DELL CHEATED ME YOU PEOPLE CHANGED MY MOTHER BOARD MANY TIMES AND NOW JUST AFTER MY WARRANTY COMPLETED I PROCESSOR RAM AND HARD DRIVE  STOP FUNCTIONING. I TRIED TO CALL DELL BUT THE RESPONSE IS THAT THEY SAY NO AVAILABLE. I HATE TO CHOOSE DELL. WHEN I COMPLAINED EARLIER THEY SAID UPGRADE BIOS. YOU ALL ARE CHEATING ME SO THAT ANY HOW MY WARRANTY GET EXPIRED.
