Question Weird PC problems

[midnightrunner]

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 ? Cheers

I'd start with reinstalling the graphics driver personally. But... do you have a graphics card? You don't mention it in your PC specs or post.

Sorry yeah I forgot to mention it's a Nvidia GTX980 TI. I've done that but i'll do again from scratch and see what happens. Still doesn't explain the monitor buttons, maybe it's just unlucky thats going as well.
