Most of the time when you flash the bios, you need to transfer them to a 3.5 floppy disk. Then stick the disk in the A drive, shut it down and restart. When it reboots, it will go into DOS momentarily and flash the bios. It should then reboot, at which time you need to remove the disk. It should then restart in the normal mode. Even though EVGA has a program built into the motherboard utilities to download and flash in Windows mode, sometimes the bios just won't flash correctly OR the bios just won't catch. I had an EVGA 590 SLI and had the same problem. The program just wouldn't work directly from the internet or by saving the file in Windows. I had to transfer to a disk and flash the bios as above. One of the best utilities for flashing the bios in Windows has to be ASUS. Since I upgraded my board, I've upgraded the bios 2 revisions and haven't had a problem as of yet. ASUS rocks!!
