Motherboard

An ASUS ROGSTRIX B450-F gaming motherboard that I have had been working perfectly fine for a year. Suddenly though, booting up the system resulted in the following message on the POST boot screen:

USB Device over current status detected !! System will shut down after 15 seconds

The system would shutdown and restarting would result in the same message. I couldn't get into the BIOS either as the del and F2 keys did nothing.

Do you have a USB keyboard? Does it work fine? Does it also work fine once you boot into your operating system? Does it not work at all during the boot process before loading your operating system?

If your answer is yes to all of the above, then you've very likely been an idiot like yours truly and enabled the Fast Boot feature in your Intel motherboard's BIOS without reading the fine print.

Earlier today, I found that one of my boxen had hung. I tried restarting it, but was met with a keening siren alarm from my motherboard. Giving it a rest and restarting was either producing the same siren or a hang after a few minutes along with some nifty monitor graffiti.

I had to clean everything inside my PC today due to heavy dust accumulation and in the process remove the processor fan to clean it and the heatsink below it. However, while I usually mark the "right side up" for the fan, I'd forgotten to do so this time. While it made sense to keep the AMD logo on top, I was still not confident to start the PC without being completely sure. Google spouted advice hither and thither, but the general consensus appeared to be as follows:

  • CPU fans should blow air into the heatsink.
  • Case fans should bring cool air into the cabinet.
