Did you try pressing F12 as soon as you turn the computer on to get it to boot in safe mode? Keep pressing F12 until hopefully you get the start-up screen.
I just had to do a complete system restore on my laptop a couple weeks ago. Laptops now do not come with restore discs so I had to have dell send me them and they walked me thru restoring it. It was not easy and I had to download all the drivers off the Utilities disc.
I wish I could be more help.
