The computer is an ASUS A7V600-X Sempron 2800+(2GHz) 768mb of ram and a NVidia 5500FX 256mb video card.
I'm having troubles when I try to play games that feature 3d graphics or even while trying to see videos on youtube, the computer starts making weird noises in the speakers and crashes. I tried using the computer with another hard drive, nother video card and different RAM sticks with no avail.
Anybody knows what is up with it? I'm out of ideas.
