HI, there

Please make sure you do CLR CMOS in the right way with all cables unplugged.
First, please unplug the power supply and HDMI cable.  
Secondly, Please hit the "CLR CMOS" button for about 10 seconds.
Ten minutes later, plug the power supply and HDMI cable, turn on the PC again,  
once turn on the PC,  you will need more than one minute to wait for the PC to enter the system.
See if it works.  Please try few more times.

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://mega.nz/file/XqZX0TIR#_D ... hBpQ959cg5U3Yw4u1Cc or  [https://mega.nz/file/7nwDmCaL#Uy ... P9gt2Br3xyCG1SCdbrA](https://mega.nz/file/7nwDmCaL#Uy ... P9gt2Br3xyCG1SCdbrA)
