Random rebooting

[Lukep123]

Hey everyone,

My specs;

TeamGroup Elite Black 8GB (4x4GB) DDR3 PC3-12800C11 1600MHz (Currently only have 1x stick in)
Super Flower Leadex Platinum 750W Fully Modular "80 Plus Platinum" Power Supply
Core i5-4690K 3.50GHz (Devil's Canyon) Socket LGA1150 Processor
Z97-K Intel Z97 (Socket 1150) DDR3 ATX Motherboard
Samsung Evo 850 250GB SSD

(Graphics card not inserted into the PC yet or before).


Every single part is brand new, bought from a relible site in Overclockers UK.

When I first got all the parts, the PC began to reboot itself (Just turn turn itself off completely, no errors, just off), when I was installing the OS (Not in the bios), after trying windows 10 (At the installing windows part) it rebooted, Windows 8 the same, Linux the same, however, I managed to install Windows 7 Ultimate 64 bit (It did however reboot once during this installation, the second time it worked).

However, now the computer just randomly reboots. When I'm browsing the internet or click options in the bios.

I have already replaced every part and tested it (Apart from the motherboard for obviously reasons and the CPU).

The computer seems to rebooting randomly, sometimes just idle and sometimes when I preform a task.

I have already tried resetting the cmos to default, no GC, one stick of ram (And my other stick, in different slots).

There seems to be no overheating. All temps seem fine.

Mobo runs a stedy 19volts and CPU is running a stedy 22c.

Does anyone have any idea what the problem could be or what I can try to fix it? I have built PCs before and there isn't any missing pins in places or anything like that, I used thermal paste (a dot) on the CPU, all the basics, I'm really struggling because I feel I've tried everything.

Any help or advice would be really appreciated


Edit:

I forgot to mention, I got one error once, it said "There is a problem with the overclocking" or something like that, when I haven't attempted anything in that matter or changed any settings

Random rebooting is indicative of a bad PSU, usually.  As for the reliability, EVERYONE plays the lottery when electronics are concerned.  The companies that you buy are more important than the reseller.  Super Flower is one of the best and even they drop a stinker or two.  RMA it and get another, OR if you have another PSU available (borrow from a friend), swap it out to confirm.

I have bought a new PSU, yesterday and tried 2 other PSUs into the system. I don't think the problem lies with the PSU.

New has nothing to do with it.  Parts are sometimes faulty, even if they are brand new.  The next thing to look into would be the MoBo.  The power is being interrupted and that is the largest area in which you could have power problems beyond the PSU.  It's pretty clear that it's a power problem, so you have to work down the line.

I could not imagine my old PSU, which worked, my working PSU in my other machine and my brand new PSU all to be broken and causing problems, I feel the PSU being the issue could be ruled out.

The motherboard could likely be the issue.

I was more looking into anything I could do myself to try and resolve the problem. I know the problem is somewhere lying within the motherboard or the CPU.

The CPU is unlikely, but I never exclude anything.  You would have much more indications that random reboots.  Now the problem is testing your MoBo.  It may be hard to find someone with a spare 1150 board lying around so you may have to RMA that on the hopes that it is the problem.  

 

Do you have a personal connection to your supplier?  I made buddies with a few in my area and they allow me to test things with their equipment at times.

I was also quite certain it wasn't the CPU, the only issue which made me slightly think it could possibly be the CPU is quite often, it crashes when preforming tasks, such as clicking Firefox, I can leave it idle for 10mins, as soon as I click firefox it reboots. Although, sometimes it just randomly reboots.

I don't have an friends within the supplier, and I'm looking at about 30 days RMA return if I send it back when it may not actually be the problem which isn't ideal. I was more hoping anyone could maybe give me some tips or any insight to something I could try, I'm really hoping I don't have to send it back - but it's looking more and more likely I will have to.

I edited the post with a new error, it did say there was a problem with the overclocking, if you have any idea how I could possibly go about resolving that, if that's the problem.

Would anyone happen to know the correct (stable, not clocked speeds) for my CPU/Mobo I could try and set the speeds differently as it seems weird that problem would occur, even though I haven't actually overclocked anything.

OK.  Faulty OC warning actually could mean  the CPU.  Now you really need to make connections with friends, or co-workers, or face the lengthy RMA.  It sucks, but we have all faced this at one point, or another.  

 

Unless you are a computer engineer, you can't fix a faulty MoBo.

Thank you for the assistance. I will keep trying minor things to see if I can somehow stop the reboots, while it being unlikely and in the meantime hopefully someone can point me in any direction which may help, but it looks very likely it's just a hardware fault.

Wish I could, but the only people I know across the pond are not tech heads.

Did overclock the cpu before? or is it new and never been used... Also i would check in the bios for the voltages and temps of your cpu. It could be your cpu gets too hot and thermal shuts down. Also check ram speed. Make sure it is the right speed and it may not be a bad idea to lower it to like 1333mhz for stability. 

Nope, I didn't touch anything regarding overclocking, that's why that error is extremely confusing to me.

I will attempt that and have a look around the clocking speeds and try and lower them and see if it helps stabalise the pc.
