New PC build won't post after 3 weeks of usage, VGA diode on motherboard lit


Jul 18, 2016
I recently built my first PC, it worked fine for the first 3 weeks, but stopped working last week. When I press the power button, all the fans kick on and stay on, but it will not post. After I push the power button the VGA diode lights up and stays on

So far I have tried removing a stick of ram and trying both sticks in each slot, tried switching to different PCI-E slots with my GPU, tried using a different GPU that I know works (I believe it was an R9 290x) as well in each slot, and cleared the cmos, with no luck.

Is it possible that the PCI-E slots are fried? There was a power outage once, but the PC was off and plugged into a surge protector, so I don't think that could have caused much harm.

Any help would be appreciated, I'm still new to PC building so It is very possible I made a mistake somewhere

Since the rig you built did work for 3 weeks, I trust your skills in connecting all as it should be. That, unfortunately, means you have a hardware malfunction. Since I doubt both RAM sticks died at same time (or all ram slots for that matter), and you checked 2 GPUs, this leaves us with only 3 components that can be the cause: CPU, motherboard and PSU. Simplest step now would be to borrow PSU from a friend and test your machine with it. If that changes nothing, you will be down to only two choices, and that's were problems begin. I doubt you have either another CPU or motherboard lying around for the test, and it's rather hard to determine which part is guilty without the test.
