BIOS/UEFI (version 2004) dates from 2014. Please update to the latest available version.
I know that there are a couple of newer updates, but they list changes that don't seem to affect me. When I ran the ASUS auto-updater, it told me that a BIOS update was not necessary. Rather than create new problems, I did not update, but I will if you think that I should.
You have 4 or 5 hard drives. What is the make/model/wattage and age of your Power Supply?
Antec HCP-850 Platinum 850W purchased in January 2014 at the time of the system build.
C: is a Samsung SSD (purchased 01/2014), my boot/Windows drive with most applications
D: is the HDD from my prior build (200GB)
E: is a WD 2TB HDD for mass storage
F: is the old Intel 75GB SSD from my prior build
All four have been in my system and stable since the initial build.
These devices have problems in Device Manager:
AMDA00 Interface ACPI\PNP0A0A\2&DABA3FF&1 This device is not working properly because Windows cannot load the drivers required for this device.
Security Processor Loader Driver ROOT\LEGACY_SPLDR\0000 This device is not present, is not working properly, or does not have all its drivers installed.
NVIDIA High Definition Audio HDAUDIO\FUNC_01&VEN_10DE&DEV_0044&SUBSYS_38423787&REV_1001\5&1F00E892&0&0001 This device is disabled.
ehdrv ROOT\LEGACY_EHDRV\0000 This device is not present, is not working properly, or does not have all its drivers installed.
Please visit the motherboard manufacturer's website and install the appropriate drivers for the first 2
Will try and get back to you.
The 3rd item is disabled. Did you do this deliberately? If so, why? I use the MB's on board audio, the other is diabled to avoid conflicts, I'm not sure what originally tried to install it, I assume it came with the GPU drivers.
The last item appears to be a driver for ESET software. Have you recently uninstall that software? If so, try reinstalling and then uninstalling again.
If not, then I'd have to wonder about malware infecting your system. Please post over in the Am I Infected forums for assistance with that. ESET (my anti-virus) is installed and running without complaints. Could this error be because the diagnostic is being run in safe mode, which seems to disable ESET?
Many, many errors from the Mobizen application.
Uninstall it. I don't know what that application is or where it came from. I'll find and eliminate it -- I can't find any such application installed. It is not something that I ever would have installed deliberately. It's not listed in the Programs list or a file search. The closest entry is "Remote PC Agent" which appears to be the same publisher ("RSUPPORT"), I'll uninstall that if you like. I also just ran a Malwarebytes anti-malware scan which found nothing. Update: Remote PC agent is something which I installed about six months ago but do not regularly use. I have now uninstalled it, though I don't believe it would be connected to my current issue.
See if it works now.
If not, post back and we'll see what else we can find.
