Computer Restarting Randomly

Hey.
 
I recently got a pre built HP computer (I bought it 3 months ago) that comes with i7 6700k, GTX 980 TI, 16 GB ram, and 256 SSD + 1 TB HDD.
 
Yesterday, there was a power outage for 5 seconds while the computer was on, so the computer shut down unexpectedly. I wanted to note here that I do have a surge protector and my computer was hooked up to the surge protector when the power went out.
 
Ever since then, however, something weird happens to my computer. When I'm using my computer and the computer isn't idle, everything works well, but when I'm not using the computer but it's still on, it stays on for about 10 minutes and then it automatically restarts the computer.
 
I've tried turning off the computer and then holding down the power button for 30 seconds (I've heard this might help in some situations). I've also tried turning off the computer and unplugging the power from it and leaving it off for about 1-2 hours, but the same thing still happens.
 
My guess is that something happened to the power supply, but it's very confusing because it works perfectly when I'm actually using the computer, but when the computer is idle it restarts randomly.
 
Anyone knows what might be wrong and could help me on this?
 
Thank you very much in advance.

 I don't know what the problem is, but you could take a look at the system event log for clues.  Download MiniToolBox and run it with the box checked to list the last 10 event viewer events and post the results here.

 

 In the future an investment in a UPS (battery backup) might be a good investment.  In situations like you had, it would let your computer keep running long enough to stay up through short power events or to do an orderly shutdown for longer ones.

 

 Good luck.


Make regular full system backups or you'll be sorry sooner or later.

Yeah I didn't know about UPSs before, and I've already ordered one, however I need to fix this problem at the moment. Thanks for the suggestion!

Hi,

 

I can suggest you some troubleshooting steps which might fix this problem.

 

1)    Unplug all cables and peripherals from system, press and hold power button from tower for almost a minute and the let it go. Connect only Monitor, Power Cable, Keyboard          and Mouse.

2)    Bypass the Surge protector, toggle the voltage selector and power switch from back of tower and restart the system without any 3rd party devices and observe the system.

3)    Try to find out in what time of idling system goes off

 

Please let me know, if any of this works.

Hey there.

 

I've done all three actually,

1) Did this 2 or 3 times, didn't work.

2) I've already bypassed the surge protector and have ordered a UPS to use after I fixed this.

3) It seems like it is about 10-15 minutes. It's somehow connected with the screen display going off (when the computer is idle), but I've tried setting the screen display timer to 1 minute, and I haven't been successful in reproducing the restart right after the screen turns off.

 

In addition, I was able to grab one of the dump files for the restart, and using windbg, it says that it's somehow connected to ntoskrnl.exe.

I had this exact problem. I forget the exact steps but I remember it was a fix in the BIOS. Search for issue plus BIOS. I built a custom PC using an Asus X99-Deluxe motherboard.

 It could be an overheating problem.  Have you checked?  Also have you downloaded and run MiniToolBox to get those errors from the system event log?

Good point about overheating! Definitely could be the problem.

Hey guys. I'm putting an update here. I did a system restore to a couple of days before this happened, and now everything is working perfectly!

 

Thanks for your help.
