Hello everyone,
Long time since I was it these parts of the woods due to work and life in general, but I need your help again.
So let me jump into it: I recently upgraded my build a bit, from an i5 4670k to i7 4790k, and R9 380 to GTX 1080 (forced by cryptomining, no RX580 available after I already sold my old GPU), and my case from a Silverstone SUGO SG09 (SFF) to a Phanteks P400s TGE.
Based on this, I was thinking to go for a full ATX mobo, and get rid of my m-ATX Z87mx-D3H, but I`m out of money after all the other upgrades.
Now, I found a Gigabyte Z97X Gaming 5 for sale, but for parts, for under 15$. Ad said it was booting for a second, and then would turn off. I had the same issue with my current board, where the BIOS would get corrupted, so removing a RAM stick would allow me to get to BIOS and reflash it, which would fix the issue.
I hoped that the same trick will do it with this board, but with no luck.
I started with a breadboard test, with just the 24pin and 8pin from the current PSU, the CPU and a stock Intel cooler, with NO RAM, keyboarn, mouse and a monitor. this would give me a continuous short beep until it would reboot.
Adding RAM (regardless in which slot, or which stick) would reveal the problem of the motherboard: turn it on, mobo will light up and fans are on for about 3 seconds, reboot, turn on for about 10 seconds with a successful post beep, and reboot again in this 3sec - 10sec loop.
The only thing displayed on the screen in the 10sec part is an underscore on a dark screen, with no chance to see bios or flash a new one.
Adding a GPU with the monitor connected to it had the same result. The only difference was if I would remove the 8pin PCIe from the GPU, which would give me a message along the lines of "PLEASE INSERT THE PCIe POWER CABLE IN THE GRAPHICS CARD"which would stop the reboot loop. Inserting the PCIe cable back would make it continue to reboot, so again no chance to get to BIOS.
Did some research online, and found 3 methods to switch to the Backup BIOS (no dedicated button on the mobo). None of them had any effect on the way the motherboard acts.
I did do a visual inspection of the mobo, and I can`t see any bent pins on the CPU socket, damaged capacitors or cracks/scratches. It looks pretty good visually.
Any help or advice would be highly appreciated. I`m thinking if getting a multi-meter tester might help, but I don`t know what to look for, so if you can share any information here, that would be great.
TL;DR: -Bought cheap damaged mobo. Reboot loops of 3sec/10sec (with post beep but no display). Unable to switch to backup BIOS. Need help!
