You can reset the CMOS by taking out the silver circular battery (the CMOS battery). A little smaller than a nickel, and thinner too. There will be a clip to release it, not too hard to pry it loose.
Leave it out for 5-10 minutes, reinstall the battery, make sure it is seated. Then reboot. Plug And Play stuff will be recognized by the system, other stuff may need to be changed manually. Have you configured your (a) BIOS before ? You may need to tweak some. Not too bad.
Couldn't it be a ram issue or something?
I guess it could be. Not sure, but you could try running Memtest86. That seems to help people when testing RAM. I haven't used it personally.
