I updated the BIOS on a new MSI H97m-G43 mobo using the recommended procedure (`download latest BIOS file' `place on USB disk' `use M-Flash' -- page 3-7 of manual). The mobo no longer powers on (the best I get is some spinning of the CPU and case fans). I jumped the CMOS to reset, but still no luck. I've removed the gpu, RAM, and drives, too. RMA time? If so, should I contact amazon or MSI first? Thanks!
