[durrett syndrom]

ok i go to turn on my computer today running xp home edition. When i boot up, the 1st screen is the one you get when you hit f8 (boot in safe mode/safe mode with networking/Last know good configuration/etc). when i choose any of the options, the system goes to the next screen where is shows xp trying to load. it trys over and over then says "power saving mode" and shuts down. Please help.

PS: if i have to do a restore, is there any way i can put the computer on a network turned off and save the files before the restore? thanks a lot
