    Clear the PRAM and NVRAM.
    Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

    My computer doubles as a space heater.

    Permanently Retired Systems:
    RIP Advantech UNO-3072LA (2008-2021) - Decommissioned and taken out of service permanently due to lack of software support for it. Not very likely to ever be recommissioned again.
    Asus Q550LF (Old main laptop, 2014-2022) - Decommissioned and stripped due to a myriad of problems, the main battery bloating being the final nail in the coffin.


    Kooky and Kool Systems
    - 1996 Power Macintosh 7200/120 + PC Compatibility Card - Under Restoration
    - 1993 Gateway 2000 80486DX/50 - Fully Operational/WIP
    - 2004 Athlon 64 Retro Gaming System - Indefinitely Parked
    - Main Workstation - Fully operational!
