Bad 4GB Ram

[The Reason]

Ordered the 4GB kit from crucial a week ago, got it in today...

INstalled and worked great for about an hour, then froze up the computer....

Rebooted several time, and reseated the ram, but always after booting up, the computer would eventually freeze(usually about 2 minutes in)....

Works great with old 1 GB sticks in it, so, any suggestions before I send the ram back to Crucial?

Nope. You've done everything you could, like reseat the ram. maybe try a combo? put one old stick w/ one new stick and see which new stick doesn't work.
