Computer reboots on intense loads!

When ever I'm doing something like playing Battlefield 4, it would reboot after 10 mins.The time varies on what I'm doing. A less demanding game would reboot in about an hour or so.

My specs:
Cpu: I5-3570k
Gpu: Gtx 760
Psu: Corsair Cx600
Mobo: Gigabyte-B75M-D3H
RAM: (Stock) 8gb
HDD : 1TB
Chassis: Thermaltake Commander MS-I Edition

Help!
 
Update: It just rebooted while playing Battlefield 4 but oddly enough it was running fine when i was in a lobby with just 6 people but then i joined a 64 lobby and it rebooted after minutes( if this helps at all). Help!!!!

The more players you have in a game, the more hardware intensive it gets. That's why "old" gen consoles were limited to 24 players in previous BF games. My best guess would be your CPU is overheating.

Download Prime95 and, run the torture test "in-place large FFTs" and see if it crashes. If it does, your CPU is most likely overheating. Prime95 is not supposed to crash your computer if it's working properly.

Running a temperature monitoring program at the same time should help you see if it overheating.

Prime95, select the proper version for your OS:

Realtemp, a temperature monitoring software:

Is 90C the temperature for your CPU or your video card. It's still high for a video card, but WAY too high for a CPU..

How long do i run it and right now my temps dont go past 90C

I have the exact same CPU, Core i5 3570k, and it doesn't go above 66C even after hours of running Prime95. Granted, I do have an amazing HSF, the Noctua NH-U12P SE2, while I'm assuming you're using the stock Intel HSF, but I doubt it would make for a 25C difference.

As for how long, my temperature is the max registered after running for 24h(last time I did it, not right now), but since Prime95 is pretty CPU intensive, it shouldn't take any longer than the time it takes for your computer to reboot when you play BF4.

Granted, your video card also produce a lot of heat, which increase the case temperature(and the cpu's), but I doubt it would make that big of a difference with a good case.
 
Im glad people actually care about my problem 😀 not like "toms hardware" where it takes days for replies and soo any ideas of the source for the problem.

I don't come here that often, I only have around 500 posts, but I do keep coming back, even after being a member for almost 15 years now. AnandTech's forums are the best!

As for your problem, seems like the source is your cpu, as to why, right now, no idea but cleaning up the dust in your case might help a lot. Also, make sure the fan is running all the time on your CPU. Intermittent fan failure, coupled with your already high temperature, might explain why your computer keeps rebooting.

Did you install the HSF yourself? Do you know how to do it? It might not be installed properly and might need to be reinstalled(with fresh thermal compound).

It might also be a good idea to test your video card. I'm sure there are more intensive GPU testing tools out there (Furmark might be one) but Unigine's Heaven can push your hardware to the limit and is pretty easy to use. Launch, set everything to maximum and let it run non stop.

The only problem with that test is that, well, overheating GPU don't force your computer to reboot, they make it crash... So I don't know, running both Prime95 and Heaven at the same time might trigger it. If it does, we'll know for sure it's heat related.

Well then, a processor overheating it is. The excess in heat produced by your video card must put too much stress on the CPU's HSF.

As stated in my previous message, for now I recommend removing the heatsink for a fresh new install with new thermal past.

I also recommend cleaning the inside of your case and all your various fans and heatsinks to remove all the dust. Use compress air, be it in a can or with a compressor, don't use a vacuum cleaner.

PS:Just to make sure, do one last test first. While a modern video card's GPU should throttle down when overheating to keep it from burning up, it shouldn't never prompt a reboot. Try running Heaven without Prime95 to see what happens. It's not really CPU intensive and should not cause it to overheat. If my theory is correct, it should confirm that the CPU is indeed the culprit.

Just ran Heaven and no reboot. Hmmm so your theory is correct?

What is the exact model for your video card? Is it a blower type cooler or open case cooler?

As for my theory, let's just say we're getting close. I'm pretty sure the CPU is overheating, now I'm trying to figure out why.

Answer this please; was your computer always like this or did the problem began when you changed something, like the video card, or, did it start to act up for no apparent reason?
 
At this point in time, you have established that you have a heat problem, so further testing at this point isn't helping anything. If you continue to use your system in this state, it IS going to damage something (probably the longevity of your CPU, as Ivy Bridge processors aren't that tolerant to overheating in my experience).

If you are using the stock heatsink, make sure that the retaining pins are all still properly seated and locked. It may even be a good idea to consider a good 3rd party cooler -- you might even want to make a day of it and clean everything out while you are at it, including the shrouds and fans on your video card as well as case fans. It doesn't take a huge amount of dust to significantly degrade system cooling, especially if it is in the wrong places.

I agree, if it wasn't clear in my previous post, no other testing is required or recommended at the moment, I was merely asking questions that can easily be answered without performing more test.

I would still like to get an answer for those questions. We know it's overheating but we don't know yet if it has anything to do with dust, a defective unit or something else, hence my questions.

I don't recommend buying a new HSF just yet as the current one might just be dirty or not properly seated(right word?).

Better stick filters or cover up unused intake vents on the front/side/bottom of your case.

From what I could read on his case model, all the intakes already have filters. I wouldn't recommend covering up what you call unused intake either, at least not from what I can see on the pictures. Assuming it's not a badly designed case, all the intakes, including the ones without fan, seems to be needed for proper airflow.

The dust filter is only on the psu. There are a few unneeded fan intake grills that can be covered up safely if a fan is not installed.
- bottom grill (no filter) which can pull dust up from the ground into the case
- 2 top grills (no filter) which allow dust in and can short circuit proper airflow for the rear fan
