sony vaio vgc-rb40 mouse and keyboard dead after updates last week

I am working on a sony vaio vgc-rb40 in which the mouse and keyboard don't work. I have tried the ps2 ports and the usb in both legacy and 2.0 the computer sees the new device and installs it in usb but it still does not work. no keyboard or mouse in safe mode but it does work in the bios and both the keyboard and mouse worked when in desperation a ran a bit defender rescue cd just to see if by chance is was malware. The computer other wise boots and seems to run perfectly it just has no input devices what so ever. The one strange thing it does is 2 quick beeps at post but I cant figure out if that is normal for a vaio or not, all the codes I see for a vaio are multiples of 3 beeps so I think it is just the post beep but I am not sure. Thank you for any help
