"repair my windows xp"
Which XP version ? Home, Pro, Pro 64 bit, or XP MCE ?
Did you run a Repair installation of XP from the CD ?
If so, did you get all the way through Setup, and it was only after that your screen turned black ?
What problem were you trying to fix ?
Is this computer a laptop computer or a desktop computer ?
What make and model is the brand name computer, or if it's a generic desktop computer, what is the make and model of the mboard ?
WHEN does the screen go black ?
Is it black all the time including while booting, or is it black ONLY after the operating system is supposed to load ?
If the video is fine while booting, and it's black ONLY after the operating system is supposed to load....
- if you have a desktop computer, then that problem is usually easy to fix.
You probably need to load monitor drivers.
For 2000 or XP...
See response 9 here:
Boot into Enable VGA mode.
Note - that's missing this...
Remove any bootable CDs or DVDs you have in drives.
Press F8 repeatedly while booting, don't hold down the key, starting very early in the boot.
When the Windows boot choices menu appears, choose Enable VGA mode.
- if you have a laptop computer, you need to boot into Enable VGA mode the same way, un-install the video software in Add or Remove Programs, then install the video software again using the brand name's video software for your model, which probably have the proper monitor drivers for your built in display built into them.
If this is a laptop, if you get no video at all at ANY time while booting, your built in display has a hardware problem.
Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.
See response 1:
DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.
Some laptops will display on an external monitor without you having to do anything.
If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.
"I cannot go into "safe-mode". "
I tried to do a repair but when asked for my admin-password it says its not right . I tried hitting enter but don't know what to put after the C\: "
That must be in the Recovery Console - you pressed R to go there.
Usually there is no administrator password - you just press Enter.
CHKDSK /R C: (press Enter)
A space between CKDSK and /R, and between /R and C:
That takes a while to finish because it checks the whole partition Windows was installed on.
If it found any errors, they are mentioned in the summary displayed when it has finished.
type: exit (press Enter)
to close the Recovery Console and the computer will restart.
DO NOT press a key to boot from the CD.
See if the computer will boot normally into Windows.
If you get no video ONLY after Windows is supposed to load, see the info above.
