Halp. Today I cleaned out my pc with some computer duster and afterwards I went and plugged everything back in. I then turned on my computer and everything sounded fine but my monitor was not picking up the computer. I dont know what is wrong. My monitor never had any problems before. Any help would be greatly appreciated.
 
if your pc has onboard video see if that on. sometime if there a issues with the gpu the motherboard can fall over to the onboard video port. if it did power off and check that the video card is seated and all the power plugs are locked in. also check that the ram is seated. if the gpu still wont turn on go into the bios make sure the primany display set to peg/pci. if there no video try clearing the cmos with the power off and resetting the gpu.
