sharpest contrasts- I can only make out black letters on white background if
I tip it almost all the way back and hold my head on the side! DESPERATELY
BAD!
SCENARIO:
I'm downloading something from the internet, I get a warning from avast that
a trojan horse has been detected. It asks if I would like to schedule a virus
removal for the next reboot and reboot. I say yes. My computer reboots, but
once it gets past the Windows loading screen, it goes desperately black. I
force it to turn off, start up in safe mode- THE SCREEN DISPLAYS PERFECTLY-
RUN AVAST AND ADAWARE, they find nothing. Reboot. Same problem as before, but
I discover the system is still running fine, I just can't see the bloody
thing! I log in, run system restore- reboots, same problem; log in, run
avast- nothing.
I have turned the bloody thing off, WHAT oh WHAT WIZARDS OF THE BRAINIAC
WORLD can I do?
Disturbed slumber at best,

It sounds like your screen may have a hardware problem. When you first turn
on the computer is the screen dark or does it only go dark after Windows is
loaded? Most computers have a screen that displays the computer logo or the
BIOS POST. Do you see this screen before it goes dark?

"but once it gets past the Windows loading screen"
I see the screen saying Compaq perfectly, then also the one that says
Windows and shows it loading.
It is after that that I am blind- but only when I come up in normal mode.
Safe Mode performs fine.
Thanks.

I'm pretty sure there is a way to undo what avast has done within the
program. I can't remember the steps involved and I don't have avst running
on any computers here. I will be at a site that uses avast later today so I
will check it out. This will cause the trojan to get back on your computer.
You will have to use a different method to remove it. You could try posting
your problem in avast's support forum.

Another possibilty is that somehow you inadvertantly set the display to an
external monitor instead of the built in display. Usually there is a
combination of keys that will switch the display mode.

If everything works OK in Safe Mode you probably have a corrupt or
missing video driver. Safe Mode uses a vanilla standard video driver
that works with any video hardware. You will probably have to reload
the correct driver from a CD or from a download.

Good luck, jimbo

Go into safe mode, go to control panel, choose system. In system go to
hardware. Click on the device manager and find the video driver and
monitor driver. Delete them both and reboot the computer. It will
reload the drivers and should work.
