Hello, I've recently built my desktop with asus h270 prime plus i5-7600 with intergrated Hd 630 graphics, 8gb ddr4 ram, psu 800 wats and sata hdd 2 tb but I experience choppy sound in videos even local ones, lagging in games that should be fine to run like black ops 1 (which is unplayable for the moment) and also stuttering, though in skyrim there are no problems neither in Call of duty world at war, just some sound issues which makes it sound choppy and laggy. What can I do to fix that? I have the latest drivers installed and nothing else seems to be the problem. Does anyone have a solution? I would really appreciate any answer. Thanks in advance
