I replaced all leaking capacitors about 4 months ago. I cleaned it out the board tediously.
Every-time I switch on my old computer it is stuck on the menu screen. The machine does not respond to the keys I press. Even the clock is frozen on the screen.
Holding done CTRL, Break and Reset 20 times does nothing to break out of the freeze state. Turning off the memory switch doesn't work either. It was working fine for 4 months.
How do I break out of these lock ups? What's the likely culprit to the lockups?
