When I power on the PC all the thing is happening. CPU fan is running, Hard Disk is vibrating and CD writer is also responding but there is nothing on the the monitor. I reassembled many time the devices. I cleared the BOIS, RAM but nothing is happening. I see that problem not only in my PC usually this problem is happening in many PC but after some time when I reassemble, that PC start working but this time it is not working. So what could be the reason. Please suggest.

Thanks

its hard to say from a distance ,if you re-assembled the maching , if you have a addin video card as opposed to onboard video device make sure that the video card is plugged into motherboard correctly ,also make sure that the monitor cable is plugged into the correct place on the back of the tower ,

did you check your RAM is in place?place check it cuz it can cause also the same problem...or if you have installed video card even if your motherboard has a built-in video card,check it,and make sure that it is plug on the new video card(if it is being installed)

did you check the video card out thoroughly ...some video cards have a power dongle built in on the edge of the card .if you do not plug a rail into the card from the power supply it wont display the video
