Ivanca Hi there, it might be the power supply issue.
Please send us a picture of the SN on the bottom of the PC.
Please turn off the PC , unplug the power supply and other USB devices, then put the pin in the CMOS pinhole and press it for about 10 seconds , restart the PC after ten minutes.
Here is the tutorial https://url.bee-link.cn/5FdW
