Your remaining PC functions normally except for the USB ports, which remain inactive. The GPU fans are active, the GPU is spinning, and the cooler is operating. It seems the Ethernet light doesn’t respond when connected. I’ll provide more details to help resolve this as effectively as possible.
Check if there are any failure signs during the POST process. Does your motherboard display any debug lights? What is its specific model? Have you attempted to reset the CMOS?
I don't have access to that specific information. Could you provide more details or check the device documentation?
I question the PSU is not the problem, but it's an Apex gaming 750 Gold model.
The board seems to lack a debug LED, and it looks likely you're using a CPU without integrated graphics (probably not ending in "G"). CMOS stands for motherboard settings, which are saved on a memory chip that requires power constantly. That's why the board has a small battery. It might be that something went wrong with those settings, so you may need to reset it—like a full reboot. Unplug the system and either connect the CLRCMOS header at the bottom for 5-10 seconds or remove the CMOS battery for about 30 seconds. This clears the chip memory and resets the board. You won't lose data in Windows, but you'll need to re-enable XMP and reset any BIOS changes—settings you can access by pressing Del or F2 when the computer starts. The relevant header is the two-pin one beside the front panel audio header and next to CHA_FAN2.
Next steps might involve reinstalling the RAM and the graphics card—removing them and reinserting them. You can also test booting with only one RAM stick instead of both, assuming you have two. If that doesn’t resolve the issue, the power supply unit could be the problem. Have any events occurred that might have led to this? Or did you bring the computer in today without it working?
I observed that the CPU was running hot, so I removed the fan and applied new thermal paste. I took out the GPU, unplugged the RAM sticks, disconnected the CPU port from the motherboard, and also unplugged the fan. After reassembling everything, the system booted up. The GPU fans started spinning, the RAM lights up, the CPU fan spins, but the mouse and keyboard don’t work, and the monitor fails to display anything.
