IsacV2,
Go into the bios main page where it shows the bios information and firmware versions and check if there is any firmware that doesn't show the version or shows N/A
Some bios versions that update other firmware require both bios files to be updated or when you change from one bios to the other it will go through the update process
Why it is doing this when changing erp I do not know unless you have a corrupted bios, I had to purchase a couple new bios chips once because both were corrupted, for MEI version showed N/A is why I ask to check, sometimes flashing the bios using the Flashback method can correct the bios sometimes not
I don't think it is your power supply, what kind of adapter are you using? The same lights bother me also, especially mouse and keyboard
