Faulty PC

:wave: First time here. hello, guy's my name is alex.

I have a dell and i installed a 1 tb hd and then tried to boot, but no sound. And the cpu fan would turn for 2 sec's and shut off, the monitor would start to come on but shut off. I checked all connections and only removed hd. well found someone on craigslist that checked it for me and said it was the processor?
could that be true?
And also on a different pc, is it bad to have a cpu on a motherboard that is to fast. this guy said the cpu is to fast for it. Any comments would be appreciated.

Thank You all. alex from council bluffs, iowa..
 
It would be very, very helpful if you could give us the hardware specs including make and model. How old is this system? Can your motherboard handle a TB harddrive, particularly the BIOS?
