For some time I've been experiencing some problems with my PC's performance. Unsure what it was about I have put it aside for a time until I would find a solution. Today though, I've experienced a severe problem. After rebooting my PC, it doesn't want to start up anymore! It gets to the logon screen (which I do) and then there is only black screen and a cursor.
I managed to get around the problem, go to task manager via alt+ctrl+delete -> run process -> explorer.exe and it DOES work. But it is a temporary solution, who knows what happens next, not mentioning that I am not really keen on doing it every time I boot my PC. What should I do?
