Hi Guys
 
I have just did a bios upgrade to version 77 on my E760, loaded bios defaults before, did the upgrade, reset cmos.
 
Now on post screen after detecting the drives it hangs and says :
 
CMOS checksum error - Defaults loaded
 
Press F1 to continue or DEL to enter bios.
 
at this point the board gives me a F7 error code, I can't press F1 or DEL, as my keyboard (logitech G15) isn't working, strange is that when i plug a memory stick into the keyboards hub I see the status led on the stick flickering, so I assume the KB is powered..
 
Anyone got this problem too ? What for options do I have ?
 
Have removed all drives, reseated ram, cpu, gpu. doesn't matter what I do, I get this annoying error.
 
I haven't tried a PS2 Keyboard yet as I don't have one, or an adaptor for the usb KB.
 
Any help would be great.

got the same problem you do man, same board, same keayboard... although i got code 7F  also checked with a P/S 2 keyboard and nothing!!  the lights flicker once and thats it! after that nada, p/s 2 , and usb don't work can't get into bios... any luck on yours yet?

Hmmm, i actually noticed the same issue. WEll, till i switched to an Eclipse anyway. It might be because of the leds or something simple. What i did was switch the usb port it was in and press del like there was no tomorrow. Worked about half the time, i just decided to plug in an old one after being frustrated and had no issues.

Well, did you try any other USB keyboard? Like others have said, the logitech keyboard has had issued with this. Before going to the extreme of a new motherboard, try a cheap usb keyboard ("borrow" one from a friend, or frys)

buy a asus board if you want and next week i will see you over there maken the same post becouse the g15 and g19 for some off the wall reson dont detect on most mainboard bios. buy a 5.00 keyboard and move on

okay, borrowed 4 USB Keyboards. Rosewill,Dell,Logitech,and microsoft. and none of them light up or register whats soever. P/S 2 didnt need to get cause i got 6 of them... tested all of them and nothing. except that with the P/S 2 keyboard when i turn the motherboard on, it lights up once for less then a second, then a second time when get into the CMOS checksum error screen. and no matter how many times i spam DEL, and F1 it just doesn't work. Also swapped CPUs A D0 with a C0 and nothing. Replaced the bios battery and nothing, replaced all the sata cables and nothing, swapped 4 hard drives, and nothing, tested with 3 PSUs and nothing, tested with 1 gig memory sticks, Corsair, G.skill, OCZ,and Kingston and nothing, tested on every dim slot nothing.disconnected all other hardware execpt kb and nothing. perhaps maybe i can still salvage this beautiful mother board one day, i'm not giving up yet. other then that man.. thank you for your advice.

Couldn't you contact EVGA and request a new bios chip or RMA the board?

 
bought it second hand a year ago, and didn't save the guys name or anything and to make room in my private messages i must of deleted hes info... so i have no idea who i got it from basically... 

Did this for someone over the weekend and the Logitech G15 keyboard works fine. Only thing I could say with this is that it's probably not the BIOS.

Have U been solved this? same problem here:(
