AsRock Extreme4 Gen3 - constant rebooting

So I've just built my first machine (specs below) and it randomly powers off or reboots occasionally. Sometimes it boots straight back up, but other times it will not power on until I hit the 'Clear CMOS' button on the motherboard. Sometimes it doesn't even finish booting before it powers off again. I've checked the power connections, both the external one, and the ones connected to the components and they are all fine.

This is what I'm running:
Intel i5 2500k 3.3Ghz (currently at stock speed).
AsRock Extreme4 Gen 3 motherboard.
8GB Corsair Dominator RAM (2x4GB).
Corsair H60 cooler.
Corsair AX750 modular PSU.
Windows 7 Ultimate SP1.
Two SATA3 7200rpm Western Digital Caviar Green 1TB HDDs.
GPU has not arrived yet.

The fact it works when I hit 'Clear CMOS' implies, to me at least, that the problem is something to do with the motherboard. The UEFI (or whatever it is called) has been reset and I am running the board at factory settings, no changes anywhere in the UEFI.

If someone could help me out with this I would be really appreciative.
 
Yup. Every screw point is on a standoff. There may be a fan cable or something under the mobo, I can't remember. Do you think that could affect it? Also, should I try unplugging everything and removing the CPU, cooler, and RAM and then reinstall?
 
Haven't got a reset connector plugged in. It's not constant, I can run the machine for hours between it happening, but then when it happens it seems to happen often at the same time.

I'll try removing all the connectors, and also the CMOS battery to see if it works. It's difficult to test though, as the poweroffs are so far apart.
 
Can you explain a little why I should do this? I am fully willing to learn about things like this, and overclocking in general, but how will this affect my system? Will it run more stable with a fixed voltage than an 'automatic' one. It's currently running at 0.894V.

Also, when I get my graphics card, should I revert this back to auto, or keep it fixed at 1.20?
 
I think some are of the opinion that this board undervolts the 2500K when it is running at idle. 0.894V sounds very low to me, I don't remember mine getting that low when set to auto. Anyway a fixed VCore will prevent power saving from lowering it at idle, so if voltage is your problem then that should fix it.

The reason i say to try this is some people have had problems with the Asrock boards but mainly people who dont use a discrete video card but use the IGPU, it seems that the vcore is dropping too much and it causes the pc to randomly shut down and restart.
So setting the vcore to 1.20v may make your system stable or you could use a discrete video card instead.
Asrock have still not sorted the problem out and are not answering any emails or messages about this problem.
I have given up on the idea of using the igpu now and have had to put in a discrete video card in to cure the problem but its not what i wanted to do. Asus z68 boards dont suffer this problem just the asrock boards.
 
My igpu lasted about 5 minutes with this board and kept crashing. I then moved to dedicated gpu and it was crashing too. The motherboard just died with me. Never happened to me before, have lost confidence with the asrock so moved to asus Rog board
 
It does seem to be crashing mostly when I have tried to play a couple of games without a dedicated graphics card (World of Warcraft and Minecraft) so I think this might be true. I'm getting my graphics card soon which should hopefully sort this out then. Thanks Chippy for the great explanation. I'm now running with a fixed vcore of 1.2v and I will report back if I have further problems.

Go read thru this thread all people with problems with the asrock to see what is beeing said.

Wow. That really sucks. I don't know anything about any of the brands to be honest, but it's a shame such a popular board is causing so many problems.

As I said previously, I have upped my vcore to 1.2V and this appears to have solved my problem (after about 6 hours of gameplay it hasn't reboot once). Should I now try and lower that vcore back down a bit? To something like 1.1 or something, or is 1.2 a reasonable number to leave it at?

You can try to lower down but it might bsod again the only real cure is a discrete card or keep your vcore fixed. Im affraid Asrock seem not to care about the problem as they have been emailed and messaged with no response.
More and more people are finding that thread and reporting the same problem.
