Had really odd problems and given what happened to me and others the first step is to be absolutely sure your files and more are on backups. HP will reset the machine when they work this issues. But given my experience I'd go for refund.

I dunno if "Stutter" is the correct term but it's what describes what happens. Every minute or so the blue work wheel will pop up and it try to type anything, nothing will happen for a few seconds. It happens with the same rythem every time and my games or beefy programs will minimize when this happens. They don't crash and the games will even pause for me, I can open them back up and there is no problem, but evey few minutes they will minimize again. Youtube, Netflix, and Hulu are unaffected. I ran with Norton and the PC Diagnostics inlcuding stratup diagonostics and it's all coming back as normal. I have an HP Omen Notebook with Windows 10. The problem t servere when I use microsoft word and my Outlook wont open, it'll only start up and then crash. I belive the problems may be related.
Any help will be appreciated.
