My Dell Vostro 1500 notebook on Windows Vista Business 32 Bit has been acting funny lately. The computer is a lil over 3 years old now and this weird thing where the laptop monitor randomly turns off, but computer is still running. Is there a driver thats corrupt that i need to reinstall, or is it a hardware issue? After the monitor goes out i close the lid to put it to sleep, then its perfectly fine after i open it up (login screen appears, etc). If i run the computer on its battery only, this problem never happens. Whenever its plugged in, it messes up. Please help!!
