My dell inspiron is messed up

I have a dell inspiron 5160 and i had a problem with it and shipped it to dell to fix it cuz it had a power problem and they fixed that. So they just mailed my lap top back and so i turned it on and it was working fine and beginning to load up but then the screen turned blue and had an error and it said that system32/drivers/ntfs.sys was courrupted. So then i quickly shut off my computer and treid to restart it but ikept getting teh same error message. So i looked online on how to fix this and they said to put in the XP cd and click repair. So i put the cd in and it began to load and it said loading debugging something and it just stays on that screen. I left it to load for over 14 hours and nothing changed. Now when i start my laptop it just shows that dell screen and loads that white bar then the screen turns black. I can't go into safe mode or chose most current configuration. i can't do ANYTHING. Hooww the heck do i fix this??? PLEASE HELPP:

Send it back to Dell... It should be under warranty
