I have this old Windows 2000 computer without a specified brand name. On the bezel it says "NSpire Systems" but the PC doesn't know. Anyway, I had to press the RESET button 10 times in order for it to turn on. When I unplug ny 7-port USB hub when my computer shuts down my computer turns on. Sometimes after it says "It is now safe to turn off your computer" i hold the button in for 5 seconds, release, and it turns back on. When I get into the BIOS Screen, it says "CPU is unworkable or has been changed.". Something wrong with my PC? Too much info?
