I took a look at your profile first and you show owning a Dell. Though plenty of socket 478s are still out there, putting one in a Dell case might be a problem. Is this the PC you are speaking of? If so, the task of replacing the MB becomes more complicated. As I said, socket 478s are plentyful. Most of these should support your processor if it's working ok. I won't offer specific recommendations as that depends much on what you want to do and what features you need. As for myself, I like ASUS boards.
I have a feeling that you ppl may LOL so hard cos the stupid question Im going to ask. Its okay to LOL cos I can take it! LOL! Okay, I have a 2.4P4 533FSB Northwood, I need a new motherboard. Does any motherboard accept this CPU if it states "Supported CPU, CPU Socket Type Socket 478, CPU Type Intel Pentium 4/Celeron, FSB 800/533MHz, Supported CPU Technologies Hyper-Threading Technology"?
As you can see I dont have any clues about PC's. So go ahead and LOL im not watching! LMAO!
Always LOST in space w/o my CNET buddies out there to save me!
