NEVER REMOVE ANY COMPONENTS WHEN THE COMPUTER IS ON
Have you tried to overclock the processor ?
Shut the pc off, take it both sticks, pick one and put it back in to slot 1, be careful with white clips that hold the memory in place.
Once you have done that, restart the pc and when you get that message again, press f2 to load default settings, then press f10 to save and exit bios.
When machine starts run mem test on the single stick of ram.
