Having returned to Ilkley, I have the opportunity to investigate my strangely nonfunctional PC here. (To reiterate: the lights on the keyboard do dance in manner most unbecoming, and the screen it does remain blank.) Upon opening the case and experimentally activating, a likely cause becomes apparent: Processor fan no worky. There's clearly power going in - the fan on the graphics card buzzes merrily, as well as the aforementioned keyboard seizure - but there is no motion from the processor cooling unit until the power is switched off, at which time it jerks fanwise but once. To my A-Level Physics educated eye it has the look of a busted electric motor. Perhaps it is the alternator.

So the questions now are ... (a) Which bits of my PC will require replacement, and (2) how much can this reasonably expect to cost? I myself am quite unsure what knock-on effects this fan malfunction will have accrued; I suspect the processor will have performed a HACF^[1] but do not know what else this may have affected. As far as cost goes note that I'm not looking for bleeding edge, or even anywhere particularly on the knife; the current processor is 400MHz. It is required only to talk to the interwebs and back again. Stretford houses my game machine (lovingly constructed by

pkgem's SO).

I strongly suspect this will be something I will be putting off until I am once again gainfully employed. But I'm still curious...
