HELP!!! Loading Windows XP error!!!

[DNA of FLASH]

Well... I've been installing some new hardware (DVD-ROM) (after succesfully installing Win XP) and while it was detecting it it, the windows just stopped responding and then after a while I've restarted a computer (thinking it is just a little freeze )

the start up went just as usual but the windows XP start-up logo never showed up - instead just a blank black screen, and then it told me (really smart) that windows xp cannot start because the following file is corrupted or missing - hal.dll , please obtain the copy of it.

I've tryed enything I could, (safe mode, etc. nothing works)

anybody?
