Black screen after "Welcome" window

Hello everybody,

So basically today when I wanted to turn on my PC after Welcome window, instead of seeing my desktop, i saw black screen and my mouse cursor. Nothing can do, windows key/ del+alt+ctrl. So i restarted my PC i entered safe mode, restarted from there, nothing happened. Eventually after another 3-4 restarts and same black screen, I entered again in safe mode and turned PC OFF from there. After waiting 1 min, i tried to turn on my PC and this time it worked.

But this is like 2nd time when it happens in less then 1month (previous went fine after first restart).


What can cause this problem?

PS: Excuse my English.


Thanks in advance,

I understand. I freaked out abit, I thought i'll be forced to format my pc


Thanks for answer,
