Hey, can someone please help me with this problem. I just bought a nvidia XFX geforce 7600gt agp for my computer. I installed it and everything seems to be working but when i open windows media player it freezes and i have to switch the computer off from the power button. it also happens when i open msn messenger 8. I dont know what's wrong ? my computer didnt have a graphics card only an internal 32mb SiS. i uninstalled that then installed this one. Im not too sure if i plugged the power cables in right but i dont think thats the problem. my computer specs are: p4 3.0ghz, 1gb ram, 80gb hDD Can someone please help me as im having major trouble with this.
