I’ve encountered several issues with my recent setup and made some adjustments along the way. The initial steps involved replacing the power supply, but once it started booting, there was no display or HDD activity. When I removed RAM one at a time inside the case, the system would spin fans briefly but wouldn’t respond. Switching to a different motherboard didn’t help much—it only showed a short fan spin before shutting down. I also tried using a new GA-H97-HD3 board, but it failed within seconds. My only clue was the CPU; I removed it carefully and still faced the same problems. I’m worried about damaging the board further and fear I might have caused permanent issues. I’m considering swapping in a 4690 if it’s the real cause, but it seems unlikely all four sticks are faulty. Any suggestions would be really helpful. This experience has been frustrating and time-consuming.

The Clear RTC jumper removes both the battery and power source from the chip responsible for storing settings, causing them to vanish after a short time. When you activate the PC using this jumper, it won’t cause damage; the chip won’t save any configurations, and the BIOS might fail to recognize prior settings. In such cases, simply detach the power cable from the supply unit to prevent the board from drawing power from the 5V standby mode, ensuring the chip retains its data. Then, remove the small CR2032 battery from the motherboard—press the clip on the side to release it. Without any battery, the power supply won’t provide energy, so the chip will lose its stored information regardless of the jumper setting. After reconnecting the battery and power cable, wait a few seconds for the chip to reset. Once stable, reinsert the battery and power cable. To verify everything works, remove the motherboard from its case and inspect for any electrical shorts on the back or other parts. Place it on a non-conductive surface like cardboard or books to block current flow. Connect only the necessary cables: the 24-pin connector and the CPU-specific one, along with a RAM stick in the correct slot as per the manual. Insert the RAM according to the recommended position—usually farthest from the CPU socket. Since the CPU includes integrated graphics, link the monitor to those connectors. Try booting by briefly connecting the PW_ON pins on the front panel connector for a moment, using a flathead screwdriver if needed. Make a brief PWR-to-GROUND connection for a few seconds. To power down safely, short the PW_ON pins in the front panel connector for at least 4 seconds. If the system starts, press DEL or F1 to enter BIOS and choose defaults, then adjust settings. You can add more RAM sticks and test if the board boots successfully. For memory testing, create a bootable USB with memtest tools available online.
