Computer CPU Problems?

I in recent times installed a brand new socket 478 3 GHz 800Mhz FSB CPU surrounded by my computer and I'm having problems. When I turn the computer on, adjectives the hardware kicks on but the monitor stays sour and I don't get a sound the horn or POST results. Everything is plugged in and the heatsink is situated other over the CPU and the CPU is in correctly. I installed a contemporary video card but it did this with the antiquated one too. Any tips?

Computer CPU Problems?

Make sure that you, or anything else, didn't touch the bottom of the CPU or the place where it go. It could completly ruin it if you did.
your board isnt POSTing, swap out the CPU with particular good hardware and if it POSTs than you enjoy a bad CPU or the CPU isnt compatible next to the motherboard your using.
Push the on button on your Monitor. If that doesn't work, take it within. 1-800-GEEK-SQUAD
Are you sure your mobo is set to run at 800mhz fsb and not 1000? That would be the biggest problem for you and it WOULD do what you are describing. Second, did you set your jumper pins (if your mobo is that type) correctly for the modern CPU as well? Did you install the CPU itself surrounded by the correct orientation where on earth all the pins are settled within correctly? Is your mobo even a 478 pin style?
revert to the old CPU, if it works the error is beside the CPU send it fund
this happened to me too

if you want, you can resign from the computer open and turn it on

next, after a while, touch the heatsink

if its hot, then the CPU is probably working all right and the problem is somewhere else

if not, you any have a desperate CPU or you didnt use enough (or any) thermal gel between the CPU and the heatsink
