This issue started a couple months ago when my computer (specs below) went black screen, "no signal" (for the first time since it was built) when I tried to boot up a game. It was pretty scary because I didn't know what it could be, mobo? gpu? psu? etc. Turns out all I had to do was unplug my GPU from the PSU. And use my internal graphics card on my mobo to boot up. Once there I ram the AMD http://support.amd.com/en-us/kb-articles/Pages/AMD-Clean-Uninstall-Utility.aspx clean driver utility, rebooted once. Then shut down my pc, plugged the gpu back in and bingo it started up again. Once I was running windows on my main GPU I reinstalled the drivers and it was smooth sailing from there. "Phew!, so it's just a driver issue", I thought.
And then it happened again, and again, and again. At one point my little trick didn't work anymore, and in a moment of desperation I took out: the GPU, the mobo battery and my one stick of RAM, waited 10 minutes and put everything back. And then it worked again, and then it broke again. After the so many-th time I was looking at forums and I found a trick on a forum where I could hold down the power button with the PSU unplugged (resetting the cmos). This trick works as well. But the issue is becoming more and more frequent. Today it was multiple "no signals"+fixes in the span of a few hours. So I guess this really is a "bleeding computer".
Here is the current state/issue:
1. Sometimes I turn it on and I will see the Gigabyte logo screen, then after a while it will go black screen "no signal", but the computer will keep booting up. I can press the power button (once) to safely shut down.
2. Sometimes I power on and see nothing, black screen. Then suddenly out of the blue the windows logo will appear, as if the GPU wasn't sending signal yet and then suddenly jumps in at the last moment.
3. Sometimes I power on and see nothing for a looonng time, and then suddenly I see the windows log-in screen. (This rarely happens but usually occurs after wiping my AMD drivers)
4. Sometimes I power on and everything goes smoothly. But it looses signal at random moments, ex. starting up a game, starting up steam, even just starting up spotify will cause it sometimes. However, it has never occurred mid-game, maybe just a coincidence though.
5. Sometimes I power on and get absolutely nothing, not even a "no signal" screen, just blackness. (This usually occurs after number 4 and I am forced to reboot)
In ALL of these cases the GPU is powered on, the fans are spinning (at least at the start) and nothing seems to be wrong with GPU. Yet the screen gets no signal.
When any of these issues occur I then do the following fixes (in this order, if one doesn't work I go to the next):
1. Unplug/turn off PSU, hold down power button for a minute. Reboot a couple times until it works. (this usually does the trick now)
2. Unplug gpu, use integrated graphics, reinstall drivers etc. (as stated above)
3. Take out GPU, RAM, mobo battery, wait 10 minutes. (as stated above)
Up until now, one of these three methods will always solve the issue temporarily. At first I was blaming windows for screwing with my drivers, because the issue would always start up again after a windows update. But like stated above, it's becoming so frequent now that it's just ridiculous, and I don't think it's just windows. Either something is in a bad config state, or some hardware is seriously failing. The most likely culprits are GPU or mobo. I doubt it's the GPU because at the end of the day it still works and runs my games at good FPS as it always has.
I hope there is something I can do like reinstall BIOS or use a special driver cleaning tool that can fix this issue. I'm prepared to buy and reinstall new components but I would like to exhaust all other options until I make a stupid decision like replace a working part.
I know it might be the screen, or the cable. But it coincides too well with always working again after a cmos clear, I can reboot as many times as I want, it won't work. I do a CMOS clear, it immediately works again. The cable is very high quality (like super thick and newly bought) and the screen is always receiving power when it needs to, power light is always on etc.

Any extra info I can give or diagnostics I can run, ask away, I will do those tomorrow and post the results
