Hi All. If you need help, let me know if this isn't the right place. My ASROCK H81M HDS motherboard is likely around 7 years old now. It probably won’t power on at all. I was using my PC normally, then went away and came back to find the keyboard unresponsive—even when plugged into USB 2.0 ports. Everything worked fine with USB 3 devices like my mouse, external drive, and phone. Moving the keyboard to USB 3 resolved the issue. After a restart, the system booted without errors. The USB 2.0 port on the motherboard remains dead.

I turned off the PC, disconnected the power supply, then left it on for a few minutes to clear any residual power. I swapped the CPU, RAM slot, tried different power switches, reset the PSU, and even used a screwdriver to short the old connection. The new one still won’t turn on. My PSU is new, but I have another one available if you want to try it.

I’m wondering if others have faced similar problems—especially with CMOS battery failure or power switch issues. Is there a way to test the motherboard without turning it off completely? Could a reset button or another method help?
