Windows XP 32 bit or 64 bit?

Thanks!

Thanks, but this information from the MS website does not answer my question. However, from the first respondent's reply, I am pretty confident that I have the 32 bit operating system.

Another way to prove this, is that you try to install in a PC with a processor that not support the x64 arquitecture, i mean, a x86 PC. What processor do you have?

The processors are Intel core duo 6400.

I purchased two computers from an asset realisation. The computers have the Microsoft sticker and an OEM Windows XP cdrom and nothing else. One computer has a g33M-s2 motherboard while the other has a ga-vm900m rev 1.

I have now downloaded the drivers for each of these motherboards from the Gigabyte site, and, given your earlier advice, have selected the 32 bit versions.

The driver cdrom did not come with the computers.

cheers and thanks

Ok, so, the CD are 32bits.
