Motherboard light is Green, but my pc won't turn on

Please help me find the fix

I had the exact same problem. My tip is try to take out your RAM one by one, disconnect every cable in your PC like CPU, GPU and other and reconnect it. If it doesnt work disconnect your SSD, disk and other ♥♥♥♥ like this. Let only CPU, GPU, RAM just everything needable to start PC and than try. If it doesnt work one of this problems try to search on Google. Sorry for my bad English... :)

This is why you test it all, outside the Case first.
Everything for the PC can sit on a desk and use the Motherboard box that the motherboard comes in, as an elevated placement (for one the GPU can't install on flat surface) for testing the board and what attaches to it, all outside your PC Case firstly. I don't put the Motherboard and major stuff inside the case until after the OS is installed and it gets a good burn-in test. This is also how to more quickly identify issues, save labor time, and get the OS up and in running within minutes of unpacking your hardware. While the OS is installing, then unpack your Case and prep it.

Start from scratch, no cables just CPU in the socket. Connect the 20+4 power for mobo and the cables for case, especially the "speaker" and the power button. Try if powering on turns the fan and gets beeps. Then add ram, repeat. (aways turn off the PSU before doing any pull/insert).

Then add keyboard and connect monitor on the mobo, see if all beeps gone and you can get to BIOS setup. After that add ssd, hdd, gpu.

Yes all good info... basically your drives are the last thing to "connect" and try.
See that the system (the board + basics) boot and you getting in/out of the BIOS ok before going further. Most systems people try are Intel based, this means onboard GPU, try this firstly. When you do go to use a dedicated GPU card, seat it fully and properly along with any extra needed PCIE power cables, and then switch the Display from Onboard GPU to your new GPU card. The Display will run off of which GPU it connects to.

One of the most intimidating things when building a computer is the motherboard header connections for the front panel. I'm guessing you don't have the power on switch connected properly.

^ This too. LEDs on Motherboard will generally light on various models to indicate "stand-by" power is on, via the PowerSupply. You need the Case switch header to be correct if the power-on is to work. In a work-bench setting, we just trip the power-on via the header pins with screw-driver. Once touched it tells the PSU to Power-On and stay on. If after this the power goes out, generally there might be an issue somewhere. Some piece of hardware is not correct, or something might be wrong with Motherboard touching something, etc... this occurs to help prevent a "short" where power could be allowed to be forced through or damage anything. Most motherboards + PSUs have voltage protections of some kind to help prevent overloading + damages.

The easy/common mistakes I see are people using in-correct stand-off placements, where u have a stand-off in the case, touching a part of the back of the motherboard that it shouldn't be. This and the I/O shield not being aligned correctly and part of its metal is touching the inside of a USB port or Ethernet port, causing the power to trip off.

if fans DONT spin when you press power its either this or bad psu... if fans do spin but no post (black screen) its a component issue such as ram,cpu,mobo

But many are quick to assume a faulty hardware on that last part.
Many times on a brand new motherboard or GPU upgrade, the board might power on fully, but take a long time to post, this is due to internal reading of hardware prior to actual post.

Just an example of this; when I changed from GTX 570 to GTX 970 in a machine, upon having the 970 now present, it took a good 30 secs for the Motherboard to do this now first time post. After that though, it was fine and post timers were normalized.

yeah of course you would wait for it to post my comment is based on no post whatsoever.. also assuming everything is connected properly ie video cable is connected to video card if applicable, not mobo... for no post

I would geuss psu if I could have wattage of it I'll tell you if it's enough I would geuss it's not and you should get more wattage

[TheLemonSqueezer]

I have tried unplugging everything and putting it back in, and still nothing. Thanks for the help I just hope to fix it soon

Here are my specs

Here are the specs:
MB-Asus h81m plus
Ram-corsair vengeance x2 4gb
Cpu-Intel core i5 4570
Graphics card-nvidia gtx 750 ti sc
Power surply-corsair 650w
Hard drive-wb
1tb

I've heard a lot of negative reviews on Asus boards think you need a new board this time get a Msi board that can fit in your case

All brands have "cheap" boards. Those are usually the ones to avoid. Or that just happen to have higher DOA % rates.

Would you say the solution is a new motherboard?

[Bad 💀 Motha]

Might want to seek local PC Tech help to better determine if that really is your issue here.
If so, return or exchange the board within the return policy to the place of purchase. Or if PC Tech Shop has what you need, get one from them that is compatible for your hardware you now have, then refund the faulty board back to place of purchase.
