keyboard mouse stopped working after improper shutdown

[gurupreet31]

Hi,

the issue i am facing--- yesterday my laptop got shutdown because of power loss after that

-      on booting win 7 i got a BSoD bad_system_config error three times then
-      On my fourth attempt the win7 os started to boot again but the keyboard and mouse were not working (both external usb and internal).

My system details--------

asus k53sv laptop with

1.  i5 processor  2. 8gb ddr2 ram(2sticks of 4gb)     3. geforce gt540 graphics card  4. 750gb seagate hdd(with 4 partitions(199gb*2 ,288gb*1,10gb*1)

5.  3usb ports(1*usb 3.0  , 2*usb2.0)

 I have a dual boot config so Both 199gb partitions have os namely winxp pro and win 7 pro.

WHAT I HAVE TRIED

1. Safe mode does not work i.e keyboard mouse do not work(both usb external and internal do not work)

2.win 7 repair found no errors

3.Do not have a Restore point so could not restore it to previous working condition.

4.Tried to shut down laptop remove battery and power and press power button for 20 -25 second release the button then put everything back again..

5.Done online spyware bot scan,Malwarebytes scan, avast free scan.(from win xp)

OBSERVATIONS

1.keyboard mouse work completely fine in BIOS and in win xp.

2.The keyboard light goes off as soon as the win 7 welcome screen is shown.

3.Initially in the second try win 7 os was detecting external keyboard showed installing devices notification but then did nothing.

NOW  external usb keyboard and mouse are not detected at all in any of the three usb ports.

what i am trying

1. Find the win 7 startup folder from win xp and add teamviewer shortcut so i can remotely control the PC and remove all keyboard and mouse drivers.

2  There is a BCDEDIT method in win 7 repair regarding BSOD bad config error checking up more on that.

ANY SUGGESTION IS WELCOME AND I WILL BE ONLINE ALL DAY IF U WANT ANY OTHER DETAIL JUST ASK ALSO.I WANT TO TRY EVERYTHING BEFORE FORMATTING.

THANKS IN ADVANCE
NOTE-right now win 7 boots up fine only issue keyboard and mouse not working in both normal mode or safe mode.

Have you re-installed the ASUS keyboard/pad drivers ? ?

[gurupreet31]

how can i do that without any input device available within the windows environment?

[patio]

Try it in safemode...
Try an External mouse...

Barring that the Tab + arrow keys can navigate enuff to install a driver...i've done it many times.

hi patio thanks for the info but as i mentioned in my post in the 3rd line and the last line. The keyboard and mouse(both internal and usb external) are not working in both safe mode and normal mode.So doing anything from within windows is impossible without any input device whatsoever.

thanks

External mouse and keyboard then...
There are settings on laptops that disable both...have you checked thats not engaged ? ?

It'll be in the Manual...or at the laptop manuf. site.

yeah someone else in another forum pointed the same thing out so i checked i have a touchpad disable function that works only internal touchpad other than that there are no more input device disable functions available .SO we can rule that one out.
thanks

Can you get to a Restore point from the advanced boot menu ? ?

[gurupreet31]
