So, I received my SP4 i5 on Monday and after loading Office and a few apps it was taking over 2 minutes to boot up. I called up Microsoft and went through (painful and lengthy) troubleshooting, which ended with them telling me to clean the device and reset. The device got 8% through the Win10 reinstall and froze so they sent me a new SP4 (after hours of more troubleshooting and convincing). Now I have the new device, reloaded Office and some apps and the same exact thing is happening - a boot time of about 2.5 minutes. When I turn on the device, the "Surface" splash screen shows for over 2 minutes with no action until eventually the rotating icon appears and it boots up. Anybody else having this issue? It's two units with the same issue for me and I haven't loaded any unusual software nor spend much time on the web (not a virus). I have there other Win10 devices and they all boot in less than 10 seconds (SP1, HP Envy desktop, HP Stream Atom tablet). Other observations: the unit seems sluggish (right now it's now keeping up with my typing), once the digitizer/touch screen stopped working and I was receiving an error that the Intel Display Driver stopped working and recovered while working in o365 Word online.
