MacBook Pro restarts when I press Command and a button

I didn't notice this problem until yesterday, and the only thing that has changed on my computer is that I installed new memory.

I was doing a shortcut for copying and pasting, and when I clicked CMD and C, the computer restarted. I lost my data on that document. WTF.

Anyone else had this problem?

Here are the only details I can give.

Early 2008 15" MacBook Pro

Installed 2GB Samsung PC2-5300 DDR2 SDRAM module making it a total of 3 GBs three days ago. Didn't have the problem before then.

I am writing a document, and I press Command C or B or copy or bold or whatever, and I kinda pressed it hard. The computer rebooted and I lost the document. It doesn't shut down and reboot. It reboots like turning off a light and turning it back on. I have been able to duplicate the problem several times.

Since the memory module is right were the C, V, and B letters are, could the memory not be firmly placed in and therefore is coming out causing the computer to reboot like that?
