Monitor goes to sleep mode instantly

[AVA]

When I turn on my computer, I see the manufaturer logo,
the WindowsXP Home edition logo and then, WAM, the monitor
goes to sleep mode. I can enter to my account in the
blind (by the sound I know that) and turn off the computer.

If I start in safe mode I can go all the way and see
everything (I could clean and defrag). But after
restarting, the monitor goes to sleep again.

Sounds like it may be a video card driver problem, if it works OK in Safe
Mode. Boot to Safe Mode and go to Start/Run and type msconfig and select
OK. Click the BOOT.INI tab and place a check mark in the /BASEVIDEO option.
Press OK and reboot.

If this restores the display, you need to get updated video card drivers or,
if you have recently installed new video drivers, use the Roll Back option.

To use the Rollback feature:
Open Control Panel/System/Hardware tab and click on the Device Manager
button. Click the + sign next to the Display Adapter item. Right click the
entry for the video card and select Properties/Driver tab. Select the "Roll
back driver" button and follow the prompts. This will roll the driver back
to the previous version that was working.

Thanks Ronnie, I'll try it. I had just recently changed
my monitor because the original, just turned off and
started clicking.

I let Windows XP recognize the hardware. It worked well
for a couple of days though.

Yeah, this can happen if the resolution is not supported or the refresh
rate is not supported as well. You could also try this:

Boot up the computer, Press F8 until the menu for Safe Mode shows up.
Instead of selecting Safe Mode, select VGA Mode. Now it will load XP
normally, but with the lower video settings.

Like Nathan said, it could be set at a resolution that the monitor does not
support. If my instructions do get you back into XP, normal mode, try
setting the resolution to a lower value. Control Panel/Display/Settings.
Move the resoulution slider to a lower setting.

Just a little note as to how monitors work for your future reference
AVA. A monitor has information that it send to the computer called
EDID. In this is contained information such as the maximum resolution
and maximum refresh rate for each resolution (including all supported
refresh rates). If your previous monitor was able to do say 1600x1200,
but the new monitor can only do 1280x1024, then it is out of range and
will often cause the screen to go blank. Also, if the refresh rate is
set at say 80 Hz and the max supported for that same resolution is only
75 Hz, it will do the same thing.

Once you get back into Windows and open the Display Properties, it
should show the new information for the new monitor and allow you to set
it to anything the new monitor supports. This new information has not
yet taken over the old upon booting Windows and this is why you need to
use either VGA Mode or Safe Mode to return it to a lower setting so that
the new monitor can be configured.

Ronnie, Nathan, thanks a lot for ALL your help. I tried
all of your info. The problem was the monitor driver.
The resolution was too high for that monitor, but Windows
XP didn't have the right driver. After a sleepless night
I got the right driver from the manufacturer.

Nevertheless your help was unvaluable, because I could use
that computer at a lower resolution to see your messages
and search the drivers. Thanks a lot, AVA.
