This is why you get a UPS battery backup or at the minimum a surge protector.
By 'the monitor comes on' what do you mean? The power light? or do you see something on the screen? or just a flicker?
When it did work for your husband did the system boot up to windows?
Did you try pressing the monitor power switch? does the monitor stay on if you hold in the switch?
Power surges caused by lighting can damage your system, monitor could be fine other things could be wrong.
