The above services will be down until some time Saturday evening. This machine has been unstable and getting increasingly so. It does have a heat issue which I will resolve when some new heat sink compound arrives, but even down clocked so it did not get too hot it was still crashing and sometimes when almost entirely idle.
When I got it back at my home to work on, I discovered the ATX power cable was flaky, and I could make the entire motherboard lose power by just wiggling the cable. This is probably introducing noise and unstable voltage to the CPU.
I have ordered a replacement cable and it should be here Saturday. There may be other issues but a bad power cable is definitely an issue so I will start by replacing it.
