Hello,

I hope that THIS PAGE will help explain what you need about the CPU.

I have read reports of users upgrading that CPU. But, these were all on non-Dell systems. I have no idea what the Dell BIOS will support as far as other CPU's.

The socket AM2 Athlon dual cores will work - that said, given the cramped case, poor ventilation and weak power supply - I would stick with the 65 W processors.  Using the higher-wattage processors just invites instability and early system failure.

I appreciate your help, but I have no idea what I'm supposed to get from that page. I know if I can upgrade my cpu it has to be an AMD cpu, but I need to that I can and which AMD processor (preferably alot better like a dual core) is compatiable with my Dell Inspiron Processeor 531s with Windows Vista Home Basic

As you intend to reuse the heatsink, plan on cleaning it's base and reapplying thermal compound to the processor.

Directions for cleaning and applying thermal compound, are HERE.

You only need a small tube of thermal compound, this can be purchased from any computer store.
