[Windows 10 64-bit] Odd sudden reboots - SOLUTIONS INSIDE

[Ilgoth]

I am in a desperate need of help with this.

I don't get why it happens and it is extremely random. My PC might reboot while playing or even watching Youtube. Constrain or not, it might happen. I am clueless what should I do.

Any suggestions? If you need any info, post down below.

What I have done already:
- Checked RAM with Windows diagnostics and memtest
- Drivers (all up-to-date)
- Temperatures are ok at all times
- Used command prompt to run "sfc.exe /scannow", system32 is all good

On the "Search Windows" bar - type "Event Viewer" (without the quotes) and select from list.

From that go to: Event Viewer (Local) > Custom Views > Administrative Events

Look for red error messages around the date/time of those crashes. You can ignore most warning messages and there might be a lot, don't be too alarmed. This event log contains a records of all activity (errors/warnings) and by click on them gives a General/Details tab below.

Note don't the error code(s) and/or root cause.

When Windows 10 crashes and reboots it also should mention a filename or error code - note that down too, if found.

This should give you some idea where to look and what you are dealing with.

What Web-browser are you using? If it's rebooting on Youtubes (flash content), try disabling Flash content and seeing if that helps running it as HTML5 base?

Check: What does this browser support? Then check the video codec it's using and ensure that's not corrupted or an invalid version.

Most of the time PC simply shuts down and restarts, no BSOD or anything.

Once I got BSOD and it said "APC Index Mismatch"

specs?

post a cpuz validation link
http://www.cpuid.com/softwares/cpu-z.html
cpuz -> validate button -> submit button
it will open a browser, copy the url (address) and paste it here

and power supply (brand/model)

[Azza ☠]

On the "Search Windows" bar - type "Device Manager" (without the quotes) and select from list.

Do you have any drivers with a yellow triangle or question mark? Right-click and update drivers on them.

If that doesn't help, right-click it > Properties > Details. Under the Property dropdown list, note down the "Device Description" and "Hardware ID(s)".

One thing I noticed that is claims my GPU is AMD Radeon HD 7800 Series, when I can quarantee the component inside is AMD R7 265, 2GB GDDR5.

My PSU is: SST-ST70F-ES Silverstone 700W, Strider Essential

-----------------------------------------------

Azza: Yes I've checked these devices and the drivers. I couldn't find anything to upgrade and it didn't recognize new drivers. But I used Driver Booster 2 and that found 3 old drivers (one Realtek, then USB driver and some third I have no idea).

Random shut downs and restarts are usually associated with overdrawing power or overheating.

Make sure your power-supply has enough watts and amps for your system.
...It's not only your cpu and gpu that draw power....
Do you have adequate airflow through your case? (perhaps add another chasis fan or two)

Blue screens can be caused by many things.

Have you tried re-seating your video card(s), ram, and cpu?
Double check to make sure that all connections (power and data) are firm and secure.

Hi Delta,

yes my PSU should be ok. I double-checked when I ordered new parts in January. Also my classmates from programming field confirmed this build should be ok.

My PC went just fine for almost 7 months with no issues at all, but now it started to fail on me. I started 8 days ago and I was using Windows 7 back then. With no solution, I decided to upgrade for Windows 10 Pro and clean installed as well. But problems are still there.

It started as an error message, everytime I booted I got "This driver can't release to failure." Found out that Gigabyte's app EasyTune 6 was the cause and removed (no error ever since). But then I got these new issues that I've described here earlier.

---------------------------------------------

I have reseated my RAM, but haven't tried GPU or CPU yet. I also could try checking those cables.

I was just playing Minecraft for fun and PC completely freezed. Had to shutdown and reboot, no mouse or keyboard was responding.

Increase your CPU voltage by 5% or so, it might help with your issues.

Hey Tabris, this is first time someone suggests me to do this. Any risks I should know about? And its done in bios right?

[[AU] Tabris:DarkPeace]

Yeah, in the BIOS usually.
You might need to press [Ctrl]+[F1] at the BIOS MAIN MENU to unlock certain 'extra' options as a security precaution.

A +5% bump to CPU voltage is nothing to worry about, you might need to look up your current CPUs default voltage and figure out what 5% is than add that +#.### Volts in the BIOS.

Assuming your motherboard even lets you do it. (Most do).

There could be something going on with the power grid or the house circuit you're plugged into.

Interesting thought. I do live in a 8-storey-apartment building.

If power related...

Kernel Power (Event 41) - Suggests the PC restarted without a clean shutdown. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Since power is critical and can be damaging if unchecked, might want to check that first.

Ensure to of first: Disable overclocking and ensure nothing is overheating.

For testing purposes, while your PC is left running a graphical process (stress testing video card or in a game) - turn off (wait just a bit) then back on other unrequired high voltage gear (such as subwoofer if you have one). Check if the issue occurs when another device is turned on/off (such as the air conditioner or washing machine, etc - even in other rooms or apartments). This might cause a spike in voltage, which drops the voltage going to your motherboard temporary, causing it to shutdown or reboot - specially if you have multiple plug connections all off the same power socket. It can also cause audio speakers, amps and subwoofers to make a "pop" sound.

If this is the case, and your power is quite overloaded and/or dirty, consider a power conditioner. Try avoid retriggering that event, if running without one.

This is more than just a basic power surge protector. I personally use a "Furman PL-PLUS CE", which is designed for audio gear (my electric guitar, amp, and axe fx effects), but also run my PC, monitor, surround sound, subwoofer and other devices through it. This isolates each power cable (each cable connector is sold separate to fit) with it's own stable, clean power and protects from voltage spikes/drops. A bit of an investment, but ideal to have if you use a lot of electrical gear. It can even protect you from a lightning strike. It also covers the gear with about $50k insurance and audio clarity is improved (as no more electrical noise/interference).

If driver related...

Download your latest drivers (don't install yet, just place them in a folder to use later).

Motherboard drivers (Gigabyte 970A-UD3P):
http://www.gigabyte.com/products/product-page.aspx?pid=4717#dl

Graphic card (download AMD Catalyst Software Suite):
http://support.amd.com/en-us/download/desktop?os=Windows+10+-+64

Reboot into safemode (Normally F8 upon booting to get boot menu / Or in Windows 10 - Hold down Shift key, while holding down, open the Start menu and click on the Power button > Restart).

Update and run a "RootKit" scan to ensure the Windows Operating System and drivers haven't been injected or affected by malware, such as using Spybot (Free version):
https://www.safer-networking.org/mirrors/

Once scanned and deem clean, install the latest drivers (clean install) you downloaded before, while still in safe mode (Safe mode will ensure secure software doesn't block it, which is why we also virus scanned beforehand). Then reboot back into normal running of the system to test.

Thanks @Azza for long post!

I just added 5% increase to CPU voltages. Before it was 1,3625 V, now its at 1,4250 so roughly 5% increase. Will let you guys know how my PC reacts to this change.

If this didnt do the change, I will look into the power cables and consider getting power conditioner.

Could these problems be PSU? Like, maybe it has started to break up but not just yet?

[Ilgoth]

Alright I just crashed, so it didn't solve it. But it did last longer to crash.

Before, PC simply went black and shutdown itself and rebooted. With higher voltages, it went black screen but didnt shutdown - instead it gave electrical buzz noise and I had to shutdown it myself.

I have now defaulted voltages back where they were.
