This is a problem that has plagued me for months to the point where I just want to buy another tablet it is so irritating. I turn on my SP3 (running Windows 10) and swipe up the start screen. The first thing I see is an error message telling me that Office 365 cannot connect, which tells me that there is no internet. I try to click on a program icon on the taskbar (e.g. Word or IE) and nothing happens regardless of how many times I click. If at this point I go away and cook dinner and come back, I find that the program I clicked on does open eventually (after about 10-20 min) and in fact several copies open if I clicked on the icon several times. If instead I click on shut down, the blue shut down screen appears and the circular waiting dots continue round and round forever. Instead of waiting, I usually do a hard shut down by holding down the on/off button. After waiting a few seconds, I press the on/off button once as normal to start my SP3. Nothing happens, and regardless of how many times I press the on/off button, it will not start for about 5 min. No light on the keyboard, no flicker on the screen, just nothing for 5 min. Has anyone had this kind of experience with SP3? It seems like something takes over the computer when it starts and just locks it up, even when I try to restart it. I run Kaspersky Total Security and now regularly use PC Mechanic to remove any redundant links in the registry file, performance issues and stealth startup programs that I don't need. The problems started when running Windows 7 (before upgrading to Windows 10) and I installed a driver for my printer (from the manufacturer's website). I have since of course removed the printer install but the problem remains. This problem happens every 3-4 times that I start the computer, so it is a real pain. Any ideas on this?
