First check the air cooling vents and make sure that the passages are not clogged with lint and other stuff.
Simply raising your laptop off of any flat surface will allow fresh, cool air to come in from the intake on the bottom of the laptop. This will solve many of the heat issues you might be having.
Also, let it be known that you should NEVER have your laptop on any type of soft surface, such as a pillow, blanket, thick carpet, etc.; Doing so will not allow ANY cool air to enter the fan intake, and could cause more system hang ups and permanent component damage. Keep it on a flat, hard surface at all times
Remove the battery and charger/ac adapter/power cord from your Dell Vostro 3300 notebook, press and hold the power button for 20 seconds to discharge any residual current inside the laptop. This clears your RAM and is like hardware reset. Replace the battery and charger/ac adapter/power cord and turn your Dell Vostro 3300 notebook on.
Boot in "safe mode". As it starts up press F8, the computer asks you if you'd like to start in safe mode. Highlight "safe mode" and press enter. See if your Dell Vostro 3300 notebook works normal.
If the problem persists, did you check if it could be your Dell Vostro 3300 notebook power cord or power source problem? Insufficient power might cause error messages that are misleading. Take the battery out and power on your notebook with the charger only. Make sure your notebook power jack and charger plug tip are securely connected. Did you notice the power jack loose?
