I think I have some bad RAM on my computer...I remember seeing a program here that will allow you to scan and check your RAM, but I can't seem to find the link for it. Can anyone help me?

Memtest86
Go to the Downloads page, and download Memtest86 v3.3 ISO image (zip), to create a bootable CD.
See this tutorial for directions on how to do that:
