Connect the monitor to a different computer, to see if the monitor works at all.
Connect a different monitor to your computer, to see if your computer really is "sending" a video-signal through the "data" cable. If not, then either the data-cable or the video-card inside the computer is faulty.
Hi, I had the same inital problem as you, except I didn't put a new video card as I was please with the Onboard card performance that even has an HDMI port. Not sure if your problem is solved already, but in my working process, I first suspected the Power Supply, and I had everything out of the case but the Mother Board. When I tried to fire it up I was always getting "No signal" on the screen, not even a blink from the BIOS. I then put everything back in place, then after the HD started spinning of and Windows booting, the screen started coming on. I felt it was like if I needed Windows to have a clean booth to replace the video drivers and switch to the InBoard card. Hoping this of any help.
This means that the monitor is not getting a signal from the computer. The problem could be the video or graphics card or it could be the monitor itself.
Try to connect the monitor into a known working CPU. If the monitor works, then you need to check your video card.Try to pull out the card and clean it using a DRY clean cloth. And then re-seat the card to the slot. If nothing happen, insert the card into an available video slot. or try different computer. If same problem occur, contact the manufacturer.
NOW, if the problem is the monitor, check the cable, try to use different video cable. If same problem occur, then it should be checked by a technician.
The message input signal means no signal is being feed to the monitor. Check the cable use to connect the monitor to the video card.. fix and secure the connection. If the computer is reading and you know its working, check the video card. Turn off the CPU disconnect the video card from the motherboard and reconnect. Try to open your CPU and see if it reacts with your monitor. If nothing happens replace your video card
Please expalin how you know "drives are good" (sic) As it would appear to me that this is indeed your problem? Unless as you say the video card has turned up it's toes. As you said the best way to check that is to enable the onboard Video and check, exactly what happens when you do that? Yes it will automatically use the video, it would install a generic video driver,and show video, are you sure the monitor is OK,have you swapped it out? Simply removing the Video card will automatically enable the onboard video, so you won't need to get inro BIOS. Check the RAM too, and remove any other cards in it.
Besure that the video card you inserted are correctly inserted you need to check it first. You need also to installed the vieo card driver. If the sam things occurs you need to disassemble the unit . Try to remove the proccessor and clean it after that insert it again. Check all the power cord and cable wire if it is correctly install in their respective port.
I would start by trying a different monitor to eliminate the possibility of a faulty monitor.
if nothing happens you are going to need to investigate the video card. you can turn off the computer and open up the case and remove the power supply to the motherboard cord.
now remove the video card from the board and check to see that it isn't damaged or dirty . you can try to put it into a different slot if you are able to. now just hook up the powersupply cord back up to the motherboard and hook up the monitor to the computer and power up the computer than the monitor and see if it works if still nothing than i am sorry but you will be needing a new video card ok? i really hope that this is very helpful
best regards mike
The video signal is not reaching your monitor, check the pins on the connector from the monitor to the computer, then check the video card:
Turn off your computer, unplg the power, and then take out the video card. Wait 5 minutes and then put the card back into the computer and turn it on. For onboard video; turn off the computer, unplug the power, then hold down the power button on the front for 5-10 seconds, then plug back in and turn on.
Make sure the video card is snug in the AGP/PCI slot. If this is built-in video, try borrowing a video card from another computer and install it in this one. If the borrowed card works, then replace you card. If video is built in, then you can disble the onboard video and use the new card without having to replace your motherboard.
have you tested the power supply connection feeds? test each connector I think you will find your power supply has failed on either the 5 volt or the 12 volt side more than likely 5 volts are down' the agp adapter needs 5 volts to run. since you have changed out every thing else I would replace that or test your dads power supply in your computer, that should do the trick
