Hardware and Installation problems can cause a lot of Crashes. When a piece of your hardware doesn't get installed or updated correctly and fails other pieces fail, too, leading to a major crash.
To Fix Hardware problems go to the Device Manager and look to see if there are any devices with a tiny yellow Exclamation Point Warning. This tells you what devices are having problem. You should be able to click it and find update driver, or you can go to your Manufacturer's Website to find all the updates to their drivers.
