So my computer recently will turn on but the monitor will stay blank (Power saving mode) for some reason. I tried a different monitor, does the same thing. I thought it might not have been getting enough power so I bought a new power supply, still doesn't work.
I am wondering how I can test to see if it is the video card that is defective? If it was the motherboard the computer wouldn't even turn on correct
Its most likely a video card issue.
If you have onboard video(ie. a video-out plug on your motherboard) then plug into that and see if it works.
If it does, you need a new video card.
If you dont have onboard video, get a video card from a friends computer and stick it in and try it.
