If your computer is noisy, runs slow or is getting very hot it might be caused by excess of dust and fluff accumulated in the air ducts, radiator or fan of your computer, the thermal paste between the processor and cooling plate might also be old, hardened, crispy and not conduct heat efficiently enough.
I can take your computer apart,, clean it inside and replace paste on the processors so your system will run faster, cooler and quiet again. It is just phone call away.
