Hello,
A couple of weeks ago I dismantled my Alienware m17x R3 to add more RAM. Since that time i didnt see any improvement in performance of my laptop and things got even worse. I started to have 90%-100% CPU usage when watching streams or videos online and also playing some low requirements games. Recently I downloaded a program to check my temperature of cores and it goes up to 90 degrees with 80 being normal while watching streams. My cpu is intel core i7 2630QM with 2GHz speed. I have a friend with the same CPU and worse graphics card, who can play much better games and his usage of cpu doesnt exceed 20% when doing same stuff as me (friends started saying my computer has AIDS, but no one knows what is truly wrong). I can hear my fans working so I dont know what could I have damaged in my laptop. Please help
