Suddenly the "backspace," "g" and "h" keys stopped working. Due to this issue, I can't log in to use my computer.
I have a Pavilion g7-1260 us Notebook PC, Windows 7.
Please help becasue I can't use my laptop at all.

Well, to get logged in (assuming your PC is at least booting up to the Windows Logon screen), you can try to use the On-Screen Keyboard, just click on the Ease of Access button (should be on the lower left hand side of the logon screen) and put a check mark in the box next to "Type without the keyboard" and select OK. This should bring up the On-Screen Keyboard and allow you to enter your user name and password. Note that I'm assuming here that you couldn't get logged on because either your user name or password or both uses one of the keys that isn't working.
Alternatively you can also just connect an external USB keyboard, like what you might use with a Desktop PC.
That should at least allow you to use your computer somewhat.
To test your keyboard, reboot the computer and press F2 to access the UEFI diagnostics. You can find the full procudure in this document:
If you don't have the lastest UEFI diagnostics installed on your PC, you can get the download here for your model PC:
There is a keyboard test under system tests, it may take a while to get through the test procedure, but it will verify if the keyboard hardware is functional or not.
If the keyboard test all pass, but you still have problems with some keys on the keyboard, check that the keyboard language has not been changed. Go to Start --> Control Panel, choose "Change Keyboards or other input methods", then click the Change Keyboards button. Based on your model, you should have the English (United States) - US option selected. If some other keyboard is selected, that can cause some weirdness with your keyboard.
