hav u used the restore cd ? it restorz the laptop to factory settings (like when you got it)
but remember, if u do so, u will lose all ur data
if u got sum really important stuf, u can use a boot disk 2 start ur pc in dos and use FLOPPY drives

to back it up
if theres too much data and its really very important and u can go any lengths to keep it, do this:
1.start it using a bootdisk in DOS
2.install sum old version of windows like 98 or ME
3.then using a network or cd writer, backup your data
4.use the RESTORE cd
