I am working on an AMD 486 DX4-100. When I first saw the computer, I turned it on and I got the 1 beep but nothing on the screen. The floppy and hard drive did not even try to activate.
No problemo, I took the entire computer apart, cleaned up an inch of dust so I could see the motherboard and proceeded to hook everything back up properly.
I booted the old gal up and . . . same thing as the first time. Not beat yet, I pulled out my trusty "Post Card", inserted it it and . . . no error code. I checked the voltages and all was OK.
It appears I am not even getting to the "POST".
Where should I go to next? BIOS Chip? Battery?, or Motherboard?
