Good Morning, I recently got my computer back from repair, for a completely different unrelated problem (I hope)...and I've had it back less than a month, but I've run into another problem.
I was on it as normal one night, playing games, on youtube, answering emails etc. The next morning, I booted up my PC and it got to the motherboard splash screen, but got no further. My computer will not post, I got no beep code errors, and no error messages, both my screens just go black. At one point, I managed to get it to the desktop and continue to use it as normal, but once I shut it down, it would not boot at all.
Of course, I tried using only one stick of ram, unplugging all peripherals, and rebooting, but to no avail. I have now sent the PC off for repair, and instantly, they spotted the problem; my four pin CPU power cable was unplugged. I know that a computer will not POST unless this is connected, but I do not understand how my computer's power cable came out seemingly overnight.
My specs are below:
CPU: AMD FX-8320 Black Edition @ 3.5GHz
PSU: OCZ ZS 750W Non Modular
M/B: Gigabyte 970A-DS3
RAM: Corsair Vengeance 16GB DDR3 @1600MHz
GPU: NVidia GTX 780Ti SC (EVGA)
Cooler: Corsair H100i
Boot SSD: OCZ Vertex 120GB
HDD: Seagate Barracuda 1TB
OS: Windows 7 Home Premium 64-Bit Genuine
All the fans run, my hard drives spin up, and my screens flicker on briefly, sometimes they will crash on the MOBO splash screen. I have my data backed up, but will I have lost it on my primary drive?
Any advice or information would be much appreciated!
Thanks

There is no reason that your data will be lost.To clarify, is that your only question? Or is the computer still not working?
Okay, Thanks for the reassurance about my data. I should have been more clear with my question; the computer is still not working apparently, according to the guys who are fixing it. I want to know why this happened, why my power cable disconnected, and also if this is something that could happen again, i.e. a motherboard related problem.

Okay. There is no reason for your 4 pin cable to become disconnected. Frankly, if the computer didn't move at all, then it is impossible - there is no reason for the cable to just jump out of its socket. I would suggest using some electrical tape to attach the two plastic sections together so that it doesn't come out again. Your PSU and motherboard should clip in on the 4 port anyway - has the clip broken?
We'll need some more detail to know why your computer isn't working - is it just random what happens? Sometimes it boots, sometimes the fans don't even move, etc...?

Okay, that is one problem solved, Thanks for the info, will try this when I get it back. I was not aware that the clip had broken, I will take a look when it comes back, I had considered this initially. So that rules out the possibility of it blowing out. This has never happened before, the computer was one hundred percent fully functioning until that morning, it always boots, the fans always work, because I run corsair's CorsairLink software as a fan controller. My HDDs never break, and I've got no corrupt data as far as I knew.
A friend of mine told me that this is a problem with the Gigabyte Motherboards, also ASRock motherboards. But I don't know if this is true? I'm running the 970 chipset.
Thanks for the info so far!!

No problem Volta13! I am still a tad confused as to what the problem is - the computer does not turn on? Have you tried it when the four pin is completely clipped/taped in?The computer will turn on, but it will not go past the motherboard splash screen, no login screen, no desktop, nothing, The screen will freeze on the motherboard screen, where it has the gigabyte logo. I didn't realise that the four pin power connector was out, so was oblivious to this aspect until I took it for repairs.
On taking it for repairs, the guy put the connect back in, and tried to turn it on, but said that it would not get past the motherboard screen. All my components will power on, but that it all, they do not seem to work together to get past the motherboard screen.

Okay. Have you tried the following:- booted with one RAM stick (try each one on their own)
- removed power, removed BIOS battery and reset CMOS (page 15 of your manual), then put battery back in, power back in and boot
I won't be able to reply to you until tomorrow morning.
Yes, I have tried booting with one stick of ram, also, I changed the CMOS battery a while back, so that should not be the issue. However, I cannot clear/reset CMOS via Keyboard commands, because my keyboard only lights up momentarily, and no input can be given, my PC just won't respond. Can't even get to boot menu, to load defaults!

No problem. You can update this thread when you get it back, or feel free to PM me
Thanks for all your help, I just got a call from the people who are fixing it, apparently it now boots fine, and goes to the desktop every time, no problems?! It must just have been that 4 pin cpu connector, although I'll have to secure it with some elctrical tape when I get home!
So I should be getting my system back tonight, and I will try to remember to update this threaf on whether it works xD Once again, you've been great for all your input, Thanks man.

Did they give you a reason for the issue? - Sounds like your Motherboard is the fault.Funny you should say that, just got off the phone with the tech dude, and he basically said it would be my motherbaord, and that the fault has just returned, what he called an 'intermittent' fault. 28 working days for my system to be stripped, and a new identical/repaired board of similar chipset (970 AMD) to be sourced from Gigabyte.
Could be a voltage problem apparently, I have a faulty fan as well, which he noticed that the pins were damaged and that this could be trippping my system. Will update you ASAP!

Gigabyte 970A-DS3 is a low end AMD 970 chipset motherboard that does not support the FX-8320 Black Edition.
http://www.gigabyte.com/support-downloads/cpu-support-p...
There is no heatsink on VRM (voltage regulator modules) on this model, no fan cooling VRM modules. Using the 125 watt TDP (Thermal Design Power) unsupported CPU may have damaged the motherboard. I doubt this kind of damage would be covered under warranty.

Your PC fixing people seem to change their story an awful lot... are they reputable? Can you take it away, send it somewhere else and see if they come to the same conclusion?I thought this as well. The company are reputable, and I know that they do a good job, but I can see where you are coming from and appreciate your concern. Unfortunately, I would take it somewhere else, except this place has my system under warranty, so it is cheaper. I know this does not always mean that it is the best option though!

That is the most interesting and helpful answer I've received so far actually! It didn't occur to me to actually find this out for myself, but this is not the first time that I have been led to believe that the 970 chipset is low end. Thanks for the information, so from this, can I say that the people who manufactured my PC, actually dropped a 125 Black Edition CPU into a board which does not officially support the 125W CPU Model (although it does support other 125W cpu models, these are lower specs than mine, I don't know if this makes a difference).
I understand what you are saying about warranty, but these people built my computer, I chose the CPU, GPU and OS, they chose the MOBO, so technically, it's their mistake right?? One more question, why has my pc been working okay for a year, under these conditions? I'm just wondering what sort of damage this may have caused!
