how do i know if i need to upgrade anything else if i want to upgrade my processer. (video card, etc..)?

If you want to upgrade your CPU you need to know the socket of your motherboard and make sure you are getting the right one. Make sure that you power supply has enough power to support the new CPU. So basically you just need to make sure that you motherboard has the same socket as you CPU.

Well, according to your posting, your mainboard supports Socket 370 with a max CPU speed of 733MHZ. If your processor is less than 733MHZ, consider going up to 733MHZ. It should be fairly inexpensive and you'll be able to use the rest of your components. Pop out the old CPU, put the new one in, some thermal grease, and finish with the heatsink and fan. Your computer should boot normally and hopefully, you should notice a difference in speed.

Check the manufacture's website for a BIOS update. There might be one that when applied, allows you to use a faster PIII processor and more memory.

If you're considering a CPU faster than a Pentium III, then you would need to replace your mainboard. Check the specs on the new board to make sure your graphics card will work on it, otherwise, you'll have to invest in another one. Check to see if your memory (RAM) will work on the new board as well.

If you do end up replacing your mainboard, then you'll have to re-install your operating system. Back up your important data just in case something goes wrong.

Best thing to do is evaluate your needs. How much processing power do you require? Once you have that established, start with the processor, then the board followed by the memory, video card, hard drive, optical drives and other peripherals.

you don't need to upgrade anything other than the motherboard - depending upon which processor you choose. CPU is independent of RAM, hard drive, video card, and everything else aside from the motherboard.
