USB devices stop working on Windows startup

[geno2k3]

When i start the computer i see that the USB devices are receiving power. As soon as the windows logo / loading screen pops up the USB devices die. I get to the user login screen but i cannot do anything because my computer only has usb ports for my mouse/keyboard.

I do not want to reformat my hard drive due to having many family pictures stored on the computer.

What went wrong?

How can i fix it?

Thanks

This could have been caused by a malware infection, driver update or a resent errant Windows Update. Try using a PS2 keyboard and mouse to troubleshoot the possible causes
