More thanlikely just your keyboard is going bad. The pads under the keys will wear out over time and not make contact correctly with the electrical pad underneath. The keyboard on a laptop acts like a big electrical circuit and these wear out over time and use. Change out your keyboard. Send me a message with the make and model and I'll post a link to the factory service manual on how to dissassemble and replace parts.
1. In case you want to perform a clean install (format hard drive and install a new windows...note that you will lose data so i suggest doing a back-up first), connect your usb drive to your laptop and put in your cd installer. Restart your laptop. When you see the dell logo, press F12 then release. (you have to really watch for it as the alloted time to do so is very small as you may have already noticed.) keep doing the press and release on the F12 key until a boot menu appears. Use your arrow keys to select the boot device to boot from (in this case, your external dvd drive)...
2. If that does not work, restart your laptop then go to the setup by pressing F2 when you see the dell logo (again, you really have to watch for it). when you are in, use arrow key to navigate to "system". press enter to expand the selection. Then use the arrow key again and select boot sequence. press enter. on the right side of the window, you will see the list / boot sequence. use arrow key to select usb external storage device. Then press U to move it to number one (see bottom screen for menu on navigation). When it is on number one, press enter. This will take you back to main menu. Press Esc key then choose save and exit. Your Laptop will then restart on your usb drive...watch for the "press any key to boot from cd..." then follow the instruction on windows 7 installation. Hope that helps...
