This thing is happening to my dell vostro 2520 frequently that whenever doing any normal tasks, the screen looks like it s getting hacked like in the movies and makes a really weird sound. And it wont read my 2nd stick of ram which is a stock dell 2gb, in slot one i have 4gb kingston hi speed ram.
Just downgraded from windows 8 to 7 ultimate. The Laptop has a pentium 2020m with 500gb hdd.
It would be awesome if somebody helped.
Thanks in advance.
