A couple of days ago my computer completely crashed whilst finishing a game of csgo. I had to hard reset it to get it out of the crash state. Once turning it back on I could not get past the windows logo. I've had this problem before and fixed it by uninstalling the nvidia drivers in safe mode and reinstalling but for whatever reason this does not work for me anymore. I've been trying various things over the past few days and nothing seems to work bar uninstalling the nvidia drivers and going from there. I've tried updating windows, reseating and changing PCI slots and have just tried it on a fresh install of windows. I am quite certain it's not a hardware problem as I managed to fix it before. I am currently running an evga 660ti on windows 7.
 
I keep a scratch hard drive (it is an older 320GB drive), and a USB stick with Windows 7 ISO loaded on it for situations like this. Easy to swap out the hard drive, boot from USB and install Windows 7. If all works well, it is not hardware.

More than likely, when your computer crashed - it was writing a file to the hard drive, and that file is corrupt - it can be anything from a registry key, drivers or other Windows system files.

I would recommend backing up any and all important data first. Then try the following things in order (stop if it is fixed):
1) Repair windows installation - this should attempt to repair the current installation: http://windows.microsoft.com/en-us/windows7/products/features/startup-repair
2) Reload (same as an upgrade) your windows operating system - this will rename your windows folder to windows-old and require you to reload all of your programs, and copy your data back to the proper folders
3) Wipe the drive, and reload from scratch - needless to say, you lose everything on the drive when you do this....

I have just encountered the exact same problem, did you get it fixed?

@ronintexas Although what you say is good advice, 5ix has already stated the he has reimaged windows to no avail.

I am a pro user and can't get this fixed. I too have done all the usual troubleshooting techniques from the basics of unplug/replug cycling, reseating ram and only using one stick, running disk checks and memtests, reseating the GPU, different cables and monitors etc right through to downgrading my bios (as I remembered there was a recent update) and attempted various downgraded versions of the Nvidia drivers.

The old fix for this issue would be where the bios or driver would force the on-board graphics to become default so just changing it to the pci slot in bios or in control panel/screen resolution would force output through the GPU. This can also occur when multi-screening or changing between port types i.e. hdmi, dvi, vga etc
No chance of that in my case as there is no on-board graphics output at all.

To my displeasure I am leaning towards a GPU fault as output is fine at a native resolution whilst installing and configuring windows but as soon as the nvidia drivers are installed 'No Signal' is shown, indicating a problem pushing a higher resolution. This includes straight from a clean install and attempting the GPU driver before anything else.

I have had this exact setup running for months, fault free, in 4K and getting decent fps on ultra settings without ever overclocking. I have a 980 gtx on win 10 but have even tried it on win 8 and 7 with no luck.

The only thing I am yet to try is the displayport over the hdmi in case either the port has broken or there is an hdmi handshake issue, unlikely, but I have a dp cable coming soon to try.

If/when this doesn't work I'll be stripping down my build and breadboarding it to see if anything has been fried.

To cut a long story short it was the refresh rate.
My tv supposedly supports 60hz but would only work when I plugged in another monitor and turned the tv down to 30hz.
