Over the last two weeks, I've had a number of Windows 10 computers go into a looping restart. Upon system power up, a Windows logo appears for a short bit with a dotted whirligig... the screen clears and is followed by a second dotted whirligig... after another short bit, the screen clears and the system drive activity light flashes for some 20 - 30 seconds before the system restarts and the sequence begins again. This looping restart continues until power is removed from the system.
I've tried booting from a Windows 10 installation CD and running Repair. Startup Repair does nothing. System Restore does not remedy the looping restart. Chkdsk with /r does nothing. The one time I was able to get the option to start in Safe Mode, the looping restart prevailed. On earlier systems, I simply restored from backups. On this particular system, it has no backup to recover to. Yes... I've created a full image backup of the drive so I can recover data. But I'd like to think that I made every possible recovery attempt before I perform a clean Windows install, return the client's data and inform them that they'll need to reinstall programs, printers, email, settings, etc. that are now lost for good.
Any ideas? I have a stinking suspicion that this won't be the last of these symptom computers that I see.
Thanks for reading and giving thought to this!!
