Once upon a time i got this laptop with nvidia 8400m "defective" card.used it for some time.one fine day it got blown when i ran crysis . called dell, they replaced the mobo. i ran few games and the temps ran over 100C in just 5 mins .so it means they replaced the defective non-functioning GPU with another defective one! can i sue dell for this? why the hell they replaced it with the same defective batch of GPU??
