Bad grounds can affect everything. If it acts up and you have a voltmeter, connect one lead to the positive cable and start with the other at the negative terminal. Check the engine block, body, frame (if separate) and other points on the car. When you have no ground there will be no current reading (or a very low reading) on the meter. Otherwise you should get close to a battery voltage reading.
Printed circuit boards can get bad connections too, they can usually be spotted with some decent magnification.
