Unfortunately I am back with a new problem .. and seeking for some much appreciated guidance.
So here's the problem..
Lately pretty much every time a turn on my pc, the screen does not turn on. It stays completely black with no signal.
I know it goes all the way to desktop because I can login without having to see the screen and I can even turn the computer off using the normal method because I also know the key sequence to turn it off (windows key - tab - 6 down - enter - 1 down - enter) and the computer goes off.
If I turn it on again.. the screen will stay black again. The only method that works is:
disconnect the power cable - turn it sideways and open it up - look at the insides with a very menacing and desperate look - sometimes touch the pcie cable of my gpu to make sure it's well placed - reconnect the power cable - turn the pc on - and voila the screen comes back to life.
Sometimes when I try to turn in upwards after seeing that it is working fine and with the pc still on, it crashes and restarts but comes back on with everything still working.
Also, on very few occasions (very very rare!) while playing (only happened during Overwatch) or browsing, it restarts on its own but there is no bluescreen nor error of any kind displayed. I have a software called WhoCrashed and there is no blue screen logs or anything.
Lately I have also noticed that sometimes the computer takes longer to make the mobo beep sound right after I turn it on.
Side note: It used to be OCed but not anymore and it already wasn't before these problems started happening.
