Hey guys, well recently, the last week, I keep getting Audio glitches ...But it only happens to the AUDIO , The video seems to be running normally with no glitches. It happens everytime i'm watching a DVD, It was never ever a problem till recently, I've tried all sorts of things, I've tried un installing codecs, re-installing codecs, Audio drivers. My Laptop is An ASUS M51Sn intel core2duo 2.5 ghz , 3GB RAM, 250GB hard drive, NVIDIA GFORCES 9500GS M 512MB video card,,
I'm pretty sure it can handle watching DVD's, cause i have been with no hassles the last year or so.. I can't restore. cause i've got system restore, off, Along with other services to speed up my system. If anyone can help me it'll be much appreciated guys THANK you !!!
