1. Turn off the switch of PSU (or pull off the power cord from PSU), then clear CMOS. Leave the system for ten minutes. Then turn on the switch of PSU and power on the system. See if it works.Originally posted by: sun4384
Does the BIOS recovery feature work with a USB keyboard and a USB floppy drive? It looks my MB does not respond totally... (no sound or beep, just nothing on the screen). I suspect I might pressed the reset switch when the power is on... What happens in that case?
2. Do you mean that you tried BIOS recovery feature with USB floppy drive but it did not work? Unless boot block is not dead, it should work, and I don't think clearing CMOS killed boot block.
3. If none of them works, then RMA'ing the motherboard may be the last resort.
