The Asrock X99 Extreme6 stopped turning on unexpectedly.
I purchased the motherboard about two years ago because it wasn’t working. I adjusted the BIOS chips and managed to get it running, though I’m not sure if I mixed things up. It was used in a server environment for roughly a year, then sat idle for about six months until recently. I removed it from its case, cleaned it, and placed it back in a standard case. After reconnecting everything, I entered the BIOS, made some adjustments, saved the changes, and turned it off using the PSU power button. The next day I realized I hadn’t updated any settings in the BIOS. When I powered it back on, it started up but didn’t illuminate any LEDs, the Dr. Debug screen was blank, and there was no display output. I moved it out of the case and tried again, but nothing changed. I attempted to reset the CMOS, changed BIOS versions, swapped in different chips, and even used another CPU and RAM sticks, yet nothing worked. The processor gets hot, but it seems communication between the BIOS and hardware is missing. It does receive 3.3V power, and I tested three different CPUs and three RAM modules, but no response. Could it be that shutting it off with the PSU switch actually caused it to fail? I’m unsure what to do next.
Last year a Fujitsu Esprimo E910 (an older i5-3470 model) experienced issues after I connected a SATA drive. I verified the boot sequence in BIOS and realized the drive was plugged into a 3Gb/s port, so I turned it off using the PSU power switch. Since then, it hasn't started properly—only the fan speed increases gradually. The power-on indicator lights up, but no functional response occurs. I attempted to reset CMOS, swapped RAM, and tried another CPU, yet nothing resolved the problem. It seems switching the drive to a 6Gb/s port might have caused the failure, though that’s unusual since it works elsewhere. My suspicion is that shutting it off in BIOS disrupted the system.
