Chipset short-circuit n5110

So my laptop had some issues lately after a regular cleaning disassembly , I say regular because I do it every 2-3 months 

First the lcd didn't output video , it had light on but now output , the Dell lcd self test thing worked properly so I said maybe the connecters got damaged , after replacing it the problem remained and after a short while all my USB devices started acting weird like turning on and off , also my chipset started burrning and after a short while the laptop shutdown because of over heating 

So, now all my study work is traped under the drive of a laptop that can't keep it up for 5 mins pugged in.

There is no marks of over heating or liquid damage on any thing 

Only the chipset burns , and it starts doing that when it's plugged

I know it may like seem like an obvious "NO" but:

Can it be just some drivers issues?

I also know that it's most likely a short-circuit, I just can't see the reason that happend.

I can't afford an upgrade for now so please no one say it.
