When I start my admittedly old desktop running W10 it starts up fine, but after a two or three minutes it stops dead. No response from keyboard or mouse. I turn the power off, reboot and everything is fine for the rest of the session.
In desperation I replaced the motherboard battery as I know that can cause intermittent errors but to no avail. Bootup is fine, W10 starts OK but then it freezes. But once only. Device manager shows no problem and I have done a Windows update but only after this problem first showed itself about a week ago.
It's not a game changer, but I'm just hoping it isn't the prelude to something worse. Anybody with any ideas what to look at? Ta.
