You guys will never guess what the problem was. I reinstalled the OS and still got the crash using the "Gmail test". The only other thing I had installed at that point was my USB wireless internet adapter. I uninstalled the drivers and software for the adapter, hauled my PC to the living room and hooked it directly to the router with an ethernet cable. And I've had zero problems since. It's starting to make sense now since every time it crashed I was online. It turns out the drivers are for Vista-64 bit, tho they work for 90% of the things I did online.
Thanks again for the help. I'm considering this case closed.
PS My adapter was a NETGEAR WG111v3 USB adapter.
