A friend and I were just discussing this earlier tonight. You could try
any live-CD of your choice for a memory test.
I found a thread for a hard drive test http://tinyurl.com/o3vmy7
while `true`; do mke2fs -c -c <device>; done I believe that will
perform a slower read/write test not sure if you'll be able to keep the data.
And you can heat things up a bit with... md5sum /dev/zero which should get
things pretty hot pretty quickly, so keep an eye on your temps.
Aside from that there are a few other threads I found searching over the
archives. http://tinyurl.com/ojnsce
