Windows 10: What could cause my PC to reboot spontaneously?

Having run smoothly for years, my PC spontaneously rebooted on 26 June and has done so about 30 times since then, sometimes running a week without problem, sometimes rebooting twice in one day. The screen suddenly goes black and it reboots. There is no blue screen or error message displayed. The event viewer does not report any significant error other than event 41: The system has rebooted without cleanly shutting down first.

I always run the latest version of Windows with all updates.

What could be causing the PC to reboot spontaneously?

Omnia 7 spontaneously rebooting.

I have a Samsung Omnia 7 which is now spontaneously rebooting. When it reboots, it typically will reboot several times before it will run for more than just a couple of minutes. I had to return it to Samsung to be repaired because I couldn't update the
firmware to allow for the last update, and ever since it returned the phone spontaneously reboots. I can be using Internet Explorer for as little as 3 minutes before it reboots. Typically if I play music and use IE then it will reboot after 15 - 20 minutes.
The same with playing games. When it reboots, it appears like the boot process doesn't go quite as normal (often the windows phone logo screen won't appear and it goes from displaying "Samsung Omnia 7" directly to the SIM code screen).

So far I think its a hardware issue, but its so damn hard to find any answers with any depth regarding issues with WP7. Has anyone else experienced this spontaneous rebooting? Any ideas what could be causing it? I am seriously thinking of returning the
phone to Samsung again for repairs, but i really don't want to be without it for 3 weeks if I don't have to.

 

Nokia N97 hangs and reboot

Besides the usual dodgey software which can cause this (which if you did, try uninstalling and rebooting first), other things can cause spontaneous reboots...



1. Running out of C: drive memory - look for other postings in this forum about maximizing your C: drive memory by:

• configuring your email to E: drive
• reinstalling applications to E: or F: instead of C:
• deleting unused files
• clearing your browser cache (and Google Maps cache if installed)

2. Memory errors on your E: drive which may have been caused by improper USB disconnect. Others suggest that you run a CHKDSK /F on the E: drive which plugged into your PC in Mass Media mode, followed by a reboot.



Good Luck!

 

Spontaneous crashes / reboots


Hi All,

I’ll start with a potential apology – my W10 PC is crashing – but not with a blue screen. I’m posting here because I couldn’t see anywhere more appropriate. [EDIT - there obviously was a more appropriate place & I see this post has been moved. Thankyou whoever fixed that for me!]

Background: I have a home-built desktop PC, which has been successfully running W7 Home rock solid since it was built.
Topline specs are:

• Intel Core i5-3570K 3.40GHz (Ivybridge) Socket LGA1155 Processor
• Gigabyte Z77-D3H Intel Z77 (Socket 1155) DDR3 Motherboard
• Patriot Intel Extreme Masters 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit
• Asus GeForce GTX 970 DirectCU II OC Strix 4096MB GDDR5 PCI-Express Graphics Card
• XFX Pro 550W Core Edition '80 Plus Bronze' Power Supply
• Crucial MX100 256GB SSD (for system)
• Toshiba 1TB SATA HDD (for files)
• Two DVD±RW SATA ReWriters
• 3.5" Internal Card Reader

Two weeks ago I allowed W7 to upgrade to W10. Initially it was quite unstable, but I uninstalled various bits of old / incompatible software and it improved dramatically. (Getting rid of Acronis 2014, which I gather is a frequent culprit for W10 crashes, worked wonders).

But the PC still has a persistent regular crash / reboot once or twice per day and I simply can't eliminate it. It’s not a classic ‘blue screen’ crash – the screens go black & the machine simply reboots spontaneously. Sometimes when it’s being used, sometimes when it’s unattended (I know it’s happened because Chrome has closed & offers to restore tabs when I reopen it).

Looking at Event Viewer (which I’m none too sure how to interpret properly at the best of times…) it says “The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly”
Source: Kernel-Power; Event ID 41; Task Category (63); Bugcheck codes all ‘0’s.

Here’s what I’ve done with no success:

• Opened up the case and reseated memory, graphics card, ATX cable, various other cables. A couple of weeks prior to getting W10 I’d installed a new internal card reader, which worked fine under W7 – but it occurred to me I may have disturbed something whilst I was in there. There was nothing amiss though.
• Windows Update is not allowed to automatically restart the PC.
• Turned off Fast Startup in the hidden Power Settings (following a YouTube instructional vid).
• Checked my video drivers are up to date (the GeForce Experience software takes care of this for me)

...and at that I’m kind of out of ideas. Looking online the problem seems very common, but with no definitive fix. I’ve considered that my PSU is failing, but it worked fine with W7, so I’m dubious about that.

I’d really rather not do a clean install of W10. Everything I read suggests that it doesn’t help, and I really can’t face the mammoth reinstall of all the family’s software. If it came to that I’d rather roll back to W7, which worked great for years.

But I do like W10 a lot, and it’s running well on various computers in my office, and on my just-for-fun Microserver at home. So I’d like to keep it on my main PC if I can make it stable.

I’ve attached a DM Log as per the sticky post, and will gladly add any more info / logs that you might want to see (might need to be told how to gather them…). Any advice anyone out there could give would be very gratefully received. Thanks for reading this marathon post!

cheers, Simon
