Last time I installed a Gigabyte board I had to use PS2 keyboard since a USB one did not work until I enabled the controller in BIOS. I did not try all the USB connectors some might be native, try swapping the keyboard around if USB.
Sorry, I forgot to mention that. Yes, my PS/2 keyboard was the first one I tried. The keyboard's lights were lit (Num/Caps/Scroll Locks) but I couldn't get into the BIOS or anything else.
I then tried my brand new out of the box USB keyboard. Same thing - lights but no navigation. I further tried my old stand-by USB and still nothing.
I doubt I'm the only one who's ever had this issue, so I'm hoping there's a solution besides RMA. Is there a way to bypass the BIOS setup and still be able to boot from Windows disc or some other way to start this process?
Yikes! I ran into a similar problem with you when I was messing around with my BIOS after my system was built. I disabled my USB controllers to get Windows 7 to install correctly, and I forgot that I would need my keyboard and mouse (both USB). After some hair pulling, swearing, and ground-pounding, I finally remembered that my old computer has a PS/2 keyboard. I simply plugged it in and was able to use that.
As for your care... both PS/2 AND USB doesn't work? Very peculiar, as most BIOS just has an option to disabled USB and not PS/2..
Well, after several attempts to resolve this issue with suggestions PMd to me (thanks guys - great to know there's help when needed), I've decided to pursue Newegg RMA as I believe I have a bad PS2 port.
My new issue is that I'm now rethinking Gigabyte vs Asus. I hate to admit it but I may not be as forgiving as I thought!
How did you solve it? I exactly have the same problem. PC is stuck on logoscreen and does not respond. It seems there is nothing to do. I don't even know what causes the problem. Any ideas? Motherboard, memory or processor maybe?
