Why does my HP laptop give a sound before start time?
Please give me solution.
Hello, what kind of sound are we talking about? It is possible for the dvd/cd drive and your harddrive to make noises when starting up. Also, fan/fans make noise as soon as you press the power button. Some noises are normal and some of them are just telling you that your harddrive is on the way out, or something wrong with it.
Does the sound come after you log in, or right after powering up?
Some BIOS's (Basic Input Output System) make a beep (as mine does) to indicate what status it is. Three beeps for me means that it requires a password (the bios password), etc.
Driver problem, you have to uninstall each one and reainstall, start with audio device. Open the device manager then right click on your audio device and choose uninstall then reboot and let windows install a new driver
