Does your PC have a Graphics Card or is it using On-Board graphics?
To find out, look at the back, if the Monitor is plugged into to a Card, in one of those Slots, then switch everything off and move the connection to the Identical Socket in the area where all the MoBo Connections are.
If it is a Graphics Problem most Monitors display a Notice saying "No Signal" or something of that nature. So I think that, barring a simple solution, it has died.
You can buy yourself a lovely Monitor for about £120.00, all models will work with your PC so long as they have both Analogue & Digital Connections. You easily can spend more, or less, as your budget allows.
I got a lovely 24" Samsung that will do me for years, for £115.00, but it's currently running on my 6+ year old, Windows XP, Self (with professional assistance) Build PC. I keep meaning to buy a new PC, but this one does everything I need, so I will not replace it until something makes that necessary.
