But even i have update my bios from A11 to A14 teh pc dont work this i7 must work because he is compatible with the motherboard !
I dont know what is the problem !i need you help if possible .
You need to verify with dell that the i7-3770K is compatible with THEIR bios.
An upgrade processor must be socket, chipset, and BIOS COMPATIBLE. Just updating the bios is not an answer unless the bios supports the processor.
