I'm having some problems with a Quadra 660av I left unused for a few months.
When I turn it on, it crashes after about 15 minutes of use. Sometimes it simply freezes, sometimes I get an error message ("bus error" or an other one) with the "restart" option (clicking restart won't change anything). After such a crash, it won't usually reboot, or if it does, it freezes during startup (sometimes with an "invalid instruction" message). If I leave it unused, it will eventually be able to reboot.
What I tried : change the memory, reformat the HD, change the HD, change the SCSI cable, reinstall the system (OS 8.1), install an other version of the OS (7.5), zap the PRAM, unplug the AC and the battery.
The specs : Quadra 660av, 68 MB of RAM, 18 GB SCSI HD, 50 mhz Quaddoubler instead of the original processor (and since I don't have the proper tool, this one will be difficult to remove).
Any idea?
