I blew out my desktop with compressed air and now i have no video. the screen acts like its going to work and then says monitor going to sleep. I had it checked out at a pc shop and the said it is probably(?) the mother board. got an exact replacement from HP and still dead screen. changed out the video card with a new one still nothing. Any advice as to a reasonable fix $wise would help.Also when it is first turned on,(cold start) the cooling fan for the processor runs at full speed and the only way to shut off the pc then is to unplug it.

Do you here any beeps when attempting to start the computer? If yes, Then in what pattern do they occur?(How many long beeps and how many short beeps?)

Since you've replaced the mobo and video card I would say to check your monitor.
