However, I had 16GB of RAM, it only booted with 8GB RAM (the other piece didn&#39;t read). So I powered down, re-insert both RAMs (in case it got moved when installing proc). Tried to switch on but got met with a completely black screen.<br /><br />After around 1 minute, it resets, and re-boots to the black screen and this becomes a loop.<br /><br />What I tried to do to troubleshoot:<br /><br />1.) Remove RAM #2 and boot with only RAM #1 <br />2.) Remove RAM #1 and boot with only RAM #2 <br />3.) Remove graphics card to boot with Mobo HDMI <br />4.) Remove all Sata except OS HDD<br />5.) Reset BIOS and reboot<br />6.) Remove Mobo battery for 10 minutes before reboot<br />7.) Current Mobo BIOS version is updated, but updated to a Beta version (2.60)<br /><br />All the above didn&#39;t work. Put back in the 4460 and it booted.<br /><br />Sent 4790K back to shop, shop owner put it in his test mobo and it booted right away.<br /><br />Anyone got any clues on what I can do wrong as now I need to take back the 4790K.<br /> wolvngelz Technical Support Tue, 23 Apr 2019 16:40:29 +0800
