    I have found sites that list compatible CPU's for my Mobo, but what I really want to know is what information is important? eg: if a CPU matches my Mobo specs for FSB, socket and any other crucial spec can I presume it will be compatible, or do I have to check a list from a chip supplier and be restricted to that?

You should try to find the manual of your mobo. Search the manufagurer website for the same model number. It usually lists all compatible CPUs.

Socket 478 is for Intel Pentium 4, Intel Celeron, Celeron D and Pentium 4 Extreme. But that doesn't mean your motherboard supports them all. You should still check the manual.

    You should stick to the supported CPUs for your mobo. And try to find the latest updated manual for that mobo so it would have an updated list of supported CPUs.

Replacing the heatsink,will it stop it from shuting down? if i use desk top fan blowing onto the inside its ok and works. i also have had blue screen come on

YES! The dissipation of heat is crucial. Thus making a heat sink / fan indispensable. That is most certainly the cause of the blue screen.

Furthermore, expect the system to fry in the near future without a working fan.

How to recognise a pin and pi nnless processor

A pin Processor has metal pins on the bottom of it.

For an example let's use an Intel Pentium 4 processor, that fit in a Socket 478 processor socket.

Viewing the link above, observe the green square under the grayish metallic looking square.
The green square is a circuit board.
(Width and length, about the length of your first digit on your thumb)

The grayish metallic square, is a metal shell cover over a Chipset.
Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The Integrated Circuit here is the Processor.
The Processor is connected to the green circuit board. (PCB. Printed Circuit Board)

On the bottom of the green circuit board are contact pins. In this case 478 of them. (478 pins)

The tiny metal contact pins fit down into matching socket holes, in the processor socket.

A Socket 478 processor socket,

(You can click on the photo to the upper right to enlarge it.

The next design to come out, has the Processor with contact pads, (Pinless), and the processor socket has the contact pins.
An LGA 775 processor socket,

Example of a Pentium Dual Core's bottom side. (LGA 775 processor socket is used),

There you have it.

A 'Pin' processor has metal contact pins on the bottom.

A 'Pinless' processor has metal contact pads.

I want to upgrade the current CPU on the motherboard to my HP Pavilion 760n.....what is compatible with?

Any Pentium 4 northwood or willamette CPU should work, when ordering your CPU make sure is for socket 478, you can use up to 2.80 Mhz speeds on that motherboard. you can get those on ebay for a good price.
Hope my opinion helped. :)

I have a gateway mvn 350 laptop with Intel Pentium 4 CPU 2,66Ghz/512/533 SL77M Malay. Now my question is, since sl77m is not available easily, is it compatible with other chips with the same 478 pin...

I purchased a replacement A/C power adapter for my gateway mvn 350 laptop. It hissed and would not power my computer. Today I have received a replacement;again the same problem occured. My current adapter is very worn and I will not be able to use it soon. Is the problem the adapter or the recepticle on the computer?

there is a basic guide i will give ya
1. not all parts are comptable so please check visually before trying to swap them

a. the large to med size board that everthing plugs into is the MOTHERBAORD or mobo for short
b. the cpu central processor unit (usually) is under a heat sink & fan upper left hand when looking at most (most) desktop mobos
c. the ram random access memory is usually to the right of that and may be sd ddr ddr2 depending on age of mobo
e. there should be cables going to the optical drive, cdrom, etc, hard drive or HDD for short wide usually gray is called ide or smal thin sata depends on the mobo
f. sometimes there are parts in the slots on the bottom left of the mobo (these can be anything from vidoe cards to modems to lans no way to tell without more info)

the first thing to look at if you are upgrading is the ram compatable take a tick out of the old unit you will see the catches make sure it is unpluged and you have touched the metal case before touching inside of computer static electrcity can damage a lot on a computer then take a stick out of this one do the slots or notches line up if so more than likley they are compaitble

next look at the cpu repmve the heat sink and fan carfully lift the cpu chip do not bend the pegs or its ruined look at the slotit came out of it will tell you mpg or pga 478 or socket a or socket 482 they would have to match to see if they were ubgradable.

like I said though depends on the age difference most are not that compatible even in the same brands.

Gigabyte mother board

hi reason y it wouldn't start is because the 2 is not compatible, what u can do is get a Intel P4 not a celeronD check the socket size and make sure that it correspond with the board that u have. The board that u have uses a 478 socket size so u need to get a processor with the same socket size ok... that should do the trick

Either your setting is not correct or your new AMD CPU is not a compatible type. One thing very easy to verify is if it is compatible, it will seat very firmly. You may need to check the model and serial number to be sure you get the correct CPU for your old board.

I have a Boot Problem with my INTEL P4 3.0Ghz. 800Mhz FSB,1M L2 Cache, Socket 478 CPU

I have experienced something similar with my new Core2Duo processor and a fairly new Socket 775 processor. Troubleshooting it led me to believe the CPU simply wasn't compatible with the motherboard. Although it's a shot in the dark, I suggest that you try out some of the following: - Did you try pulling out the graphics card to see if you got it to POST then? The graphics card or the monitor may need replacing. - Did you remove the RAM? - Are you sure all cables are attached properly? - Try to take out the CPU, talk to a friend with a socket 478 motherboard and replace his CPU with your CPU. Does it work now? If yes, motherboard needs to be replaced.
