I recently blew out my pc with a compressor 110psi (dumb, iknow now) then when hooked up to monitor, no monitor. cooling fan started running full on and power switch does not turn pc off, i have to unplug it. Took to a pc shop they reseated all the components and diagnosed it as a mother board.(the weird part is, they said it is "probably" the motherboard???) bought an exact HP mobo replacemant and installed it, still no nonitor. one thing i noticed was when i powered up, the on/off button for the monitor is orange when off and blue when on, would turn blue for a few seconds and then turn orange again as though the monitor is off. I did blow out the cooling fans and the blades did turn fron the comp.air being blown over them.My monitor is hooked up to a DVI input the computer is an HP d4100e desktop. see this page: http://h20141.www2.hp.com/Hpparts/Search_Results.aspx?mscssid=92B7675C69A644CEB4951A06B49597CB&SerialNumber=mxg60902vc&ProductNumber=PX191AV
