Default HP dv7-1135nr Issue

Hello,

I am new here and wanted to obtain your guys input on the issue I am having with my dv7-1135nr. I got this laptop back in 09, and roughly 8 months ago it started randomly shutting off when it clearly had battery life left. The temporary fix for that was to unplug the battery, hold down the power button for 30+ seconds and it would work fine again. The only time the laptop wouldn't shut off randomly is if it was on the charger. If it was off the charger below 50% it would shut off randomly. I also noticed that my screen was fuzzy if you looked really hard at it. I figured the graphics card was going out on it. Eventually about 2 months ago my battery charger stopped working completely and I had to use my girlfriends. After that happened my battery stopped holding charge as well and the laptop let me know it needed replaced. Then finally yesterday when I went to turn it on the fan kicks on for a second and all of the lights pop up but it wont boot at all, not even to the windows splash screen / BIOS. From reading a ton of information online, it appears that these HP dv7's have motherboard issues from overheating. My question is there a cheap way to fix this permanently and is it infact the motherboard that's bad? It honestly doesn't seem worth it to replace with a new motherboard either since I could just get a new laptop cheaper by the time I replace the battery, charger, and motherboard. What is the initial reason this occurs?? Here is a spec list of my laptop as well.

A lot of laptops & PC's have an average shelf life up to 3 to 4 years....
Time to buy a new one.

Is it pretty much just scrap then? I tore the whole thing down to the motherboard. Is there a demand for any of the parts do you think? Or should I just put it back together and get the 80 dollars out of it? What caused it to fail do you think? Overheating?

Another question I have to, is how do you know which motherboards would fit this DV7 case? The Model Number for the motherboard that came with it is 486542-001, but how do you know which ones would fit if you were to order them off of newegg or some other site? I understand if I buy a new motherboard that I will have to get new ram depending if it's DDR2 or not. I am just curious how you are able to know if stuff can simply be swapped out or not.

Let me post the items of value which will (should be) standard across many laptops, assuming they are working correctly.

Processor - If it is removable
RAM
Screen
Harddrive
Disc Drive
Heatsink can be sold for a very small amount as it's copper

If it is a few years old I doubt you would get new parts for it, the vendor would only know the parts info....
Even if you could get the parts it will probably be too expensive to repair.
