On another machine, delete that win 7 install on the boot drive and re install it and try again. Or try form a disc if you have access to a recovery disk and a cd/dvd drive

Maybe im missing it but i dont see anywhere in this thread that youve tried either.

First thing, Paperclip test your PSU. This is simple. Secondly, Bread Board your system with only the bare minimum hooked up. CPU Cooler, GFX if you dont have on board graphics, and your PSU of course as well as only one stick of RAM in slot 1. You'll need to use a flathead to short your power switch on your MOBO. Hopefully it'll boot!

Have you tried bread boarding your system to rule out that your board isnt being shorted? I had this same issue last month and it turned out to be a USB header from my front panel that was shorting my enitre system. Try booting while bread boarded with just the bare minimum hooked up.. PSU, GFX (if you dont have on-board video) and your CPU cooler as well as just one stick of RAM in slot 1 (check your mobo manual). Hopefully it'll boot!

I do believe there is an option in the "display" setting that will disable your monitor going to sleep in any instance. Look into that. Display setting in Control Panel and not your monitor's on-board settings that is.

Consider using a friends PSU to test your system and see if it boots and runs reliably. Thats step 1.

PROBLEM SOLVED After a new MOBO and PSU it turned out to be a faulty USB front panel cable that was connected to a USB header on my mobo that was shorting the entire system! Who woulda thought...

I've already replaced the mobo I over-nighted one yeaterday and is still producing the same results. Which leads me to believe it could still be the PSU. Is it likely that a PSU that passes the paper-clip test could still not power on the system? Please help! Haha. thanks!

Hello all, please help if you feel you may know whats going on with my system. I woke up yesterday morning, tried to power on my PC and... NOTHING! I checked all power connections, switched to a different power socket and surge protector. Still nothing. 1-So my first test was to see if my PSU was dead. I paper-clip tested it and to my surprise the PSU power's on and the case fans connected through Molex powered on as well. 2-I then thought maybe there was a power surge that managed to short my board, I over-nighted the same MOBO and installed it today and to my surprise again... NOTHING! 3-I disconnected my 2nd memory stick, leaving only one in the board, disconnected my drives as well as my discreet graphics card and am now trying to power only the MOBO... NOTHING.. Not even the slightest hint that the system wants to power on 4- I tried to power on the system by shorting the power pins on the board and this method also did not work.. The build: Board: Gigabyte 970-DS3P PSU: CM G550M (My 2nd one as my 1st was DOA) CPU: FX 8370 w/ wraith cooler. GFX: EVGA GTX 960 2GB (Yes, this was a budget build) & 2 sticks of corsair vengeance for 8gbs total. Could this still be a PSU issue ? It did indeed pass the paper-clip test with flying colors as I mentioned earlier so I cant be sure And since Ive just bought the same mobo again id hate to have to buy another PSU. Any suggestions would be greatly appreciated as I'm going a little stir crazy over here. Thanks!
