So it pretty much means that the motherboard or cpu simply failed, and given their age I'm going to have to replace both. So then I go online to look around at hardware, since I haven't kept up to date since I got the core of this machine 4 years ago. It looks like even the IDE drives and AGP card are going to have to go if I don't want to limit myself for future expansion.
I mean that wonky computer finally dying isn't too unexpected. I'm glad that at least it isn't some hard drive failure in a few ways, but this is one of the last things I need in the middle of a lengthy job search.
Speaking of which, I'm supposed to hear back about my latest interview tomarrow. Maybe this is just pre-emptive karma...
As for AGP, it's dead. Sorry.
