Can't get into BIOS

[ELicious]

I have an MSI P6N platinum 650i MB and a Logitech G15 KB. I could get into the BIOS just fine before by mashing the del key when I boot it up. I was doing it just earlier today. Now when I mash the delete key, nothing happens. I also can't choose the boot options with the arrow keys, or press enter to choose boot windows normally. I know it recognizes the KB because it says right at bootup, USB KB recognized, but none of the buttons work until I get into Windows. How did this happen all of a sudden and how can I fix it? The last thing I changed in the BIOS was upping the RAM voltage by .05V. Now I can't even get back into the BIOS to change it back. I've tried resetting and powering off the computer many times. I've even turned off the PSU for several minutes. Nothing I do will get me back into the BIOS.

clear the cmos, and reboot, see if you get the keyboard back. if not, the ps2 port for it's probably damaged, unless this is a cordless keyboard.

He said it was a usb kb, so I doubt it is a problem with the ps/2 port. A damaged port would not work in Windows either.

Did you change the "legacy usb support" section of the bios? If you did, an easy solution is to hook up a ps/2 kb and reset it.

I was hoping to avoid reseting the BIOS and my settings, but that's ultimately what I had to do. It came right back up with the KB working again. And no, I did not touch the legacy USB support stuff at all before or after. The last change, and only change I made was upping the RAM voltage by .05V before I lost all KB commands during boot up.

well, glad to hear it. I'd leave the voltage settings well enough alone, obviously that system rather run stable. glad you're able to use your pc. case closed.

I had the exact same problems with my G15 on my old Abit Fatal1ty mobo,I had to use my old keyboard to access BIOS commands and also whenever I reinstalled windows (Had to use the USB to PS2 adaptor for this as my USB seemed to be inactive til windows started up).

On my new Asus the G15 is detected during POST.
