My computer hasn't been acting right ever since I installed my CD burner. There is no sound, I tried to reinstall the sound driver but still no luck. My resolution is stuck on 600x400 and when I try to change it in the control panels, nothing happens after I restart it. I also tried reinstalling the driver but no luck either. I dont know if it has anything to do with the burner or not. any ideas out there. i'd appreciate it you can also email me. thanks. Text
