Toshiba C855D Keyboard not working

[michaelal3]

I have a Toshiba C855D laptop that I am trying to reinstall Windows 7 from a CD on because I recently got I a CBT Blocker encrypt virus on it. All my files are backed up so I'm just trying to reinstall Windows 7 on it to start from scratch but I have a very peculiar problem. When I start up the computer my keyboard does not work so that I cannot even put in my password. But by experimenting I discovered something: I have a USB mouse hooked up to it and with the mouse I put the computer on hybernate and when I take it out of hybernate then the keyboard works fine (quick note here: when the keyboard is working the light on the "number lock" key is on and when the keyboard is not working the light is off). So here is my problem: when I restart the computer to reboot it from disc (by pressing F12 key) the menu comes up for me to reinstall Windows 7 but I cannot navigate the menu because the keyboard does not work (the light I mentioned before turns off on restart) and the USB mouse does not work either because apparently it is disabled for a Windows 7 reinstall from disk. Is it that I need a new keyboard but if so then why does it work fine when I bring it back from hybernate? Can someone please help me with this?

The quick solution might be a usb keyboard. otherwise...

When you initially boot up you should get a bios screen that says press F2 for setup. Do so, for two reasons: to find out if the kb is working in DOS mode, and then when you are in the bios go to the options tab and select ~load default options~. then Accept changes and let it reboot.

The usb mouse should have been working in WinRE.

If I understand you correctly you are trying to do a Clean Install using a Windows 7 DVD.

Here is a tutorial by Brink that will show you how.

I would suggest reading completely through and understand the tutorial before starting the Clean Install.
