I didn't use my work laptop for close to 2 months and since then I've been having issues. First, I bought new speakers branded instudio by the source, that's when I've been getting sound problems with my laptop. At first, issue was only on firefox, so I uninstalled firefox and reinstalled it and seemed to fix the problem. But now, since last saturday, whenever I play on chess.com the sounds starts distorting after a minute or so and it effects my whole computer. So sound either disapears or distorts on whatever browser, site, harddrive etc. I reinstalled the sound driver but still the same issue. Also my computer has started freezing on occasion, it has never done that before either. My laptop is a dell latitude E5500 with windows 7 pro. Please help me thanks.
