I've just started having an issue where my PC won't boot when I have the BIOS switch in position 1. It gets stuck in a loop where the LED display cycles through codes 15, 36 & 32 and just repeats through those codes over and over. If I switch to BIOS 2 it will boot up fine. I haven't flashed the BIOS recently (most recent version was flashed to BIOS 1 about a month ago, 2 is still on what the board shipped with) Any suggestions as to what could be causing it? I've tried clearing the CMOS and that will get me in to BIOS so I can load optimal settings and system then boots but on restart it goes back to the cycle.
