A new PC which was recently deployed a couple of months ago with Windows 8 was upgraded to 8.1 lover the weekend. The PC was working perfectly until this morning (Thursday morning, here in OZ) when the client turned the PC on. The mothboard splash screen appeared, as did the choices at the very bottom to access other features via DEL, F12, etc. After 2-3 seconds, the options at the bottom disappeared, but the motherboard splash screen remained.
I rebooted and went into BIOS to confirm that the boot settings hadn't changed - they're all good (boot HDD is set to boot 1, BDR to boot 2 and DVD to boot 3 (no other options installed/ present).
Any thoughts on what may have caused this or, more importantly, what can be done?
I don't have any immediate concerns about power surges or hardware failure as everything looks good on that front (as much as you can tell with your eyes a simple deducing).
Did a Windows update come through in the last 24hrs which could have caused an issue? The PC was on overnight, so I'm not ruling this out until I know otherwise.
