It looks like
that problem I was having earlier was due to the computer possibly overheating. I looked inside the CPU case and found that the case's fan was only set on LOW. So I put it on HIGH and I'm seeing how it does.
I still want to replace the fan on the motherboard itself. It makes just enough noise to discourage me from writing very long documents.

PS: I forgot to cruciform my phalanges and apply knuckle to dead cellulose matter in noisemaker fashion. About an hour after making this post, I had another Stop Error. I suppose I need to take this compy in for a service.
