What processors can I upgrade this computer with?

That would be a question to put to the supplier of the upgraded parts, try www.newegg.com

you can install any socket 775 cpu.
core 2 duo or more.

I would suggest that you should try to buy a new computer. We do have new Computers that has new processors that are much faster than a P4. :)

The processor upgrade defends on your motherboard if it supports a processor like Core2Duo, because it all depedns on the motherboard if you can upgrade processor and RAM ,if you buy a new processor and its not supported by your motherboard it will be a wast, but if your computer manufacturer told you that your motherboard can supports a processor like Core2Duo go ahead upgrade to it , that will definitely make teh computer faster and better sicne Core2Duo is a high end processor right now..

Hope that helps...........

When you're running an average load, start Task Manager and view the performance tab. If the amount of free RAM is low, then definately upgrade your RAM. Plus, nowadays it's really cheap to upgrade ram.
As far as upgrading your processor, that can get a little tricky and expensive.
Also, what do you mainly use your computer for, and what operating system do you use?

Sounds like the processor you're trying to upgrade to isn't the same frequency. The processor, motherboard, and memory have a matched frequency. For example; a motherboard with a frequency of say PC4200 will only accept a processor and memory of a PC4200 frequency. If you try to use PC5300 memory it basically won't do anything, blank screen, or maybe a beep. The same if you tried to use a processor with PC5300 on the PC4200 board. The best way to find the frequency rating is to look on the memory. They class the memory by frequency, but rarely ever list the frequency for the board or processor. Research the new processor to find out the memory class and then see if it matches the memory in your machine. If it doesn't then the processor won't work. If it does, then new processor may not be compatible, and that means more research.

you should upgrade computers, because a pentium 2 and 3 wont do ****.

As your processor is very old, to buy an upgrade would be more expensive than buying a new computer. There are not many of the socket 370 type processors around, if at all. Your motherboard will not drive any of the newer processors.
