Hi! So I just finished building my first gaming pc. I noticed that after turning on the power button the Aorus Logo will appear on the screen and the Red lights on the lower right angle of the motherboard will start to lit. First the DRAM followed by the CPU, VGA and BOOT. After a few seconds the loading process will continue but then it will suddenly stop leaving a blank screen on the monitor (No Signal) with the VGA LED lit on the motherboard. I tried to configure everything in the Bios, like putting the Storage Boot Option Control on UEFI only. Tried the Fast Boot as well, changing booting options but still the VGA LED remains on. I have to add that after making or not changes in the Bios, by clicking Save and Exit Setup or Exit without saving, the computer will restart and will boot up normally directly to the Windows 10 desktop and will work normally fine even if you shut it down again and turn it on immediately. I've tried already as well to unplug the RAM, all the wirings from the 24 pin connectors, CPU power connector and pcie power connector and still nothing changes. The only problem is that it won't boot up after 30-several hours after shutting down or putting it on sleep and will have to access first the Bios then or either click save and exit or exit without saving. I wonder if guys have any suggestions regarding this problem of mine! Thank you in advance!
