Troubleshooting after succesful boot and OS install

So I have "successfully" built my first PC, booted fine and installed Windows 7 all according to plan with no problems. I then shut the PC down to move it to a different room, turned it on but my monitor was just saying there was no display.

I tried a different DVI cable, an HDMI cable and an alternative monitor to no avail. So I opened it up and tried to see what was wrong, maybe something had come lose moving it to another room, but all cables seem to be plugged in properly and in the correct positions (I hadn't changed anything since transporting it). I then try turning it on again without any side panels to see if I noticed anything and saw that the case fans were not turning, but the CPU fan was working and so was some other LED's on the motherboard.. The video card also has a light green LED when turned on, indicating that there is power to it.

I then followed the troubleshooting guide on the motherboard forum just in case but everything seems in order. I have posted the spec's below and would really appreciate any insight you might have.

Video Card: Asus GeForce GTX 760 2GB DirectCU II Video Card
Case: Corsair 300R ATX Mid Tower Case
Power Supply: Corsair CX 600W 80+ Bronze Certified Semi-Modular ATX Power Supply

  1. If you take out the gpu and use the integrated graphics, does it give a display?

    I've been testing it more this morning and I have a feeling the problem either the motherboard/CPU or PSU, and the problem has to do with the 8-pin CPU power connection. If I leave this connector out, the PC turns on in exactly the same way as it does when the connector is in (CPU & GPU fans start, HDD & CD/DVD drive whir etc) which suggests to me the problem is either with the PSU's 8-pin power cable (not with the unit itself though, as the 24-pin cable is definitely providing power as PC won't turn on without it plugged in) or the the motherboards 8-pin CPU power socket.

    I'm leaning towards the motherboard itself being the problem as it seems the most likely component to break (what with all the force needed to attached some components!) but I unfortunately don't have any replacement components (PSU/CPU/Mobo/spare cables) with which to test which component is at fault! Any clever ideas about how I might test what's wrong with just the components listed above?

    Much appreciating the help!
  3. Try to see if the videocard is loose or the cable between the card and the monitor is loose. Here's a list of steps to follow:

    Even though you may have tried them, really the only option is to go through and retry all of them.
  4. Tried running without gpu and just on integrated graphics, still no display and case fans are still not running (they were running when I first booted the PC and install windows)

    Went through each step of the shortstuff guide and still no display or case fan motion. Interestingly the CPU fan is running fine, and when I turn the power off at the PSU switch the case fans both "twitch" and move slightly which suggests to me that it's not a power supply issue.
  5. I also tried running on just one stick of memory as I saw a thread where somebody was having the same problem and it turned out to be a bad memory stick, but still no display or case fan motion
