Is my computer 32 bit or 64 bit

I am intending to buy a new copy of Windows XP Pro. My existing copy works well enough, but fails validation despite it being a genuine version. I dont know if my system is 32 bit or 64 bit. According to my system device manager I have two Intel(R) Pentium(R) 4 CPU 3.000GHz. My Motherboard is an ASRock 775VM800.
I have looked at the literature with my computer but there is nothing specific re 32 or 64 bit. Is there an easy way to find out which it is.

run cpu-z click here and post the results of your cpu.

Have you been in touch with microsoft, personally, to try and validate your version of windows?

Rather than spend money on a new copy of Windows, have you tried to validate by phone. The validation process gives you a number to ring and tey should be able to sort out the problem for you.

Sorry ed-0 - didn't see your last para until I'd sent off mine.

I have run CPU-Z, but the results exceed the characters permitted in a post. Which results should I post?
I have spoken to Microsoft they say it is OEM and I should contact vendor. Vendor has gone bump.

If you have the COA sticker on the side or back of the computer with the genuine keycode on it,Microsoft should give it the Ok if you phone them,

I have two Intel(R) Pentium(R) 4 CPU 3.000GHz.

will run a 64bit opsystem

I have phoned Microsoft and they isist the matter is "Not within the Microsoft frame of reference" As my vendor is no longer in business they say I should purchase a new Retail version of XP Pro. I don't want to, but what can I do?
The question now is: Should I purchase 64bit or 32 bit? Will my existing applications run on a 64bit or would it be more prudent to buy 32bit.

My details are:

the 630 Prescott is a 64bit cpu, you have a 64bit motherboard. So you should be able to run a 64bit operating system.

Still think it worth try microsoft re validation or if you have to buy, why not go for vista?

I would not have thought it worth going 64 bit unless you also have progs that are 64 bit and I would be surprised if many were. I expect your system works ok with the present 32 bit win xp so 'if it ain't broke, don't fixit'
