Need help to solve stability issues on a newly bought rig!

I recently bought all my computer components so they are brand new. I experience crashes while gaming and while using benchmarking tools. This happens when my computer is running at stock speeds and also more often while slightly overclocked. It also happens after using default BIOS settings. After having troubleshooted my VGA, RAM, PSU and CPU I discovered that none of the components seem broken.
Every time I try to troubleshoot my computer from Control Panel - Troubleshooting - Hardware and Sound - Hardware and Devices the computer freezes and a reboot is required, with or without my graphics card installed. This also happens when I try to scan my devices from the Device Manager. At first I thought that my PSU was too weak or that my 780 Lightning was faulty but since the problems still exist even when I remove the card I'm guessing those are not the problem?
These issues also happen on my brother's computer, a computer that is identical to mine and bought at the same time.

This is my rig:

Right you are about the PSU probably not being the issue if you pull the GPU. Before assuming anything else, can you try running the programs which crash the computer after removing all but 1 stick of ram in the dimm slot #1/0 (the primary slot). Also unplug all motherboard headers other than power and reset, this includes USB, front audio header etc etc. Unplug all drives and optical disc drives other than the drive that the OS is installed on.

This is meant to get the computer to it's most basic configuration to reduce the possible sources of the issue.

From the sounds of it, there is an interrupt or error on the motherboard which is triggered when the computer attempts to access the hardware information. Are there bios...

how many sata controllers on that motherboard? intel doesn't play nice with some. read motherboard booklet and connect to alternate. ( this is for your SSD )

what happens if you reset cmos?

what are you using for sound? check control panel/sound and make sure it's pointing to that............ you can turn off auto driver updates and windows auto updates and then disable the HD HDMI sound from device manager to stop sound corruption(driver corruption)

are your motherboard drivers up to date......... or even installed ( off mobo driver disc)

is the heatsink form the cpu properly attached. even a slight cocking or a pin not securely fastened will cause crashing issues from heat ( yeah, saw that cpu temp you posted..... doesn't matter.) unless you see it in real time you'll never know the right temp.

has the firmware for the SSD been updated?

Is it possible to use the automatic overclocking utility in the bios and then test to see if the system is still unstable under the same conditions?

Thanks alot for your answers, they helped alot.
I did a stress test for the CPU and the temperature never rised above 50C so I'm guessing the heat sink is properly attached.
The firmware for my SSDs are the latest as well as my BIOS drivers.

What I think solved my freezing problems was that I unplugged all SATA cables except for my OS SSD. After some tests I identified that the problem was my Optical Drive. I plugged it in another SATA contact and it is no longer freezing while I scan for hardware changes!

Although 3DMark and games crash after a mild overclocking (overclocking the CPU is flawless) of the GPU so I'm guessing it might be a problem with the PSU, maybe too weak?

Oh sorry, I thought the PSU would show on the pic. I have a BeQuiet 630W Bronze. It should be a good PSU from what I've read. But maybe it's not enough for a clocked 780 Lightning and a clocked 4670K?

That should be fine still, unless the PSU is unstable, it shouldn't be lack of wattage. If anything, try using a completely separate PCIe 6/8 pin power connector cable for the second video card power plug, but the whole system shouldn't be pulling more than somewhere around 400 watts at full load during the benchmarks.

I have tried connecting a separate PCIe 6/8 pin power connector cable to my graphics card, just like you said but the crashes still happen directly after overclocking a little bit. My thoughts were also that 630W should be enough for my rig but maybe the PSU is unstable so I will try installing another one and see what happens.
Thanks for your answer!
