Alright, so, yesterday I noticed that it seemed to take a little longer than usual to start up my laptop (HP Pavilion 17-7042nr with Windows 8.1 64-bit; I've only had it a short amount of time and it was purchased refurbished). I didn't think too much of it, however, since I was starting it at the same time as my seven-year-old Vista machine so by comparison it was still way faster (20+ seconds vs. the old one's 2 minutes). After that, didn't think anything of it...
Today, however, I started it up on its own and it took far too long compared to how it used to behave. I've noticed this a few times in the past, but always figured Windows was adjusting itself after I'd installed stuff etc. But since there was no need for it to do that this time, I got suspicious and started looking in the event viewer. To my shock, it claimed that the last shutdown was improper and that's why it took forever; it was actually rebooting.
Trouble is, as far as I knew, no it most certainly did not shut down improperly. I turned it off using the power button, which is set from the power plan to perform a shut down. It did the normal thing: processed the shut down, turned off the screen, and shortly after turned off all system lights except of course the one to indicate that it was plugged in. All seemed well, and was not slower than usual or anything of that sort. So I have no clue why or how it's shutting down improperly.
But not only that, I tracked it back and several times, as far back as the 19th of February (as well as a couple of times while it was in HP's custody for unrelated maintenance; they apparently did not notice it, either, as it was given a clean bill of health before return) this has been occurring. I've transferred a ton of files, settings, programs, etc. since then so I really didn't want to do a Restore. I did, however, consider it... only to discover that my previous Restore Points before the system was returned by HP have been destroyed. So no chance of going back before the 19th, even if I wanted to (I don't, frankly).
I have no clue what's going on, but here's the events from the first ever time it happened:
the logoff/power down is listed as:
Information 2/19/2015 5:09:11 AM Kernel-Power 109 (103)
-- "The kernel power manager has initiated a shutdown transition."
Information 2/19/2015 5:09:37 AM Winlogon 7002 (1102)
-- "User Logoff Notification for Customer Experience Improvement Program"
after that the next relevant things which involve the boot up:
Information 2/19/2015 4:42:36 PM Kernel-Boot 20 None
-- "The last shutdown's sucess status was true. The last boot's success status was true."
Error 2/19/2015 4:42:36 PM Kernel-Boot 29 None
-- "Windows failed fast startup with error status 0xC00000D4"
Critical 2/19/2015 4:42:45 PM Kernel-Power 41 (63)
--"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
Error 2/19/2015 4:43:14 PM EventLog 6008 None
-- "The previous system shutdown at 4:59:42 AM on 2/19/2015 was unexpected."
Information 2/19/2015 4:43:21 PM Service Control Manager 7026 None
--"The following boot-start or system-start driver(s) did not load: dam"
Those were from the 19 of February, the first time it seems to have happened. The most recent (today) incident is very similar, but not entirely identical.
The shutdown was:
Information 3/17/2015 5:12:16 AM Kernel-Power 109 (103)
-- "The kernel power manager has initiated a shutdown transition."
Upon boot the seemingly relevant bits are:
Information 3/17/2015 4:47:55 PM Kernel-Boot 20 None
--"THe last shutdown's success status was true. The last boot's success status was true."
Error 3/17/2015 4:47:55 PM Kernel-Boot 29 None
--"Windows failed fast startup with error status 0xC00000D4."
Information 3/17/2015 4:47:55 PM Kernel-General 12 None
--"The operating system started at system time 2015-03-17T21:47:45.491075600Z." (( What even is up with that time??? ))
Critical 3/17/2015 4:48:01 PM Kernel-Power 41 (63)
--"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
Error 3/17/2015 4:48:24 PM EventLog 6008 None
--"THe previous system shutdown at 5:12:03 AM on 3/17/2015 was unexpected."
I tried googling, to no avail, other than a suggestion that it might be caused by some sort of system file issue. So I ran "sfc /scannow" in an admin-level command prompt and when it was finished it said: "Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not supported in offline servicing scenarios."
I tracked down the log file and it's rather huge but toward the end I found that "Amd64\CNBJ2530.DPB" was corrupted. Naturally, I investigated... But according to the thread I found it's some kind of printer-related thing, and I've never even connected a printer to this system, much less a Canon brand one as the info I found suggested. In fact, the thread I linked claims that it shouldn't cause any huge issues, so... Probably not the cause of my shutdown issues, which are more pressing. Thus, I can't find anything to indicate what's causing this problem.
The only thing I can think of that I had done around the 19th was I was trying to get rid of Beats Audio crap on my laptop. (Don't even get me started on that hot mess!) So I'd been swapping between the Windows default audio drivers and versions of the Realtek High Definition Audio from both HP and Realtek. But I never had a corrupt install and I don't recall installing one over the other without uninstalling first, so I don't know if that's an issue. Somehow, I doubt it, especially since this issue isn't consistent. Then again, I don't consistently use the audio on my computer so who knows.
After all lights are off and the system is shut down, unless I've been using it on battery and it needs a charge, I unplug it to conserve energy. I only ever do this if the battery has a full charge, so I don't think that should be an issue even though hybrid shutdown/fast boot is some kind of hibernation-shutdown combination. I'd prefer to keep fast start/hybrid boot enabled because, well, it's convenient... and I'm extremely hesitant to tamper with the UEFI settings etc. But, of course, if that's the only fix then I'd prefer it to possible hard drive damage caused by the supposed/apparent improper shut down.
Also of note: nothing is overclocked or running outside specifications, as far as I know. My system stats are:
Windows 8.1 64-bit
AMD A10-5745M APU
AMD Radeon HD 8610G
UEFI BIOS Mode
Secure Boot Enabled
Any help would be greatly appreciated!
