Both of those errors relate to memory failure.
Check the easy to do things first. Unplug the system, and reseat all the memory chips as shown here. If that fails, try removing all but one memory chip. Try each one until you determine which chip is bad. The last option is that the motherboard may be bad in the memory area.

Thanks for responding to my question. I have had memory problems with my PC before. It looks like it's happening again.
