Wondering if anyone out there has had this issue. I can't seem to work it out. The computer turns on but no display, this happens randomly and sometimes the PC loads up fine. Occasionally when i'm playing games it's like the buttons on my monitor are pressed and the options appear then the monitor has turned off. I’ve had on occasion the computer totally jar up with an annoying sound then restart. At first I thought it was my monitor as the buttons on the monitor were unresponsive. I’ve tested it with another monitor and i’ve had no display on that one too. MOBO next ?
