I have problems with my Apple II's about once every two years.  I
found
a great fix.  Problems include crashes while booting, not booting, and
corruption of data.

I take all the cards out and clean the gold plated contacts with
rubbing
alcohol and a cloth.  Get all the black off and polish it a nice gold.
 I take
out all socketed chips.

The focus card gets it's drive removed and reinserted.

I use a compressor to blow the slots out.  Compressed air cans
work good too.

I then take out my can of electric contact cleaner.  It is meant to 
remove corrosion from motor brushes.  I tested this a long time ago
and found it did not eat any plastic, enamel, or components.



I spray the slots, chip sockets, and motherboard with the cleaner.  I
wipe the motherboard clean.  I let it sit a few minutes and use a
compressor to blow
it dry.

Stick all the chips and cards back in, and I won't have problems for
another
few years

Some cards may work fine in a slot and not others due to dust and
corrosion.
This makes some of the pins not contact correctly.  Different cards
use
different pins so some may work in a slot with certain dirty pins.

I'll look in the garage and post the brand name of the cleaner I use. 
It works great.
