Awesome! I have this exact computer mentioned (u57a bbL4) and am having the same problems you've mentioned, so I'm considering buying and replacing the motherboard. I noticed that there is a U57A k554 motherboard, not sure but is this an upgrade? Is there a motherboard that is an upgrade all the while fitting all of the other specifications for the elements? cpu, ram, hd etc? I am going to get a motherboard and a ssd .

Thanks for the info!

I am not sure about the U57A K554 being the upgrade to the previous one but since it has the same series it should not be a problem.
