New motherboard and cpu. computer not turning on? [help!]

[suniced]

so i bought a new mobo - Z97 and cpu - 4690k for my computer. i installed both and my computer ran fine, before installing windows i realized that i forgot to backup my drive. so i put my old motherboard and cpu back in and did that. then i put my new parts back in and i got zero power, absolutely nothing. this really worries me because I've gone over the checklist and everything seems to be in place, the only thing i can think of is that i put the screws in the motherboard in different places and its causes a short or something. but I've tried different screw positions and didn't work. I've looked at using standoffs but i think my case has built in ones (and it worked without standoffs the first time) any help is greatly appreciated. thanks!

Here is a pic of my case, so the issue here is when i install the standoffs, it elevates my board too high and then none of the audio inputs or anything fit throughout the side of my case.

If there are no standoffs, it will definitely cause a short. Standoffs in the wrong place can also cause a short.

If you don't have standoffs, you are screwing the motherboard directly to the case which is bad.

Re-do the connections again, check all the power suppy connections. If you are not even getting lights or fans going you may have just hooked up the case power switch wrong.

i put in a picture of the standoffs on my case, ill try adding the brass ones in and test it. don't mid that one standoff in the pic, but my case comes with those bumps that i can put screws in.

Those are fine, they are built-in standoffs. What about the others further down by the expansion slots?

ok thats good, yea there are also standoffs by the slots. i tried using the brass ones and still no power. are there any other things i can test?

update - i put my old motherboard back in and the computer turned on. so maybe theres some thing not connected right with my new motherboard?

Try hooking it up outside of the case. If it boots outside of the case, chances are you have a standoff in the wrong place that is causing a short. If it doesn't boot outside of the case, you have other issues.

Also, make sure you have the extra power cable by the CPU plugged in, it's easy to forget about that one.

Thanks, I will try hooking It up outside the case. Can I just put it on a wooden table ? Or do I need anti static stuff

You can do it on the table, just be careful.

ok so i have just plugged the mobo in outside the case, and a small yellow light flashed on the ethernet box on the board as soon as i plugged in the power, but it still did not turn on. so what does that mean?

Assuming you have the speaker hooked up, pull the RAM and boot it up. It should beep like crazy, if it doesn't, it's a good indication that something is fried.

i just tried that on both of my boards and i got no beeps on either one, the thing is they were both starting up find a couple days ago. i doubt they could have got fried since then but i don't know what else to do. 🙁

Find out what BIOS it needs for that CPU. If it doesnt have the right BIOS on the mobo, it wont do anything

 

[cTs Corvette]

If you don't have the case speaker hooked up (not the speakers to your soundcard) you won't hear the beeps.

 

[suniced]

I only have one audio connector that comes from my case and that is plugged into motherboard. Since the board showed the yellow light, could it still be fried? Thank you for help so far! Any other ideas for me to try?

What Z97 mobo is it, and what brand?

It is a Fatal1ty Killer series

ASrock

Well as above if the mobo BIOS thats on it now doesnt support the CPU you installed. Its not going to work, until the right BIOS is on it

Interesting. What's weird is even with my old motherboard, which does support the cpu, doesn't turn on either. So I don't know what to do about that

 

[Paul NZ]

The prob is the CPU. Because its a haswell refresh CPU, which is recent. Most mobos wouldnt have the right BIOS on them to support these CPU's

The motherboard supports the CPU / is compatible with it. BUT the right BIOS has to be on it for it to work with that CPU

The boards were both working, but now they aren't, correct? That suggests that either your PSU died, or you are forgetting some fundamental step when you're hooking everything back up.

The speaker I'm talking about looks like this:

It connects to the front panel connectors, the same place the switches and LED's connect. Without it, you will not hear any possible diagnostic beep codes. It should have come with your case.

thanks for the response, yes the boards were both working. so i checked and i don't see that speaker anywhere! very strange. the only audio connector i have is this one -

 

[Paul NZ]

That goes on the mobo. If it didnt come with a speaker then you'll have to buy it. if you want one
