Computer giving No Signal to monitor.
I read all the related issues and discussions here about this troubleshoot but unfortunately my problem is different
I had a pc was working fine for the last 2 months then suddenly just froze and when I restarted it gave me this message on the monitor (No Signal) so there was nothing wrong with the components or the cables or anything
I changed the monitor and all the cables it doesn’t work at all the same message
I changed the CPU itself with an old CPU and it worked fine so I thought the problem was my motherboard
But after 4 days I got the same message for my old CPU on the new monitor (No Signal)
I changed the monitor and it worked once and when I restarted my windows it doesn’t work again at all
The conclusion is changing 2 monitors and 2 CPUs and changing all cables the same error message (No Signal)

Any advices

Are you using an add-in graphics card or onboard?

I don'tknow exactly what do you mean but the both CPUs are built in graphics cards with two different brand.

If you connect your monitor to an input on the motherboard, that's onboard, if it's connected to an input lower on the back of the system then it's more likely an add-in card. If you're using the onboard, which it sounds like you are, it could be the motherboard itself.

There's no telling; you've gone through a good process of elimination: using different monitors, cables and CPU's. The only other logical piece to be swapped out is the mobo.

I'm inclined to say, replace your motherboard.

Thanks for your time but this is not a good advise though

You never said you used different motherboards, just different CPU's. It's perfect advice based on the information I initially received from you, until you now only mention that you've already used a different motherboard, which you should have mentioned several responses ago when I discussed the motherboard.

Your original post says you swapped the CPU and then figured it was your motherboard, so I assumed from that that you had never swapped the mobo.

When using the old CPU and a different motherboard you were still using a "new" monitor and cables?
