The desktop is running Vista Home Premium 32 bit - factory installed is my guess. Puck, it has 4 slots that hold a max of 2GB each...so could theoretically put 2GB in 3 slots and leave 1GB in the fourth.

It comes with 3.5 from the factory.

The problem computer is the laptop. Praying on that one! Leaving in 20 minutes, driving uphill in deep snow BOTH WAYS . Will post when I get back.

Thanks again all!
