Ok so I got myself a new computer it's a Intel core 2 duo 2.0gz, 2gb ram, 550w power supply, I'm running the onboard video and onboard sound. So my problem is when I run a high end program or say try and install something sometimes my sound will bug out and be like breaking up so I cant understand anything and it will fix when the program finishes. But sometimes if its a game I am playing when I load up the game it happens but when the game begins to stable the audio becomes clear but with occassionaly breaking and static type. I have also tried it with a pci sound card also with fully updated drivers and it did the same thing so I know it is not my onbaord sound that is the issue. The only thing I could think of is that it is my onboard video but I dont know does anyone know what may be causing the issue?
