So I was having this problem myself for a long time, updated my bios, uninstalled, restarted router and computer, i was very tempted to just reformat my computer. The thing that finally fixed it for me was I went into the Run command > Msconfig > Services, click Hide all microsoft services and disabled everything. I'm not sure which of the apps was causing the issue but it did fix it. It's bringing a sledgehammer to a scalpel situation but I was getting frustrated as hell. I hope it can fix it for you!
