My CPU has been running at more than 50%. In windows task manager under Description it had Realtek Audio Device, under Image Name it had RtkNUGI64.exe and it was using 49-50% of the CPU. I checked on a few tech sites and read that it's a virus. After trying many different things over the last 4wks I finally deleted it. Now my CPU is at 2% (finally). I would like sound on my computer but not sure if I want Realtek again. I don't have any sound devices installed under sound now. When I purchased my new PC in October 2011, it came with it already installed but the problem didn't start till Dec. Can you recommend a different one or will I have to get a Realtek again?
