Solved

Computer monitor went to sleep during gaming, wasn't overheating no visible issues. Now upon start up it says no signal.

It's happened before, I didn't use the computer for about 2 days and when I turned it on it was working. Even switching PSU's and graphics cards the problem keeps persisting. Which is probably a motherboard issue. I've reseated everything in the computer, dusted and all that. Cleared the CMOS battery. And cycled the power. Solving this would be with a new motherboard but I need a short term fix for it.

I have changed to a HDMI cable from a DVI. My monitor is a HP x2031, 1920x1080 @ 60hz (not 100% sure on the model). Tried both a 500w psu and 750w changing between a 550ti and gtx 670. Both still present the same problem. On start up all fans are spinning and the light on my usb keyboard goes on as well as the Windows start up sound playing.

Nothing out of the ordinary was happening, game was running fine. Temperatures were all fine too.

I'm really clueless as to what to do here.
Could anyone help me out?

    I tried the monitor with a laptop and that did the same thing. So it must be the monitor. I couldn't try a different monitor with the pc though.

    why not? Since you have hdmi a tv should do as a temporary monitor. Unless the only one(s) you have are huge and not portabe like monitors.
