Part fails on one computer but not another computer.

I have a large part I'm working on 300+ features. 15MB.

Work Computer: I7 2.8GHZ 8MB RAM Nvidia NVS 4200M

Home Computer I7 4.5GHZ 16MB 1866mhz ATI V5900

Cntrl Q @ work works ok.

Cntrl Q @ home crashes the part.

Same SP on both machines.

Ideas?
