BIg OreganoHi Sajin, thanks for the help. The beeping does not line up with any of those codes. It is repeating and doesn't stop. Plus, it seems like more than a coincidence that the beeping and the light are happening at the exact same time. The beep is very faint and I can only hear it when I put my ear close to the PSU. Is there any possible way that the PSU could be making that beep? And is the "E" even supposed to flash?
