Log (most recent first)
- RIFA film capacitors in PSU replaced, they're notorious for failure after a long time. PSU still does not seem to provide rails. Fault in other components?
- Floppy seems fine, fault is in PSU. While diagnosing, got single arc in some PSU component. Does not boot, does not provide rails.
- Discover that disconnecting floppy allows boot to BIOS, suspect fault there causing overcurrent
- Does not boot, squealing/chirping noise, manual indicates short in a component
- Initial boot(s): HDD error of some sort
