Answers :

Check monitoc cableing. This might be the cause of cable having loose connection on the back of the monitor. (I mean data cable (VGA) not power cable)
\015\012Did you have a chance to check with another monitor? Will picture appear when cable on the back is moved?
\015\012
\015\012Does this happen when you logon to bios screen? REstart PC and keep pressing F2. You will see bios screen - test unit there. If that is ok then everything is fine with the monitor.
\015\012Let me know if issue is not solved by checking cable and I will provide you futher troubleshooting steps.
