|Oops - so this isn't a laptop.|
In that case, clearing the cmos by moving a jumper and moving it back, or removing the battery, will probably remove the password.
"It showed the set up screen before it hands it over to OS (the F12, and F2 for the settings ) I was able to see that its after that it went blank....when I hit those or left alone it went blank"
If you mean the display turned black once the operating system was loading....
I've had this happen several times.
Sometimes that happens when the specific drivers loaded for the video don't detect the monitor properly, and when they don't, sometimes nothing is displayed. Windows loads fine otherwise - you can see the hd activity led blinking as it normally does.
That can also happen if you have set your Display settings for one monitor, then changed which monitor you have plugged in. E.g. a CRT monitor is often capable of being set to settings most LCD monitors cannot display.
Also, that may happen the first time you boot after the computer has been shut down, if the monitor was not powered on for a least a few seconds before you booted the computer, but in that case you will have video in Windows the next time you boot.
(If you have no video in Windows, if your desktop screen loads without you needing to enter a Logon password, when there is no more hd activity, press Alt-Ctrl-Del, then Alt-U, then U to shut down Windows normally.)
Boot the computer into Enable VGA mode and load drivers for the monitor.
Remove any bootable CDs or DVDs you have in drives.
Press F8 repeatedly while booting, don't hold down the key, and when you see the boot choices menu, choose Enable VGA mode.
Enable VGA mode loads everything normal mode does except it forces Windows to use default VGA drivers that all monitors and video adapters support rather than the specific video drivers loaded in normal mode.
When the desktop has loaded, the display will likely have fewer colors, the resolution will be lower and the icons will be larger.
RIGHT click on a blank area of the desktop screen, choose Properties (goes to Display Propertities).
Choose Settings - the Advanced button - Monitor tab - Properties - Driver tab - Update driver
No, not at this time, Next
Install from a list..., Next
Don't Search....., Next
Choose Plug and Play Monitor
OR - if you have the drivers for the specific monitor, choose Have Disk, and browse to where the drivers are, and load them.
Save settings, reboot the computer normally, you should have video after Windows starts to load.
NOTE that XP's Plug and Play Monitor drivers have probably not changed at all since Windows XP was first released.
If you have specific drivers for your monitor, or if you can get them from the manufacturer's web site, you are much better off loading them instead of Plug and Play Monitor drivers, especially if you are using an LCD (or Plasma) monitor, because you can choose settings in Plug and Play Monitor mode that can DAMAGE an LCD (or Plasma) monitor.
El-cheapo LCD monitor makes/models (e.g. Acer) may not have any specific drivers available for them, but better models do (e.g. Samsung, LG, Viewsonic). If you have the CD that came with the monitor, there may be an installation prgram that installs the monitor drivers on it, or there may not be, and you have to use Have Disk at the above mentioned location to point to where the drivers are on the CD when you change monitor drivers - Windows requires you find the location of the *.inf file for the drivers - it may be in a folder or a subfolder on the CD, not in the root folder. Or you may be able to get a drivers download for your model from the manufacturer's web site, and use that.
If you can load specific monitor drivers, Windows by default only shows you the settings that both the monitor and the video drivers support - it is NOT recommended you disable that when you have an LCD (or Plasma) monitor, because it is possible you could choose a setting that will DAMAGE your monitor.
Why Enable VGA mode?
Safe Mode also loads default VGA drivers, but it also doesn't load a lot of other things that are loaded in normal mode.
You can't change Monitor drivers in the Display Properties in Safe Mode.
If Enable VGA mode works, normal mode doesn't, as far as this problem is concerned, no monitor drivers are being loaded in normal mode, or monitor drivers are being loaded but the monitor can't display because the settings are wrong for the monitor model, or if you have other video problems or problems after installing video related software your problem is probably caused by something to do with your specific video drivers.
If Enable VGA mode doesn't work, whatever your problem is, is probably not caused by something to do with your specific video drivers or monitor drivers or lack of monitor drivers - something else is wrong.
If Enable VGA mode doesn't work, normal mode doesn't work properly, but Safe mode does, whatever it is that was wrong is probably not caused by something to do with your specific video drivers or monitor drivers or lack of monitor drivers, and it's something Safe mode doesn't load that normal mode does.
If you need to un-install video drivers or other drivers or software because it/they are the wrong one(s) or for whatever reason normal mode won't work properly because of some software that was loaded , sometimes some things, e.g. video drivers, cannot be un-installed in Safe mode, but if the computer will boot into Enable VGA mode, you can un-install anything you can normally un-install in normal mode.
