[SOLVED] PC wont power on at all

[JupiXD]

Hi guys, So today I decided I wanted to upgrade some of my pc parts as Its been a few years since an upgrade. My Pc was working completely fine this morning before i took it apart and everything was functioning fine. I purchased a new Corsair Delta spec case, i7 9700 cpu, Corsair RM850x and an RTX 2080. Im using the Asus H170 pro as my motherboard, 16GB of Gskill ripjaws 5 Ram, 250gb Samsung 850 Evo SSD and just a WD 1TB HDD.

I put my new Cpu into the motherboard then mounted it into the case, i then started cabling everything up and got to the point of being ready to turn it on and give it a test. I plugged it in, pressed the power switch and nothing is happening at all. The only thing I can see that is showing im getting some sort of life is the green light showing up on my motherboard. I feel like ive tried everything to fix this problem, here is a list below of what I’ve tried and that haven’t solved the problem.

• Tried all available options for my IO panel to make sure the power switch is connected properly.
• Changed back to my i5 6500 cpu that was working fine this morning.
• Checked to see if Ram is in properly.
• Taken all Ram out and tested just 1 stick in first slot.
• Tried my old psu just plug in outside of the case into my mobo 24 pin and cpu 8 pin.
• Tested IO panel cables from old pc case into mobo in new case to make sure the button isn’t broken on new case.
• Checked all psu cables are plugged into the psu all the way.

I’ve been trying to fix the issue for hours but can’t work it out, hope you guys can help.

Well first, I can see one glaring issue right off the bat. Your new CPU is not supported on that motherboard: https://www.asus.com/ca-en/Motherboards/H170-PRO/HelpDesk_CPU/. While this likely won't cause it to fail to power on at all, once you do manage to power it on, the machine probably won't POST. You need a newer motherboard.

Second, with the LED on the board lighting up as you indicated above, you can try (very carefully of course) to manually jump the power switch pins on the front I/O header with something conductive. According to the diagram in your motherboard manual (https://dlcdnets.asus.com/pub/ASUS/mb/LGA1151/H170-PRO/E12046_H170-PRO_UM_V2_WEB.pdf) in section 1-22, the power switch pins are the third (power) and fourth (ground) in from the left on the top row. They only need to be connected for less than a second (think of how long it takes you to press the power switch on the case normally). At the same time, I would also suggest pulling the motherboard out of the case, and while still being able to connect the power cables from the power supply, sit the board on any kind of non-conductive surface you have available.

If that doesn't work, pull all of the components from the board (all ram, all expansion cards, all storage)... everything except for maybe a fan, or some other minor component you can use to verify visually or audibly that the machine is indeed powering up. If it starts powering on, replace individual components one at a time (one storage drive, test power, one ram stick, test power, another ram stick, test power.... etc.)

I wasn’t aware that my CPU wasn’t supported by my old motherboard so what would you recommend as a replacement for around the $300 AUD below mark? With my new case it comes with an RGB splitter part for the 3 front fans as well the single rear fan and 3 front fans all have a 3 pin connector that need to be plugged into somewhere on the mobo I imagine. This was a problem i found with my current motherboard anyway so I want to try and resolve this issue getting a new one.

also if jump starting the pc that way works then what does it mean, does it tell me that the case power button is faulty? Where would i go from there.

I appreciate your help alot, I know a little bit about PC’s but some of the indepth stuff i struggle with.

I found this one: MSI MPG Z390 Gaming Edge AC WIFI ATX LGA1151 Motherboard

Would this do the trick?

On it's own this could indicate a faulty power switch, but the reason I suggested that method to power up the system specifically is because I wanted to eliminate any potential for the board to make improper contact with the case somewhere and causing a short circuit (think extra motherboard tray standoffs installed where they shouldn't be). If indeed this does resolve the power issue, look for extra standoffs that don't line up with mounting holes on the motherboard and remove them. If that checks out, put the motherboard back in the case and reconnect the power switch. If it still doesn't work, reverse the motherboard connector for the switch. It won't damage anything when plugged in the wrong direction (as long as you did actually plug it into both pins for the power switch), it just simply won't do anything.

According to the MSI website for this board, your new CPU is supported as long as it is running BIOS version 7B17vA5 or newer (7B17vA7 is the latest version available). If the board did not ship with at least A5 (chances are fairly good that it will, but keep in mind that this potential issue might come up), the BIOS will need to be flashed first. If this is the case, flash it to the latest available version from the website. Unfortunately there is no way to guarantee that a given board purchased will have the necessary BIOS revision already flashed.

Checking out product images of this board, there appear to be several 4 pin fan headers distributed around the edges, along with some dedicated RGB connectors (though I honestly despise RGB and the craze around it, treating it as a waste of power and completely pointless aesthetic), but I'm not the best person to confirm if they will work for your setup.
