What can this be??

Good day all,
Just wanted some more help, I know it can be a pain, but please help, I have a satellite Toshiba lap top, yesterday was working fine, all of a suden the key borad is not working, I did check the the device manager and I have 3 (!) marks besides the DVD driver, mouse and in error I deleted the key board, how can I get this back? the key board also had the exclamation mark and in error I deleted it.

 

Un-install them through Device Manager, then re-boot and see if Windows re-installs them.
If it's a no go, post the full model# of your laptop.

Use Everest to get a report of your system’s hardware, OS, and drivers. Upload the report as an attachment
Everest: http://www.majorgeeks.com/download.php?det=4181

When Everest is done scanning, click "Report" at the top of the Everest window, click next to get to "Report Profile", select "Hardware-related Pages", click next, select "Plain Text", click "Finish". Then when it is done processing, click "Save To File". Save it where you want to. (I would use Desktop.)
Click "Go Advanced" in the MG reply box, scroll down a little way until you see "Manage Attachments", click it, browse to your file, click "Upload", and close the window. Then submit the post. You may have to also type something in the reply box, like, "Here's my report.", so that it will submit.

 

It is fixed now, by accident!!!!! LOL
I went to my device manager and deleted the keyboard, next time I restart my computer it automatically located the drivers for me and we are back in business.!!!!
