Welcome to Techspot!
How dust and moisture free was Storage.
You might need to do a real good cleaning in that box, clean & reseat teminals, etc.
For sure put in a new CMOS battery.
 
thank you, will give that a shot and see if that fixes the prob. will let you know one way or the other. didn't get wet as far as i can see but storage units have a 3 inch gap at top of walls between units so got a little dusty.
