You've already spent far more time than the eBay ones are available for, in 
terms of cost.  I'd guess this problem is most likely a motherboard issue.  
Find a similar laptop, throw your hard drive and memory in it, and I'll bet 
your problems go away.  It's not likely anything you'll track down beyond 
that, as it's probably a loose/cold solder joint somewhere on one of the 
boards or a capacitor that is working properly only under very specific 
thermal conditions or something that will otherwise require a new motherboard 
anyway.  New laptop on eBay will have that and more, in case you lose a 
keyboard, or screen, or the hinges, or any other things that can go wrong on 
an old laptop.
