USB keyboard not working AFTER boot
Hello guys,
today my keyboard (hama wireless keyboard 2,4 G) stopped working after i changed my PSU. I hope i didn't fry anything but i doubt it because:
* the keyboard is working during boot (e.g. i can access the bios (and yes, everything is enabled there) and i can select the os in bootloader)
* when booting into ubuntu (on the same machine) the keyboard is working fine
* all other usb devices (usb mouse, external harddrive, usb sticks) are working.
During boot (black screen with win logo) the NUMPAD led is glowing (and responding) up to about one second before the login screen. Then the led goes off and the keyboard is dead.
I also tried another usb keyboard and different usb ports without success (unfortunately i don't have a ps2 keyboard around anymore so i couldn't try one of these).
I tried booting in safe mode, keyboard aren't working there either.
System specs:
OS: Windows 7 64bit / Ubuntu 9.10 64bit (dualboot via Wubi)
Mainboard: Asus M2N-SLI Deluxe SocketAM2
CPU: AMD Athlon64 X2 5000+
RAM: 4x Kingston 1024MB DDR2 800Mhz
GPU: MSI Geforce GX 260 896MB
HDD: 2x Seagate HD SATAII 300GB (RAID0)
PSU: Be Quiet BQT S6-SYS-UA-450W (before: Fortron ATX 350W)
Let me know if you need any additional info!
I hope you guys have an idea because i am completely lost
