Upgraded the BIOS, and that solved it. Hope this helps others!
Hi all, I have a very strange problem. (Preface: this did not happen with previous Win 7 install) Every *other* (see below) time I cold start Win 10 (after upgrading from 7,) my rig stalls right after the BIOS boot, right before Win 10 starts. No drive activity at all. Now here's the weird: Win 10 eventually starts. I set a time-lapse video camera on it, and it's taking 11-12 minutes, then it boots fine. No reboot, the straight boot just starts like regular. Now if I don't want to wait, I can hard shut down via holding the power button and it will boot fine, no delay from that action. I have a slight suspicion that it may be the BIOS holding things up? I have a 2014 Asus Z97-P with BIOS version 2202. That is about 4 versions old. I wanted to see if there were any solutions to this before I upgraded the BIOS (as that seems to be a pain because Asus support kind of sucks in this area.) Wake from sleep is normal. Any thoughts? Has this been tackled yet?
