- I have a no-name 486/33 motherboard that has run flawlessly for 7
- months. I left the computer on when I left the house at around 11 AM
- today and when I got back at 4 it was dead. No raster on the monitor, nothing.
-
- I powered off, waited, and powerd up again. The three LEDs on the
- keyboard come on and stay on, and the HD drive emits random "clicks."
-
- I pulled the power supply and checked the voltages at every connector:
- all OK.
-
- I put the power supply back and checked the bus voltages between B1 and
- B3, B5, B7, B9 and B29: all OK.
-
- I pulled all boards but left the 5/15V power connected to the HD and 2
- floppies. Same clicks from the HD and still no raster. Ditto after I
- reinstalled the VGA card, and also after I swapped it for a spare VGA
- card.
-
- I even tried disconnecting the keyboard to see if the response would be
- better. It wasn't.
-
- Sounds to me like something on the motherboard has gone belly up (don't
- say "the 486", please!!). What do you think?
-
- Thanks,
- Pete
