System won't shut down properly and reboots without warning

mishrak · May 16, 2014

Hi everyone and thanks for reading,

My computer is having issues. It will not shut down properly. After shutting the system down it gives me the shutting down screen and then turns off power to the peripherals (monitor, mouse, keyboard, headphones) but the computer is still obviously running and I need to turn it off at the wall.
At other times, it will reboot without warning and will remain in the half-off state I described above and I need to turn it off at the wall. This has only ever happened from the desktop and never from inside a game. I do not get a blue screen.
Last night during one of these episodes the computer wouldn't even turn on at all. I waited about 5 minutes before it finally decided to boot up.
I sent the system back under warranty last week and it returned with no fault. After getting it back from the repair it did indeed shut down properly. However when I was updating windows (it was reformatted before I sent it off) during the restart install part of the update it rebooted itself and now I have the problem all over again.

My specs:

Intel Core i5 4570
ASRock B58M Pro 4 Motherboard
8gb DDR3 Ram
Nvidia GeForce GTX 760
Windows 7 Service Pack 1 64 bit
Samsung SSD 840 EVO 120gb
ST1000DM 1TB Hard drive
Asus PCE-N15 11n Wireless LAN PCI-E Card

Things I've tried:
Reformating
Reintalling drivers
Removing and reinstalling components
Memtest86 for 24 hours (0 faults)

Thanks for any help you might be able to provide.

Hello... If yor computer is running good there is no need to UpGRADE it...
If you set your Computer Programs for AUTOMATIC updates, you are leaving open any changes "they" want to make to your Computer. Try to Understand and Control what you are Upgrading and chose "Custom upgrade" when at the Windows site.
Take a mental stance on UPGRADES... " If it Ain't broken, Don't try to fix it! "

You can locate a previous Restore Point on your Computer before "they" broke it agian.
Control Panel/System/System Protection/System restore/ check mark "show more restore points" and try and find the date your computer was working well.

I built a rig for my ol'lady. It also doesn't fully shut down. When you shut it off, it turns off everything expect the fans keep running. I haven't been able to figure out what the issue was. It does it even at stock settings. The odd part is she's basically using my old system, expect the CPU/HDD/DVD/case. I never had the problem when I was using the GPU/Mobo/PSU/Ram that is now in her system.

I did have to replace the ram I used in her system because it went bad, and that had no affect on the computer not wanting to shut down.

She hasn't had the issues with restarting, and other then not wanting to shut down her system is rock solid.

What PSU are you using btw?

mishrak · May 16, 2014

Hi thanks for the reply.
Before I sent the PC back for repairs I did a fresh reformat and I was still getting this problem with zero windows updates installed. It's just the thing that set it off most recently.

My PSU is a 600W Silverstone Strider Plus SST-ST60F-PS v1.0

mishrak :

Ah. I was trying to see if there was anything in common... However there isn't much...

Her system,
FX6300
ga-970a-ud3
8gb ddr3 @ 1600
HD 7850
Win7 64
Hybrid Seagate hdd
PSU CX500M

The things in common are the seagate drive, windows 7, and she also has a wireless card.

I don't think the Seagate drive has anything to do with it, because I used the same one you have before, and now have it in my current computer as a data drive. You both have wireless cards (hers i a Rosewill), and tons of people use windows 7.

Sorry man, I'm not sure what the issue is. Was hoping that some part would be the same, but even the mobo are by different brands.

mishrak · May 16, 2014

It's OK thanks for the insight on the hard drive. I've tested the PC without the wireless card installed and I still get the same issue. Glad (probably not the right word here) that I'm not the only one having this issue. I felt like a crazy person when the repair team at the store told me there is nothing wrong with it. Next place for this PC is out the window ><

Control Panel/System/System Protection/System restore/ check mark "show more restore points" and try and find the date your computer was working well. This might determine if it is a software/upgrade issue.

mishrak · May 16, 2014

Thanks Ironsounds that's good to know. The PC still exhibits the problem with a clean install of windows however so I'm just not sure this is my problem. I only mentioned it in case someone is able to relate that to something else going wrong.

I never put much time into trying to figure her issue out since she wasn't bothered by it, and it didn't mess with the system functioning...

Going through the Asus P5B-E Forum I found the fix for this issue and it's so easy a ....well, you know!

Go into the windows control panel and the device manager to the tab for IEEE-1394 Bus Host Controllers and click the tab to expand it then right click for properties and under power managment click "Allow the computer to turn off this device...." and all is back the way it should be!

I'm not sure how this would explain the rebooting, but it's worth looking into.

Ironsounds · May 16, 2014

Hello... there are many BIOs setting for Wake/Suspend PC etc... disable all those settings, save and RE-Boot.
Also there are many Windows setting for Wake/Suspend PC etc in your Performance settings.
There COULD be a BIO's/driver updates for your MB that address many problems like your own for Wake/Suspend at the ASROCK web site http://www.asrock.com/mb/Intel/B85M%20Pro4/?cat=Download

mishrak · May 16, 2014

Chareit: Thanks mate but I dont have a listing in device manager for a device called IEEE-1394 Bus Host Controller.

Ironsounds: I have done as you suggested and disabled the wake setting in windows and BIOS. I also updated to the latest BIOS and drivers. Everything installed fine except the VGA driver and the Intel Rapid Start driver would not install as it said I did not meet the system requirement. I made sure I was installing the Windows 7 64 bit drivers. After this the system would shut down completely for a bit but I'm getting lots of rebooting now, sometimes windows will only load for 30 seconds and now it won't shutdown properly again. I tried booting in Safe Mode with Networking and got the same unstable rebooting.

Ironsounds · May 16, 2014

Hello... I have feeling your hardrive/hardrives? could be at fault now... as you are not getting any BLUE SCREENS?
1) Try checking and re-inserting your Hardrive Power and data cables... any shut down or upgrade would require Data to be completed before shut-off.
2) Try removing your 1TB hardrive power and data connector... and re-boot into Windows and check stability, and then shut down agian... this will determine if the 1TB is faulty.

mishrak · May 17, 2014

No I don't get any blue screens.
I've tried re-inserting the power and data cables and that didn't help.
I also tried disconnecting the 1TB and got a couple of successful shutdowns but that didnt last long. I didnt notice any reboots but they are so random that its hard to say if it helped. Sometimes the pc can go for days without rebooting, at other times it does it within 30 seconds of being started up.
At one stage the system would not boot up for about 2 minutes after a shutdown (clicking the on button did nothing).
Do you think all of these problems are related? The reboots, the shutdown and the fact that it refuses to boot for a couple of minutes after a shutdown?
Thanks heaps for your help so far.

chargeit · May 17, 2014

I'm going to throw this in. I wouldn't be so sure that the rebooting, and not shutting down are related. It could be 2 different issues.

Make sure you aren't overheating. Run something like "Cpuid Hwmonitor". Just shutting off and restarting sounds like a thermal issue to me.

Months back I took apart, and cleaned my laptop. I put it back together using thermal paste for both the CPU, and on board graphics. I found out that the thermal paste left a small gap on the on board graphics, and I should of used a thermal pad (which I since fixed). It did what you mentioned, just randomly restarted, and at times it wouldn't power on. Issue was a heat problem.

If your computer reboots, or just losses power and refuses to come back on it could be because it's waiting too cool down. A computer doesn't want to power on if it is at a thermal level that can damage the hardware.

****I disagree about not updating your computer btw... In this day and age you need to keep your important windows updates "up to date". Other wise you invite security leaks.

Ironsounds · May 17, 2014

Hello... To the above post "chargeit"... As I stated... Try to Understand and Control what you are Upgrading and chose "Custom upgrade" I agree Security Upgrades can be important to some people, but Microsoft Website will install alot of other unimportant files not related to Security, or UN-needed Programs, and Drivers to your Hardware... IF... left to Automatic upgrade settings.
A Standard install of Windows 7 works without problems... and will be good enough to test/run any hardware/programs you have.
I would like to also know your PERSONAL experience with your computer and security leaks?
I stand by this statement through my life with everything " If it Ain't Broken don't try to FIX IT!!!

The only time I see computer problems with people around me is when they click the Icon on the screen that SAYS "Upgrade NOW" or "Install NOW" and you just invited security risk and un-tested software into your computer.

chargeit · May 17, 2014

Ironsounds :

Microsoft is plugging security holes all the time. I personally set it to install all important updates. Optional ones are a different story, and you should figure out what it is being updated before installing them... Things like "Bing search bar" are worthless and should be denied. Up dates for printers, and other devices that like you said "are working" shouldn't be updated.

Also don't forget that you might be more computer savvy then the next user over and be able to get away with not installing all important updates.

I've never had issues with updates myself (well, not since XP), but yea, I only allow important ones, and then research the rest.

mishrak · May 17, 2014

To be precise, when it "reboots" itself, it puts the computer in the incomplete shutdown state that I get when I try to shut it down manually and I have to turn it off at the wall. So it doesnt actually just reboot me to windows at all. Might have been the wrong word to describe the problem.
I just ran CPUID HWMonitor and all temps look ok to me, the highest value is on the motherboard at 44 degrees Celsius and everything else is hovering around the high 20's and low 30's.
One thing I do notice when it does the incomplete shutdown is the power supply fans keep running for a while (even with the wall power off) and I've begun to notice an occasional buzzing sound coming from it when the computer is running. Not sure if that is normal.

chargeit · May 18, 2014

You said it didn't happen when you got it back from the computer shop... Maybe you can just set your system back to factory, if you have a recovery CD...

You could do that by pressing F8 as the system is posting.

The point of this is to test it and see if it still reboots. You said updates made it start happening? You may want to test that out, and see if at true stock the system reboots. I'd try it out for a few days, with out internet connection. (for security reasons)

If that helps it, then update only important updates. Then be very selective with the optional ones. The optional ones aren't security related, and usually update drivers, or features that are less vital.

If your computer still reboots you removed updates as a possible cause.

There is no telling, since updates could cause something in your system to have wacky driver issues.
