Monitor Not Receiving Signal From PC

[bsimon8]

I built a PC in December mainly for gaming and havent used it for about a couple weeks because I've been busy with life. Recently when I turned it on, both of my monitors did not receive a signal. Im quite certain that it isn't the cable to the monitor because both of them stopped working at the same time.

I've had some problems in the past of my computer releasing a loud noise through my headphones or the speakers and everything would freeze and I had to restart to continue gaming. I'm unsure if this is related to it but I did a stress test about two months ago and my computer didn't freeze so I don't think it is the motherboard or CPU. It might be the graphics card but I dont know for sure.

I researched this problem yesterday and took apart my computer and put it together to clean it and nothing happened. I cleared the CMOS, which I dont know what that it and probably should have looked at what it does before I did it but it was recommended as an option and it did nothing.

Please could someone help me get my computer running again, I would be very grateful.

take the videocard out & connect 1 of the monitors to the onboard video.

Thanks, but I already tried that. It made no difference. Does that mean its definitely my video card that isn't working?

as you still have to problem using the onboard video then the problem is not the videocard. try another psu as trying to eliminate the possible causes of your problem.
