Hello i bought i new Intel Pentium 4 2.4ghz 478 socket and a new heat sink and FAN. I installed them last night turned the computer on and nothing happens i can see the fan COME on but nothing is on the screen. What's the make/model of the computer?

Why did you install another cpu? Was there an apparent problem with your system before that? If so, can you describe the problem?


Did you disconnect any cables (are all cables in place?)

Did you add a LAYER of thermal grease to the cpu, before placing the heatsink on top?Its a systemex celeron 2.0 ghz system with windows xp. The motherboard is foxconn model # 651m03-g-6l and yes i put themel grease on before putting the heat sink on. The reason why i was changing it is because the fan stop on the heat sink stop working and burn out the cpu Can you see anything on the screen at all? Can you see the bios screen after the power button is first pressed?




I get nothing at allI do not have a answer but could it be the CPU got hot enough to damage the motherboard as well?Next thing I would try is checking the "J3" jumper on the motherboard next to the cpu socket... If the jumper pins are not connected together, then find a jumper pin to short the two pins together, and try booting again. If the pins ARE connected together, then remove the jumper, and try booting. Opening or closing this connection allows for implementation of different versions of the Pentium 4...



If this doesn't WORK, power off the computer and unplug it from the wall.

Open up the computer and touch the chasis, or some piece of unpainted metal to discharge static.. Remove the cmos battery for about 30 seconds and reinstall it. This board allows for overclocking and when your other cpu FAILED, the old bios settings were kept and the so the board may be stuck at a speed unstable for the new cpu....Removing the battery will restore the bios settings to default

Power your computer back on and see if it boots this time. It may take you straight to the cmos setup interface where you'll have to re-enter the time/date and you'll have to reset other settings as needed..
