    PS/2 Keyboard not working in Windows7 after BIOS update but works in linux

    taral

      Hi,

          My system specs: i5-2320

                 Motherboard:  Dh61WW

                RAM:  4 GB

       

      I recently updated my Bios from 0048 to 0099. After update my pc dint start (many users had problem of boot failure after update to 0099). So then i updated it to 0109. Pc now works but since then my PS/2 Keyboard is not working partially.Tried updating to 0111 and 0113(latest at present) but still problem is same

       

      When I start Pc, I can enter Bios menu by pressing the key, but once Bios opens, I cannot use my keyboard (surprisingly, usb mouse works in bios,vich, before update dint used to work.). Same with boot sequence menu,i can enter but cannot select nething as keyboard stops working. If I dont enter Bios or boot menu, I come to a screen where i ve to select the os vich i want to start (I ve windows 7 and ubuntu dual boot options) I can use keyboard to select an option i.e keyboard works at this point. If i go to ubuntu, keyboard works perfectly fine. But if i select windows 7, Keyboard stops working. In device manager, the keyboard option isnt seen only..

       

      if i update Bios, Keyboard will work when it restarts 1st time after bios update, but if I shut down or restart again, It wont work. So,if i want to use a keyboard, I ve to update bios everytime i start pc( doesnt matter even if i install same version of bios).

       

      Also, I tried resetting bios configuration via battery removal, jumper reset method but dint help. Installing windows 7 or windows 8 doesnt work.I already tried it.

       

      Jus after I updated bios,keyboard was detected in bios (pic attached)

      But after I restarted pc, Keyboard is not detected (pic).. As u can c, der is no Keyboard detected in device manager.

      Sometimes I get such msg (pic) but if i select "restart now", again same problem occurs.
