Black screen ( WinXP doesnt load!)

[TheRealPimp]

Well i had this desktop
P4 3.06Ghz
128MB grafik card (Shared)
512MB RAM
160 HARD DRIVE
eMachineS T5048
----------
Well i tried to turn it on and the BIOS loads and after that, its all a dark screen. I cant even see the WinXp Boot screen.
i tried to reformat the computer the CD boots "PRESS ANY KEY TO BOOT FROM CD_" and the its says " CHEKCING YOUR HARDWARE CONFIGURATION or w/e.
you cna hear the CD running in the drive but the screen is just all black till i turn it off. I cant access the Safe Mode.
What cna be the problem and how to fix it PLZ!

sounds like either you got corrupted system32 files, corrupted video drivers or your on-board gfx is shot.

1) if you can try repairing first instead of formatting since that will most likely fix any system32 file errors.

2) if its corrupted video drivers you should be able to load into safe mode. spam f6 or f8(which ever it might be for your system) even if you can not see anything and see if it loads up at all.

3) if its a dead gfx card.... you are hosed and are gonna have to buy a new motherboard but in your case might be cheaper to go with a new computer. this is the most probable cause though as I had something similar happen this past fall and once I replaced one of my bad cards the problem was solved.
