Thanks to Microsoft for provide such a helpful place.
Have someone ever met a explorer.exe - System Warning dialog with "Unknown Hard Error" message?
I upload it to link postimg.org/image/grsj6f7r1
It occurs while I boot into Windows 8 and go to Metro
System will stay at this condition unless I close the dialog. But System runs well after then.
It only happened sometimes when I boot into Windows 8, but it blocks my work because I need to test system stability by automatic reboot continually.
I have several units and all of them have chance to see this problem, all of them have different hardware configuration, so I think it's not related to hardware components (HDD, RAM)
I've also done check disk by chkdsk /r /f
Hoping can get solution or some inspiration to get rid of it.
Thanks in advance.
