Windows 8.1 HTPC - Unexpected Power On
Feb 8, 2014
I'm troubleshooting a Windows 8.1 HTPC (ASrock Vision 3D 252B) that sometimes starts up on his own.
Unexpected power on seem to be periodical, but checking scheduler, registry and BIOS, there's no scheduled power on.
It's connected to a SmartTV via HDMI, but unexpected power on happen also when SmartTV is off, so I think this is not a cause.
This computer is often powered on via WoL but, if there's no stange packets coming, i think this is not a cause, too.
I've just been disabling RTC Wake Up in BIOS, I have no idea what this feature is.

this laptop is freezing - requiring a hard reboot - every week or two and I can't seem to determine from the logs where to look.

I use a Logitech k400 Wireless keyboard with a built in trackpad. It's great in theory, but the implementation has a few flaws:
The keys are small, and the trackpad is worthless, especially with Windows 8.
I've been trying to find an alternative, but the only one I found is using apple inputsw and something called a "Magic wand" which connects the two:
Here's what I'm thinking of doing:
Buy a Logitech Wireless Rechargeable Touchpad T650
Buy a Logitech Wireless Illuminated Keyboard K800
Buy a board slightly bigger than the footprint of both of these devices, and a bunch of velcro.
You can guess the rest.

I got my desktop to make it %300 bigger and it's a good size. Right now I have my metro UI as "Make everything bigger option" but it's still hard to read it on my 42 inch from 15 feet away. Anyway I can make the metro UI (windows 8 UI w/e) scale like the desktop?

Windows 8 has a nice clean interface that is very touch-friendly, which makes it incredibly easy to use with a wii remote. It also is not locked down at all - it can do virtually ANYTHING your current pc can do (though you might prefer to only use the apps that are ported over to metro)
All you need is the driver, bluetooth, and a couple ir emitters. And maybe a wireless keyboard.

So I've taken the plunge and installed Windows 8 on my HTPC that is connected to my main TV. The start screen really works when sitting at a distance from the PC with the big icons for plex and netflix etc, the weather and other metro apps also fill out the screen with nice info and images, the browser is better suited.. it's perfect... ....almost.
VNC is a bit of a nightmare, I had VNC server installed so i could use HippoRemote and connect to the box via a VNC client.
My MAIN problem is that the mouse does not move with my gestures or movement of remote mouse.. the pointer doesn't move.. The mouse is there, but since i can't see it I am forced to guess where it's at.. it's not so bad on the start screen because tiles are highlighted as you move over them, but if I am in an app or on the desktop it's almost impossible to use because i have no visual mouse pointer.
I downloaded an iOS app called windows 8 gesture pro or something but it's rubbish and not being updated since it hasnt been updated on iphone 5 and it crashes when i try to access the virtual keyboard.

For the past couple of months, I have been noticing unexpected freezes on Windows 8. Since I have access to MSDN, I decided to do a fresh install of Windows 8.1 to see if it solves my problem.
Now, when it freezes, it actually shows me some useful information. BSOD is labled as BAD_POOL_HEADER and I have grabbed the 2 dump files and other info in the zip file attached to this post.
Memtest and Chkdsk show no problems after running both. Memtest did about 6 passes last night without any errors so I know for sure it's not a problem with my RAM. Chkdsk showed no errors after running it in my 8.1 bootable USB so my SSD is fine. I also have the latest Kingston SSD firmware. NVIDIA Graphics card drivers are also updated to support Windows 8.1. Still not sure what's causing it.
BlueScreenView shows the following confilcts:

I just recently bought a new HTPC server and installed Windows 8.1 on it. Everything seems to work great except my USB mouse and keyboard. The range of these wireless devices dropped to just about one meter. They work further away if I lift them high in the air but from waist level they only work from very close ranges. Before they used to work perfectly from distances up to 5 meters.
What's odd is that the USB recievers are in the exact same spots as they were in my old computer. I have an extender cable and a hub so there are no obstacles between the recievers and the devices. I'm not sure whether this is because of Windows 8 or because of the new hardware. My previous computer was a laptop running Win7 but the new one is a desktop. The devices seemed to work bad even in BIOS so I suspect it's the hardware.
I have installed latest drivers, replaced batteries and tried different positions for the recievers but nothing seems to fix this issue. I have not added any new wireless devices in the household.

On my HTPC, I used to be able to boot Win 8 Pro in about 12-15 seconds off of my M4 SSD. Recently it's taking almost a minute. what could have caused the slowdown and where I should look?

Windows 8 keeps downgrading my screen setting to 30hertz on my HTPC. It happens every couple of days... It's very annoying and each time i have to go in my screen settings and put it back to 60hz... Is there a way to force 60hz forever?

I have a Dell Inspiron 7537 running Windows 8 64bit. 8GB RAM, i7 processor. A little while ago it suddenly shut off. I went and checked the event viewer and got the info below. I think Toaster.exe is Dell's Backup and Recovery software, is that correct?

On my home network, I have my desktop, my HTPC (wired) and my wife's laptop (Wifi). The desktop and HTPC are bth running Win 8 pro. The laptop is running Win 7. All are 64 it.
Invariably I try to log onto my HTPC from my desktop and it says that I am unable to access the files. I then open up network and sharing center to check on the network password only to find that is has changed itself somehow. Even after I reset the password on both the HTPC and the desktop. I still cannot access my shared files on the HTPC from the desktop. The only way to share files is to get them from the HTPC which for some reason lets me access my desktop files.
The laptop is not really an issue. ONce I enter the new password I can access files on the desktop and print no problem. I guess the 2 issues are...
1) the random changing of the network password
2) the inability to access networked files FROM the desktop. The reverse seems to work flawlessly.....

Main Symptom : The new PC stops responding after several hours (sometimes a few) of intensive work and then it shuts down.Sometimes it produces a blue screen with the "critical process dies" message and sometimes doesn't.The problem was appearing also after fresh install of 2 versions of windows 7.Now in official Windows 8 it appears also.All these 3 windows versions were working fine on other desktops.
Event viewer : One critical error appears every time : Event ID 41 , task 63 , kernel-power.
Connected Peripherals :
1)Keyboard
2)Stylus pen
3)Printer
4)Wireless usb adapter
5)Stereo speakers
6)usb hub
7) four external hard disc drives
What I personally tried so far and what the technician did :
1. Tried 3 versions of Windows to see if the problem had to do with them.The problem appeared in all versions.
2. Updated all drivers and MB and VGA drivers of course.No result.
3. Ran memtest and hard disc check.No problems.
4. Disabled one of the two audio drivers ( disabled nvidia audio and left enabled the realtek audio).No result.
5. Disabled sleep.No result
6. I personally checked for 3 hours how the PC responds with only mouse and keyboard connected and without heavy use. The PC didn't crash.The technician also did the same with his mouse and his keyboard for 10 hours but without heavy use also.The PC didn't crash. The technician returned my PC and said that he couldn't find any problem in his lab and that the problem must probably have to do with the peripherals.
So when the problem really appears : The problem appears when all the peripherals are connected and after a little bit of intensive use. ( Photoshop many hours - Transfers of thousand of images from one external hard dick to the other - Printer and internet use ).
The same peripherals were used on the old PC with winxp, in the same electricity plug, and there was no problem at all.
I have spent a lot of time to understand if the problem is software or hardware related.My guess goes to a possibly problematic PSU.The PSU is Corsair 650W and new of course but i think it can't handle many peripherals and intensive use.If the problem was driver related then i guess that the crash would appear not only after heavy use but also after normal use.Another guess is that there is a problem with usb controller and that's why the peripherals that are connected via usb are causing problems,
I attach the SF diagnostic folder.

My friend happened to look in Devices and Printers, and in the Multimedia Devices section he had about 10 devices showing up that he never heard of. Six of them were computers with names that he had never heard of, the others were devices that we could not tell what they were.
I expect that these entries mean that at some time they were on the same network that he was on. Would that be correct?
If so, then it is a matter for concern because he never goes on public networks. He only goes on his network at home, and a network in a small office that he rents and shares with one other person. They have their own router with security set up on it, and that router is connected to an Ethernet jack that most likely goes to a switch on a network that also provides internet service to some other offices in the same building.
This computer is only about 2 months old, so these entries can't be too old.
When I looked at his computer, he was on his home network and all those other devices showed as Offline. I right clicked on them all and removed them. Would it be a good guess that perhaps the security of the network at his office was compromised, and those devices were connected to that network at some point?
I told him to monitor and see when they reappear, but he won't be back in that office for 2 weeks.

I recently had a crash on my system while updating my ATI Radeon HD 5450 graphics card.
This occurred yesterday while updating to Catalyst v13.1, released on Jan 17 2013. Once I start the install, at around mid installation the BSOD appears and restarts my computer. I have since then done a clean install of Windows 8 Pro and it keeps appearing every time I try to update my graphics card. I've had this card for about a year now and with no problems until now.
The crash dump file appears in c:/windows/minidump
PC SPECS:
Gateway DX
Windows 8 Pro 64bit
AMD Athlon X2 Dual Core 2.7Ghz
6GB DDR2
ATI Radeon HD 5450 1GB

As the title says, I'm getting a box saying "An unexpected error has occurred" whenever I try and access the properties window for my ethernet adapter. An unexpected power outage earlier in the day rendered my Windows 8 installation half messed up, leaving most of my drivers corrupt, so I had to attempt a refresh today, which solved most of my problems.
Unfortunately others like this have been cropping up since the refresh. I've looked for other possible solutions to this problem, and none have worked so far. Re-registering DLL files solved nothing, a system file check didn't do anything, and making sure I was in the correct user groups didn't solve anything either.

I just noticed that when I go to the Power Options that the options are missing. It says the Power Plan is missing or unavailable or something such. One answer said to do a refresh or reset of Windows 8. Isn't that a bit drastic? Is there no way to do it by tweaks. I did that refresh once and lost more than I thought I was supposed to.

One day I go to shutdown/hibernate/sleep button and a pop up says "no power options available". I can still preform these options but I have to go through signing out first then picking. How do I change this? Oh, and no, I didn't add or upgrade, etc. anything lately.

I realized something interesting what happen using Windows 8 and 8.1, compare to Windows 7: a quite huge difference in power consumption!
For some special reason I was need ti install Windows 7 on my computer at home. I done that on an new HDD with 320GB, running solo for the installation by removing the power cables form the other HDD's, a total of 8 SATA3 HDD's. That was done 2 days ago and I firstly I installed only those Apps I need to use on Windows 7, no any gimmiks, whistles or bells! On Windows 8 I use Gadgets and the CPU Gadget show at middle 20%-25% while doing normal work.
I also have 3 different power circuit's at my home office, to each an Ampere Meter connected. On the circuit with my computer, which is connected to an 1.2KW UPS is also the Modem/Router 4 Port, LAN Switch 8 Port and and Debian Linux Server running. 2. Power Circuit has an Survailance Server and an Mail Server running and 3. circuit is for the normal other electric use like lights, power plugs etc.
Now on my computer's circuit the Amp Meter is 0-10A and with Windows 8 and 8.1 and the other devices, as pointed above, the consumption is about 2.6A-2.7A, depend on the work done on the computer. There is only 1 printer connected via the same power circuit, an Brother QL570 Thermal Label printer which is 99.8% of the time off line!
Now the interesting: running Windows 7 on the exact same computer with all HDD's running, as Windows 8, the power consumption is between 2.2A and max 2.4A! So, I installed more apps, mainly now the same a s running in 8/8.1 and also the gadgets. The CPU usage is mainly between 2-6% and may goes up to 15% by heavier work but reach 20%!
Both, the CPU usage and the power consumption is a quite huge difference using the exact same hardware, only difference is the OS Windows 8/8.1 vs Windows 7! In this, Windows 7 wins clearly!

I've had Windows 8 sitting around since February, and got around to installing it yesterday. So far all is well, except for when I shut my computer off the power LED will keep flashing. At first I thought my computer was just in sleep mode, but after hitting a couple keys that was not the case. Is there a setting some where that would cause this. I know it's a minor issue but damn that LED is bright.
My systems specs
Intel Core 2 Quad Q9300
EVGA 123-YW-E175-A1 LGA 775 NVIDIA nForce 750i
Seagate Barracuda 7200.10 ST3750640AS 750GB
CORSAIR XMS2 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800
Yeah this machine is over five years old, working on getting a new one together soon.

My computer won't power off completely, SOMETIMES, i'm going nuts here.
Here are my system specs:
ASUS Forumla IV latest BIOS
ASUS GTX 690
2x4 2333 GB RAM
ANTEC 1200W PSU
1 SSD & 4 HDD
Creative ZXR SB
using latest drivers for all the above
sometimes the PC power off completely when i shutdown, sometimes not, the screen would go black but the power won't get turned off, the fans are still spinning and no BSOD...I have to either hard reset or hold the power button to turn it off.
I tried resetting CMOS, turning on and off the Fast boot feature in power options
With or without overclocking
Is there anyway to diagnose or investigate what is causing the PC not to power off completely?

I recently upgraded to Windows 8 (64-bit) and noticed I don't have power options available. I own an HP Pavilion DV7, usually when I leave the laptop to do something over night, I go into "Choose what closing the lid does" and I get the error saying my power plan info is not available. Whenever I try to create a powerplan it tells me the same thing, but when I hit next, it tells me it can't find the file specified. I have no power options at the moment. I tried resetting to defaults using cmd, rebooted, and the only power option I had (Razer Gamebooster) was gone, and had nothing after.

I installed clean Windows 8. I checked the event viewer to see if everything is OK. But it has 4 critical error and they were all Kernel Power Error. I noticed these Kernel Power Errors are caused by when I restart my PC. Example is when I installed Photoshop, I restarted and I checked the Event Viewer Log. There was an event Kernel error created.
but here is where it gets complicated. When I boot to desktop after restarting my PC, it doesn't say my computer suffered from a serious error. I have to check it manually by going to the Event Viewer Logs. If I don't check the Event Viewer Log, I won't know.
There has also been times where my PC won't boot to Windows 8. I goes past BIOS and Windows boot screen, but it hangs there. It simply crashes.
I don't overclock my PC. My PC temps are always low old IDLE and always within the max temp under full load.I have installed and updated ALL drivers and BIOS. I thought this might be driver issue but I realized this happened when I installed it clean and booted up for the first time.
This does not happen in Windows 7. Only in Windows 8.
I ran Prime95 for 12 hours -- no error
I ran Intel Burn Test for 9 hours -- no error
I ran Memtest for 12 hours -- no error

Lately just after I updated my Windows 8.1 all of the sudden my PC started shutting down for no reason and I had to restart it. It often occurs during the morning hours, but it also occurs during the evening hours, too. It's a Kernel Power error with Event ID 41, Version 3, Level 1, Task 63.
Here's the zip file and text document attachments I made which contains more information about what's going on with my PC.
