Audio Track Problems

A lot of my audio tracks start out sounding fine but either eventually play only silence or sometimes play a loud glitchy noisy signal. To fix this issue I end up having to clear out the project pool of the offending audio files and then re importing the files which works for a while but then ultimately the problems continue to occur. The files are all playing from my main hard drive so there shouldn’t be any streaming problems. Is there any way to fix this?
