Hmm, well it's good and bad I'm afraid. Gotnit all set up beautifully in the new case. Powered on and posted, got into bios to set the date and time, check through a few settings. Turned Windows 10 WHQL mode on, set boot order for USB Win10 stick. Boot to USB fine, start the install, first reboot happens, removed stick once it restarts and it posted okay, went to MSI logo, spinning windows loading icon thing... Preparing devices got to 100% and it rebooted and then it never posted again... Left it for five or ten, no change, restarted, no change, BOOT LED lit up after its powered on. Tried shorting the CMOS pins, no change. Unplugged and reset CMOS again, going to leave unplugged until tomorrow afternoon after work to see if anything changes.. Any ideas?
