Will a pc boot if the processor is not in correctly?

ok so i have just finished building my own pc, w/ intel core i7 and a p6t6 ws revolution motherboard, i am still waiting for my graphics card and finished building the system so i turned it on to see if it would start, my question is would the pc start if the cpu was in incorrectly or does the bios just run off of the mobo, my motherboard beeps when it has something wrong and it does 1 long beep 3 short which means no vga (i expected this since no graphics card) and then it does 1 long beep 4 short which means Hardware component failure, does that mean that the graphics card would be counted as both or did i put in the cpu wrong :( , the gp diagnostics card says 00 which means "Leave BIOS and p control to OS" which makes me think it's not the cpu but i don't know
