I bought a socket 478 Intel Penitum 4 3.0 GHz / 1M / 800 SL7PM CPU for my computer and after replacing my 2.0A ghz 400 P4 chip my computer shuts down after being turned on. Then I decided to place the 2.0A ghz P4 chip back in. The computer seemed to power on normally, but then it shut down again. Can anyone help me?
I have an ASUS P4S800D-X motherboard powered by a 500 watt power box. I have three sticks of DDR ram (1) 512mb, (1) 1gb, and (1) 256mb stick.

Initially it sounds like the hsf is not seated properly. how far does the boot goes before shutting back down? does it make it through bios and into booting windows before shutting down or does it make it into windows befoer shutting down.... Good contact between cpu and hsf is when after spreading thermal past and installing the sink... if you were to lift the sink... the paste should be almost squished out... having a very consistant film across the heat spreader.
next.... if you are sure that you have good contact with the HSF..... try unplugging components you dont need to bring up the system... like memory dimms... run with only one... unplug extra hdd and opticals not needed... maybe even add-in cards.. basically reduce the amount of power needed from the psu to bring up the system... it might be a case of you had your psu for such a long time that it is worn out and that by putting in a higher draw cpu that may have just put your psu over the edge from once working to a non working situation. try this out and see if there is any change.
with that minimal configuration.... try installing the newer cpu to make sure that the system can boot into windows and that the new cpu is working.... then try each of the Dimm individually to make sure than not one of them are bad... then at this point... you can either 1. add each component one at a time in to see how far you can go .... or 2. buy a new psu... personally I would make sure you newer cpu and the rest of the dimms are working individually and then get a new psu.
I have looked at your mobo's manual. The BIOS should detect and automatically the CPU and memory, there is no setting to change. The problem you are having is compatibility issue. I am incline to say it is your CPU from my past experince. Good Luck

plus i cant believe you bought a prescott 478. you coulda bought my old rare HT northwood core 3.4!
True - You can also flash your mobo BIOS. If it is an Intel mobo chances are they will have an update (BIOS) to support the latest P-4 (478 socket) processors .
On a side note - My gf's Gateway computer can support a Prescott but Gateway has the BIOS locked....I can't flash it to the latest BIOS for a Prescott...stuck with a Norwood and 1/2 MB of cache
you do realise that the northwoods are better than the prescotts. prescott is probably the crappiest intel redesign this decade. a terrible bodge job, finding on average less than 10 percent more performance than the northwoods for in many instances up to 40 percent more heat! FORTY percent. which means that the 478 northwoods were the 478's to have, they killed the prescotts in average use and for overclocking. northwoods as anyone who looked into the situation at the time were the chips to be sought after. thats why my northwood is still worth some money as a rare hyperthreaded @ 3.4ghz, while the p**s poor prescotts are ten a penny
