Laptop screen goes black
I just got a new laptop yesterday and I already found a problem. The internet works fine when i go on normal websites but when i go onto media streaming websites like Youtube or Globaltv my screen goes black but the computer stays on and I have to reboot by holding down the power button.
My computer has McAfee antivirus and i thought maybe it was it's fault but i turned it off and the only site that worked was Youtube.
I also thought it might be a driver problem but the Dell website doesn't have any drivers for my graphics card and i don't know where else to get them.
please help me
P.S i have a Dell Studio 15 with a AMD ATI Mobility Radeon 4570 1 gb graphics card
