I had computer problems and someone from here helped me fix it but now I can't play call of duty at all I can log in and get into a game but then a minute into it it crashes and reboots my system. Also my headset doesn't work. It is Logitech clearchat wireless pc headset. I have had it for almost a year and it worked fine . All the lights light up but it doesn't show up in my sound and audio. Like it isn't there. I tried different usb ports but it says it is working. Can any one help me?
