Hi guys, I had Win10 installed on another machine I had laying around the office, and had minimal issues with it. I installed it on my SP3 a few hours ago, and now the poor SP3 is a heaping pile of uselessnes. The installation went ok, and I was taken to the setup screen where you pick your WiFi and sign in to your account. It then took me to the Start screen, and then at that point the screen would flash black every 15 or 20 seconds, and the keyboard and mouse were mostly unusable except for 2 or 3 second periods after a black flash. It would flash for 5 or 8 times or so and then just immediately reboot. I let it do that about 3 or 4 times before I figured it was hosed. I really felt like if I could get to Windows Update and download new updates, it would fix the problem, but that is absolutely not doable in the regular Desktop/Start environment. I made it into Safe Mode, and the machine ran beautifully then, but Windows Update isn't available in Safe Mode. As well, there were no restore points for System Restore to use. What do you guys think, am I going to just have to wipe the whole thing and reinstall fresh, losing all my data? All my important stuff is backed up, I haven't lost anything important.
