I suppose no aircraft flying overhead with ECM jammers on full blast
Ok joke aside, since you are having such a variety of STOP errors, maybe your motherboard's the piece that's gone cranky. That's real difficult to verify unless you have a spare motherboard of the same model, though.
In a previous time (out of so many) long gone, i had to go through 3 motherboard switches for a problem that wasn't directly with the motherboard, but an ultra isolated case of CPU-motherboard incompatibility. The CPU worked all fine on another motherboard,
and other CPUs worked fine on that motherboard. Oh the years of pain until i actually discovered that.
