advice for a new CPU and steps to replace old CPU

[kwfine]

Hi all,

I wanna buy a new CPU to replace the old CPU of 933MHZ of my old PC,
but I don't have any experience on this task before.

Please advise me.

youll need to know what socket your old one is and what cpus your mother board supports both can be found in the mother board manual or if you need to look around on the motherboard and find some numbers and start typing them in on google and see what you come up with

I am sorry, but I just don't know how to check what socket my old MB is and what CPU type it supports.
I just have the model number of the CPU socket: mPGA478B
Its manual was lost , BTW.

Replacing the CPU is very easy. It will only fit one way.
The toughest part is to remove the CPU Fan.

1. Remove the CPU Fan and CPU
2. You need to clean the thermal paste on the fan.
3. Insert new CPU into the socket
4. Put a tiny grain of thermal paste onto the CPU.
5. Fit the CPU fan on the CPU.

Be very careful with the cpu fan clip. Many years ago I saw my colleague broke the clip on the mainboard while removing the fan. There's no way to fix it other than sending it back to the manufacturer.

If you can provide the motherboard's make and model number, (definitely printed on the board somewhere) I'm sure one of us reading this can dig up some specs for you, as to how far you can push your motherboard, CPU-wise. I'm curious though, are you positive the current CPU in the computer is only 933 MHz? It looks as though that socket setup was used not so long ago, when average processor speeds were considerably higher than that. I'm no expert in this field, but from what I find on the net about that socket, the information doesn't line up. Could be true though!

Anyway, make and model of the motherboard are pretty essential when it comes to determining exactly the CPU that would be 'the limit' for that motherboard. Also, is your system a brand-name computer, like a Dell or something? Just wondering.
