So I just bought a Samsung 850 EVO 250gb SSD and wanted to install Windows 10 (64 bit) fresh on it. I downloaded the media creation tool for windows 10 and installed it onto a USB. Everything was fine and I installed windows 10 no problem onto my SSD but from the get go after installing Windows 10, I started to notice moments where my keyboard would freeze (can't type for a few seconds, and if I was typing, it would hold a key down). While this keyboard freeze would happen, my mouse cursor would also freeze in place and then teleport across the screen once the freeze stops. I never once had this issue on Windows 7, so at first I thought it was something to do with Windows 10 but that was ruled out after I down graded back to Windows 7 by doing another fresh install. Each time I installed all of my drivers and there were no problems found in device manager troubleshooting. The keyboard is a Razer Blackwidow Chroma and the mouse is a Logitech G500. The weird thing is that the problem also happens with my cheap $20 Microsoft keyboard and mouse as well. I have found two things that remove this lag: 1. Having no keyboard plugged in and just using a mouse, which further shows that the keyboard is freezing the mouse. 2. For some reason and I have no idea why, but being in a skype call with someone completely gets rid of the freezing on the keyboard and mouse. So yeah here I am having installed Windows 10 again (I actually like it a lot more than 7) and still having the problem, I am pretty much all out of ideas and been trying to fix it myself searching online every day for 4 days now. If anyone thinks they might know some ideas I could try out I would greatly appreciate it!
