So, I have a 6-year old laptop (Toshiba sattelite l655-120) and after all these years I started facing a few problems. After trying to start it,the fan started spinning for 4-5 secs, no screen loaded, then it stopped and repeated by itself. I tried cleaning around and removing one of the ram sticks resulting to the pc doing the same thing but lasting for 10 secs. Now I can hear the hard drive spinning before shutting down again and repeating. What could be the problem? I have to state that I experienced gpu problems before all that with whole pixel lines not loading and not being able to get past windows loading screen without blue screeing! Is my gpu burnt?
