Pc gives no signal.

It's not video card

It's not monitor.

It's not ram.

Tried taking off all wires and plugging back in

I swapped my CPU, cpu cooler and psu with another computer and the other computer works but this one doesn't. Could I have damaged it while rebuilding? It was never on when I did.

You mean the GPU is tested working? Then it's the Motherboard for almost sure. Does it post? Just no signal? You tried hooking the HDMI to the GPU and the Mobo? Neither worked?

Specs?

Neither worked. Z270 and i5 7th gen. It worked before I swapped cpu

It all powers on and motherboard even lights up. But one fan does not work for some reason

It worked before you swapped CPU? Huh..

One fan not working is probably nothing. You've tried other monitors/HDMIs? You said it's not the RAM/GPU..

Try taking the Motherboard out of the case and setting it on a box? Usually if there's a short, it won't do anything, but I personally know one time a friend had the same symptoms and taking it out the case fixed it.

Did you try reseating the CPU? Double checked all connections?

Yes tried all of that but set the motherboard on a box??

The motherboard can get shorted out in the case.

You can try removing it from the case and setting it on a box or something. I actually had this issue on my first ever build but it stopped it from even powering on. Worth a shot though.

Otherwise, could be a BIOS issue. If you have another compatible CPU, swap it back. If the box doesn't work.

It powers on and even lights up. So CPU swap the last option ?

I know GPU works. Motherboard lights up and the fans move when connected to it. Says no signal

Try another wire for the monitor. Try booting up with no GPU, 1 stick of memory, and no hard drives.

What are the specs of your old and new computer?

What was the CPU swapped with? Did you update bios before install and then reset it by taking the coin battery out? Does the computer power up at all?

  • 21 months ago

Powers on. Same generation but i7. No there's no signal to see anything. I tried the coin.

I know you don't want to do this, but put the old CPU back. If it gets display this time, update the bios and swap it back. Reset bios after swapping tho

But on the other PC all I didn't have to do that. It just said new CPU installed

Well you gotta verify your board still works. Try putting the old CPU back.

Clickbait title... If it's not clickbait though I will happily take it.

First, make sure motherboard is plugged in, 8 pin CPU power and 24 pin.

Aren't Z270 motherboards Coffee Lake only?

Or is that Z370?

What I/O options do both your GPU and monitor share? What are you currently using, HDMI?

If so I’d try another HDMI cable first, then a different port/cable type - say, DisplayPort if both GPU and monitor have it. It’s entirely possible to damage a port without necessarily killing the hardware it’s attached to.
