Specs of the computer: CPU: AMD A10-6700 Motherboard: Acer AAHD3-VC RAM: Kingston 8GB DDR3 (CPU, Mobo, and RAM are from an old prebuilt) PSU: EVGA 500B HDD: Seagate 500GB The computer works fine without the GPU (a Club 3D R9 280X) when it is using the iGPU for display, it has windows installed on it and can play games on very low settings. However, the issue we are having with this PC is that as soon as we insert the Graphics card and plug it in, there is no display from either the motherboard's iGPU or the GPU itself. The fans of the GPU spin up indicating that the GPU is clearly working, yet it just doesnt display and for some reason doesnt let the iGPU display either. We have tried the following for troubleshooting: - Going into the bios settings without the GPU (didn't really help cause stock acer bios gives no way to disable the iGPU) - Trying the GPU in a different PC (worked perfectly fine, displayed and was able to run games) - Resetting, and then replacing, the CMOS battery of the motherboard - Installing the drivers of the GPU (R9 280X) onto the hard drive using the iGPU I assume that if it was a problem with the pcie slot, like if the slot itself went bad, the GPU would not spin up so I don't think it could be that. And I used to use my current GPU (A gigabyte R9 380X) with this motherboard before so it most likely isn't a compatibility issue. Does anyone have any ideas here?

Well I cant fully deny its a short but I'm using my old motherboard in my case rn and have been doing so for a year and it works perfectly fine, however this one is mATX. Could the fact that I only had 3 screws of the usual 8 screwed in to the STRIX have to do with the short issue?

Just to be clear, the first board did not work at all. At first I tested it outside of the case and nothing.

For the first motherboard I tried building it outside of the case and it did not work, for the second one I tried and it worked fine and I put it in the case, used it for quite a while, went to sleep, and the next morning it was not working. I've tried breadboarding with the second board so the case is likely not the issue, and if it was really a short that damaged the motherboard I don't think that the RGB lights on the motherboard would light up like they do whenever I flick on the PSU.

I recently purchased an ASUS B350-F Strix motherboard for my new build but had to RMA it because I had thought it was not turning on, and ASUS ended up sending what I believe to be a new one. It turns out I had forgotten that I need to short the PWR_SWITCH pins on the motherboard to get the cpu fan to actually spin up, meaning the one I had before probably was not defective. Regardless, after receiving the board again, I finished the build, powered it up, and everything was working fine. I played a few games of PUBG and then went to sleep, but when I woke up the PC was not turning on anymore (I had shut it off the previous night). Thinking it was a loose connection that probably fell out, I opened up the case, made sure everything was connected properly, and disconnected the front panel PWR_SWITCH connector that was working fine the night before and tried shorting the pins with my screwdriver. However, the same thing occurred, and the CPU fans did not spin up. The Motherboard RGB and the orange light at the bottom of the motherboard turn on like they're supposed to (ASUS makes it so that they are always on as long as the board is getting power) but nothing spins up when I try and actually turn on the PC. I have tried using a different power supply, taking out the GPU, unplugging the PSU connectors, as well as bread-boarding the build, but nothing seems to be working. Can anyone tell me what the issue could be? Thanks!

The RGB is simply built-in rgb that turns on whenever the motherboard has power, and the bottom right orange LED is there to indicate that the board is receiving power

Yes, I've connected the GPU properly and am using the CPU cable to plug into the motherboard.

Tried removing RAM, the exact same thing happens.

Parts list: https://ca.pcpartpicker.com/list/kJMPbj What I've done to try and fix it: I've tried rewiring everything, I've tried using another power supply, using different ram slots, and using different pcIE slots for the GPU. However, I still cannot get anything to post. The RGB on the motherboard as well as the little orange light at the bottom right lights up, but the GPU lights don't light up, the GPU fans don't spin, and neither does the CPU fan. One note of importance might be that the pins on my PSU's 2x4 pin CPU connector don't match the ones on my motherboard, but they plugged in fairly smoothly with a little bit of force anyways. The pins on my PSU look like this: while my motherboard's connector looks like this: http://cdn.overclock.net/0/09/096b4849_Asusmaximusviiformula.png. I searched that up online and it turns out that the PSU maker (EVGA) decided to key only one side to save money, but I figured i might as well include it just incase it has anything to do with my issue. Any help is appreciated. Thanks!
