Hello everyone! I recently purchased a GA-EP35C-DS3R from Ebay and it’s behaving oddly. It stays on, lights stay on, fans run continuously—including the GPU fan—even when no CPU is installed in the socket. This strange power cycling happens repeatedly: it stays on for a few seconds, then shuts off briefly before restarting. I’ve tested it with several CPUs like Core 2 Quad Q9400, Core 2 Duo E6300, and Pentium D, but the problem persists. Clearing CMOS didn’t help either. My PSU is nearly new and 500W, and I’ve swapped out memory types (DDR2-800 and DDR3-1333) on a dual-memory board. Any suggestions on resolving this?

Consider using an alternative power source as a last resort, though it seems the motherboard might be faulty. If the seller confirmed the MOBO functioned properly, you might request a refund. Apologies if we couldn't provide more options.

I don’t have another power source, but I found something interesting! There are BIOS updates for this motherboard that mention compatibility with Wolfdale and Yorkfield CPUs, which seems to match what I have. It’s possible that without the update, my board might not work with those CPUs... But would it actually boot if I used an incompatible CPU?

It might be attempting to function, but lacks the BIOS update code, causing it to fail. Try it again and observe the outcome. The most concerning result is that it won’t work and you’re back to where you started.
