PC keepa restarting

I have recently built a machine, processor intel i3-6100 3.7ghz, gigabyte h110 mobo, Kingston hyper x 4gb ddr4 Ram, seagate hd 500gb. Corsair 450v smps. Installed windows 10 it worked fine for 4 hours and then the machine started restarting. After crashing on booting back it comes up with gigabyte and then restarts again sometimes it might show the windows 10 welcome screen but crashes again. I kept it off for the whole night the next morning i turned it on it worked for 2 hours and then started restarting again. I don't know whats going wrong please help...
 
I wouldn't expect heat to cause rebooting in a modern i3. Did you push the RAM in so it locks on both ends of the stick?

Is this an old case? My next suggestion would be to remove the power switch connector from the motherboard and try booting by briefly touching a screwdriver to those pins on the motherboard.

I still think the PC rebooting after 2-4 hours could be caused by the CPU getting too hot. I rarely use the stock Intel heatsinks in my builds, but I used it for my son's Haswell i3. I pushed all the tabs down and turned each one in the direction of the arrows. After double-checking everything before powering it on, I noticed in my motherboard's manual that is what you do when you want to remove the heatsink.

Since I didn't start it with the heatsink not making good contact, I'm not sure how hot it would have ran.

OK, you're right, it could be heat. [thread=2478409]The guy who didn't use a heat sink on his i5[/thread] had more problems than I remembered.
 
Oh, I remember that thread. In fact, I still have an occasional nightmare from it. 😉

Gotta love the "I need help" posts where they argue with everyone.
 
I feel the same too but how can i tell its a heat issue i tried touching the heat sink the motherboard, ram and dey dont feel hot at all.
 
I would recheck all of the power connectors to make sure that they're completely seated on the connectors. You might try running memtest to rule out the ram as you systematically search for the cause. Did you plug in the HSF fan to the motherboard header and does it spin when you start the machine? Do you hear any weird sounds from the ps or is the exhaust air really hot from it?

That was gold! Thanks for the link as I had missed it previously. Gotta love the experts. I mean, sometimes even we "experts" miss something ourselves. But to be willfully ignorant to standard practices. I once had a neighbor who was in IT. Was having problems with his computer rebooting. Took a look and found his HSF was not securely mounted and a cable was not seated properly. Lost a lot of respect for the "IT" guy. Not running a modern CPU without a HSF. Must be true because I saw it on the internet!
 
Might be a dumb question, but did you remove the protective plastic on the heatsink before attaching it?

It's basically the job of a heat sink, to get hot. :biggrin:

If it's not getting noticeably warmer when the CPU is working hard, then there's a problem.
 
Why not run a stress test that will for sure get the CPU warm, and see if it can pass the test? You can run the Intel XTU Stress test for a start. It's not too hard on the CPU, but it will heat it up.

If it passes the stress test, then it's probably not a heatsink/fan problem.
 
Could also be the vid card overheating. I had an 290x that kept doing that. Had to manually kick off the fan a bit higher with afterburner.
