Downgraded Version Motherboard replaced during warranty
So just now i checked the motherboard revision and the graphics chip on it . Dell has replaced my motherboard with a older refurbished version even though their own bios update caused the damage to my motherboard.
It has a ATI 1 GB 5470 HD instead of the one that i was having before the replacement (ATI 550v 1GB)
which is better than 5470HD
Does dell always cheat like this if people are ignorant ..wow!
