| Hello guys, I have a problem that is driving me crazy.I turned on the computer and everything worked fine, after a while, when I again sat at the computer keyboard and mouse did not respond. After restart it show CMOS checksum error – Default loaded.Windows offered me repair and start normal options, however, as the keyboard is not responding i couldn’t choose any of these. I found an old mouse that has a USB hub, through hub I was able to connect the keyboard and get into the bios. I will write what I can do and what can’t:I can get into the BIOS if the USB keyboard is connected via hub. (Sometimes) I can not get into the BIOS if the USB keyboard directly connected. I can load the OS, but the keyboard does not work through a hub, nor directly. Steel-Series Mouse does not work in the OS, but this old mouse(with hub) works. (after a few reboots). USB provides power, i can charge phone. USB does not recognize the new devices in the Device Manager. Bios detect USB storage, but can not boot from USB. I updated the BIOS, CMOS flash – few times, changed the battery, tried without hard drive, switching memory, still the same – USB not responding. I’ll buy another MB tomorrow, because it’s urgently.

BIOS Checksum Error, Usb Not Responding.

Flashing the BIOS multiple times isn’t going to help, once it’s done, it’s done. You should be running version F14.
Unplug the power cord, then reset the BIOS using the clear CMOS jumper – move the jumper to the clear position, wait a few seconds, then move it back again. Reconnect the power cord, power up & immediately enter the BIOS. Correct the date/time & run thru ALL the settings, adjusting as necessary. Save & exit. Do not simply load BIOS defaults & expect everything to work properly.
