The binbag murders are back on!
After using hughanchor for most of the weekend, I was powering down, when a blue screen popped up with a page_fault stop error. So, it looks like the problem is not yet cured. I've ordered a replacement motherboard, since this is now the only remaining culprit, and I'll swap it over when I get time. May not be for a while, the board is unlikely to show up before the quaint "Thanksgiving" holiday they seem to get so excited about round these parts, so it'll have to wait till later in december.
