Sudden PC turn off without warning then stuck in reboot loop

[JohnTHDW]

This happened to me before and I thought It was caused by a game. It happened today in the morning with a game but it also happened this afternoon when I was just browsing, nothing intensive. The computer just goes black without any sound or warning, then restarts and stays in a reboot loop and it won't start. I tried the "fix your computer" options that appear but it stays in the reboot loop.

To make it start I have to click turn off computer then restart manually, then starts without problem.


As soon as it happened I went to event viewer and got this:

Here are my system specs:

Motherboard ASUS M5A97 R2.0 AM3+ AMD 970



Any solutions? this never happened when I had windows 7 🙁

The two most common causes for boot-looping are a overheating CPU and a failing PSU.

If you have a questionable quality PSU, that's likely your problem. Doesn't hurt to check for a overheating CPU first though.

 

[R_1]

what is your power supply? do you have a spare to test with? Kernel power stops are USUALLY a power supply issue. if you do not have a power supply to test with you can try booting to a linux drive or a bootable CD. verify that the power issue is happening in a new environment, if so you can be fairly sure the issue is hardware related.

 

[JohnTHDW]

I don't think is the power supply. Actually I replaced a Cooler master 550 to a

XFX ATX12V/EPS12V 650W


Also temps seems normal

[JohnTHDW]

Temperatures are OK, all fans are working, memtest test OK.

Today suddenly turned off twice and the second time the computer didn't want to turn on, I had to wait a few extra minutes then it worked again. Any suggestions?? 🙁

If the computer plays dead after randomly shutting down, that sounds like something tripped the PSU's over-current/power protection and the PSU went into lock-out mode. Either you have something pulling too much current, the PSU is defective or simply doesn't like one of your components' behavior.

The strange thing is that this PSU was recently replaced for a:


XFX ATX12V/EPS12V 650W

Funny thing this never happened when I had windows 7, all these problems only when I updated 🙁

Does the boot-looping happen in the BIOS or at some point while/after loading Windows? If it happens before Windows begins booting, then the OS has absolutely nothing to do with it.

I will check again if or when it happens again and I will make sure but I think it's after because I believe the Windows logo loads.

 

[JohnTHDW]

Today the PC turned off the first time while playing s steam game and the computer rebooted to windows without problems. I went to play the game again and turned off after 30-40 mins playing, this time got stuck in the restart loop and it's after loading the windows logo.

Temperatures are fine.

If you have a PSU air filter, check that and make sure that the PSU itself is also clean. A clogged PSU air intake could cause the PSU to overheat and shut down after some number of minutes, boot-loop, then boot fine again once it's had a chance to cool down a bit - until it gets to warm up and shut down again.

Have you tried the system in a new environment like linux?
Have you tried the system with the 550W power supply?

No
I don't think a 550w PSU would be an improvement.

 

[R_1]

not an improvement as a test of the 650 unit
put in the old and see if the reboots continue, if so the issue is definitively not the power supply? one less thing to look at. replace with the 650 knowing that it is good.
if trying the system in a new environment yields no reboots then the issue is probably software related(Driver,etc) inside windows that is causing the issue

 

[InvalidError]

No
I don't think a 550w PSU would be an improvement.

If the reboots started after you replaced the PSU, it could be a defective PSU or perhaps you nudged something while swapping the PSUs out and a loose connection somewhere inside is causing power issues.

No, I replaced the PSU more than a year ago,, pc was working perfectly, the problems started when I upgraded to windows 10, basically after the latest updates🙁

Is the BIOS updated? You might need one to work with Windows 10.

Although it sounds to me like your PSU or motherboard has failed. Power delivery is surging somewhere and causing the system to shut down to prevent damage.

Your VRM's could be overheating as well. Put your finger on the big blue heat sink to the west of your CPU while your under heavy load. Are they burning hot? There's your problem.

If you're confident these issues only happen because of Windows 10, than don't worry about it. Update the BIOS or update the drivers. If still doesn't work, switch back to Windows 7.

That could be the problem, it needs BIOS update but just thinking about it makes me scared of damaging the motherboard, lol. Is updating a big deal or something I could do without problems?

I have never considered BIOS updates a big deal. Then again, I've always had an UPS to make sure untimely power interruptions couldn't cause problems with those. Updating from Windows may be a little risky but most modern BIOS support updating from the BIOS screen, so that eliminates the OS from the equation.

For the most paranoids, some motherboards have dual BIOS images so you can flip to the backup image after bricking the other one or even a micro-controller tied to a specific USB port which you can use to unbrick the BIOS by simply putting a BIOS image file on a thumb-drive and rebooting.

I wouldn't recommend it unless you are 100% certain that your PC doesn't randomly reboot from BIOS first though.

Update:

For the last 2 days computer was working perfectly, I played yesterday for 1.4 hrs, then today I played for almost 2 hours, no turn off or reboot, these last 2 days the weather have been cold and humid, I also left the computer side panel opened.

Then today, while browsing the internet I got the sudden turn off, then reboot loop. Probably is irrelevant but today is hotter.

Then I proceeded to clean everything with compressed air, made sure everything was properly seated then I found the motherboard ATX cable not fully inserted and tilted to the side. I pushed it back in and put everything back together, so far working good. Could that be the issue? a loose ATX cable that caused all this mess?

 

[InvalidError]

An intermittent contact can cause all sorts of issues. Worst case, it can cause the pins to overheat and the connectors/wires to catch on fire.

 

[JohnTHDW]

Surprisingly all this problem was caused by the ATX motherboard connector that was loose. Now the computer is working perfectly, no reboots. Thanks everyone!
