32 or 64 bit

How do i check if my CPU is A or B bit's

CPU make and model? You should be able to find this information on the manufacturer website (I assume Intel or AMD).

If it's an AMD chip bought later than 2004, then it's 64-bit compatible. If its an Intel chip bought after 2005, then it's 64-bit compatible as well. There's no need to investigate compatibility, as 64-bit chips are backwards-compatible with 32-bit software.

Welcome to the forums!

You can either Google your CPU or use CPUz to locate that information.
If it is a somewhat current CPU, it most likely supports x86-64.

Unless you have a Pentium 4 or a Athlon XP, it is 64bit compatable. It using AMDs x86-64 or Intels EXT64 which means it can run both easily.

For the most part true however the later versions of the P4 (late model Prescott's, Prescott 2M, Cedar Mill, P4D) do support x86-64 while the newer Core Microarchitecture (AKA Yonah) does not :/
ALL AMD CPU's Athlon 64 and newer support x86-64 (renamed AMD 64 in these cases).

Odds are that, if the computer was purchased 2006 or later, it will support x86-64.
To be certain, however, use Google or CPUz to check.

Well I meant Pnetium 4 itself. From what i remember Prescott 2M+ was labeled Pentium D.

But still, you are right. Anything 2006+ should be x86-64. Unless you got it from a cheapo place like one guy I know who paid $700 for a Pentium III based Celeron PC in 2006...... Poor guy got ripped bad....

...From what i remember Prescott 2M+ was labeled Pentium D...

The Pentium 4 D was Intel's first Dual Core offering.
Similar to their Core 2 Duo/Core 2 Quad strategy, the Pentium D's used a pair of standard Pentium 4 dies in a single package.
I believe the 90nm Smithfield P4D's used a pair of late model Prescott Cores (where x86-64 really enterd, edited above) while the later 65nm Presler's used Ceader Mill Cores.
As Hyperthreading was not supported on the P4D's until the 65nm generation, I do not believe the Prescott 2M was used there.
With all the different cores and updates Intel carried the P4 line through, it gets pretty confusing

Ugh
That guy really got riped
This is a good example as to why people who know less than nothing about computers should stick to Dell.
While a $700 Dell would probably be a rip off for anyone who knows how to build their own, it is certainly a better deal than a Mom-n-Pop scam shop special.

Not entirely accurate. I bought a new Dell Core Duo laptop in spring '06 and it is most definitely a 32-bit processor. Perhaps the OP should tell us his CPU.
