so my specs are:
Asus Z87-Pro
16GB Gskill RAM
i5-4670k
GTX 780 GPU
900watt PSU
so I built my pc about a month ago and had no problems but recently when I power it down the next time I boot up it keeps shutting down and booting up in like 5sec intervals, when I unseat the ram and put it back in it boots up. I have ran the windows memchk and it says the ram is good so I could use some help please

You can't really test your memory with Windows running. Download memtest86+ as an iso image, burn it to a CD and boot from this to test. Allow it to complete at least one full pass, which will take at least an hour.

Saying that though, your power supply seems like a more likely culprit. What is the brand and model of your power supply?

It is a very good supply, and rated much higher than you require with a single GTX 780 card.
That doesn't mean the power supply isn't faulty of course, but at least we've ruled out a rubbish supply.

RAM issues would usually cause a blue screen of death rather than a freeze. Temperature issues could cause windows to freeze or shut down. Maybe use some software to display CPU temp.

It is always a good idea to install the latest driver too of course.
