I have a HP 2009M. Windows Vista 64 bit. 4 yrs old.
I can turn my computer on fine, check email, watch videos, etc. but then the monitor screen will go black. The blue power button stays on. If I turn off, and back on. It will work for like 5-10 min or so, then it will be a black screen. If I am watching a video when it goes to a black screen, I can still hear it playing. I do hear a very faint buzzing sound coming from the monitor which I never heard before this happened. Is it my desktop or do I need a new monitor?
