Hello there,
if your machine cannot turn on,
Here are some potential solutions: First, Please turn off the PC , unplug the power supply, and press the CMOS button (if no CMOS button, please 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://mega.nz/file/XypwTISY#DV ... Z7f7qpKGP2E3nMHW8ms or  [https://url.bee-link.cn/5FdW](https://url.bee-link.cn/5FdW)  If the problem persists, please try other solutions:

①Please change another HDMI cable or power supply.

②Please take out the RAM ,please clean the contacts of the RAM with a rubber. Here is the tutorial  [https://url.bee-link.cn/AzzB](https://url.bee-link.cn/AzzB) or https://mega.nz/file/7nwDmCaL#Uy ... P9gt2Br3xyCG1SCdbrA

③ Please take out one RAM and leave the other one in it to test if the RAM is defective or not. When testing, please turn on the PC, and wait about one minute, if you can go to the system, Please repeatedly press delete key as soon as your restart the PC, go to BIOS. Go to Boot option, enable fast boot, press F4 to save.

④Please check if the fan spins?

⑤Please tell us if the Keyboard light is on ?(Very important). If the keyboard light is on, it should go to the system, we need to troubleshoot HDMI or the monitor.
