I bought a new GPU and it's not working on my computer... I tried with my old one and it's okay, and this GPU works in my friend's desktop but not in mine... When I try to boot the computer the fans work for a while and then it turns off, without any display... any suggestions?

I guess that your new GPU is a better one than your old one. But did you take a look at its energy needs? Are you sure that your current PSU can provide your computer with enough energy for all the components to work? I guess that a weak PSU may be the reason. You should also check the temperature and make sure the fans are well-applied, if the temperature is too high on either GPU or CPU the computer will turn off to prevent any damage.
