Hi again, ...is it post #5 that suggested a corrupted Bios? I think the reason my motherboard wouldn't boot was probably because the Bios was corrupted. A corrupted Bios may suggest the memory failure report seeing that Bios is saved in a chip on the motherboard. I have flashed a bios that did not complete so the bios update failed, and then, not because I knew what I was doing but because I just had a go I reflashed the Bios and it updated correctly. So you see, having incomplete bos information in the otherboard Bios chip didn't matter to the flashing program. For that reason, I suggest that the Bios is reflashible . The Bios is probably corrupted and flashing several times, and possibly but not necesarily with an alternative flashing program, like Uniflash, just might overide and replace a corrupted Bios. I am guessing, but if my motherboard failed on me again I would like to try this before I sold the motherboard.......again.
