Anyone know if there would be any problems if I upgrade my Z61m to XP Pro 64bit. I want to take the ram out of my dying Toshiba laptop and put it in the Lenovo. I have 4Gbs of ram I want to add. and XP home wont recognize all of it unless it is 64bit. Thoughts, Ideas?

A couple of issues here...
a) Z61m is not able to utilize all 4GB due to a chipset limitation, nothing to do with OS. The BIOS will "see" 4096MB but the machine can only utilize 3GB.
b) Unless you have a Core 2 Duo CPU (not all Z61m units do) in there, 64-bit OS of any kind is a no-go.
c) Lenovo never supported a 64-bit version of XP, so good luck finding drivers. That will be no fun, I can guarantee you...
That being said, Z61m is perfectly happy with standard XP, or even Windows 7 in a 32-bit guise.
