32-64 bits

THANK YOU ALL

Ummm, it says in your signature that you have XP Pro SP3 32 bit. Do you mean the Operating system or the processor? From what I have been able to find it looks like your processor is 32 bit only.

controllpanel > system

or if you have CCleaner installed it will show on top of gui when opened

thank you guys
