I've had this problem for months now and I'm at a loss about what to do next. I've ran the Windows Diagnostic Tool- multiple times. No change. I've refreshed my PC. No change. I've just recently reset my laptop back to factory settings and still nothing has changed. Honestly, I don't know what else to do. Most of the other threads and articles I've read state that resetting Windows is a last resort. But if that doesn't work, what else will? Can someone help? This is getting frustrating now. I have to wait 20 minutes at least to get into my PC every time I shut it down. All help appreciated!
