How can I check for dead CPU?

[NinjaMuffinz]

Hey guys, first off, sorry if this is in the wrong place.

I've just built a new budget rig. Bought all new components except my CPU (AMD Phenom II x4) and when I fired it up. All my case fans spin up, my CPU cooler (H60) spins up, HDD spins up, optical drive spins up and I can open and close the tray. My HD 7770 spins up, however nothing comes up on my monitor. No motherboard beeps, nothing.

I've tried using different RAM in different slots, tried a different graphics card, still the same. This leads me to believe that it is either the board or the CPU. The CPU came out of my old board that went bang. Is it possible that when the old board blew, it took the CPU with it? Anything I'm missing? Is it worth me ordering a new CPU?

All the cables are connected and everything is seated properly.

Thanks for your help guys and gals

take the cpu out and try booting then, the mobo should beep about a lack of cpu if the mobo is good if it doesnt the mobo could be the problem

I'll give that a try, thanks! Also, whilst I'm here. My motherboard didn't come with a speaker in the box, am I safe to assume it's built in?

Thanks for your help

wouldnt like to say for certain, some are some arnt, that test is in no way certain that its the board, they have startup systems that check this then that then the other but if it can identify that there no cpu maybe then try pulling the memory or something, the manual should hopefully give a startup guide as to what order it checks stuff in and what each post beep means

Thanks for your help man! but the problem has seemed to have just gone away. I tried to boot it before I took the CPU out etc and it just started up. Going to chalk that one up to the PC fairies I think

You should never turn on a MB without a CPU installed. I did this once to a small firework show and a subsequent dead board.

yea, starting a motherboard without a CPU is a bad idea. as you said, if its a good board it might detect it, but if it isn't, its going to be a door stop afterwards.

OP, sounds more like a GPU was the problem. CPUs almost never die. if it doesn't arrive DOA, and you don't put silly volts through it, its going to last 15 years unless you're very unlucky.

was there a speaker attached to the board?
