WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove the memory modules from their slots. Take the opportunity to clean the slots on the motherboards and the memory module connectors. Use compressed air to blow dust away and clean contacts with a soft cloth. Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components. Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r Allow the pins to dry. They will air dry in a matter of minutes. If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer. Check the memory module and memory slot contacts. They are either copper tin or gold. The colour will tell you which they are. Mixing tin and gold can result in corrosion that prevents proper contact. Look for any sign of physical damage to the memory module, memory slots or the motherboard. Reseat the memory modules. You should hear an audible click when they are in place. Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard. The hardware that you are trying to access is damaged or failing.
The device drivers for the hardware are faulty or incompatible.
There is a connection problem such as a bad cable for internal hard drives
Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty if its a flat 40pin ide this will be the first to fail Make sure all leads that are attached to your drives dvd\cd and floppy (If Applicable) have secure connections and are not faulty. or just replace them they could be faulty a computer needs power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error
Hope this helps.

BIOS is fixed program that starts up the computer. BIOS is initialized during start up of HP Compaq-6715B which sets the computer settings to be uploaded. BIOS enables the creation of a bootable diskette, CD, or USB key that can be used to locally restore or upgrade the System BIOS in the supported notebook models with a 68YTT Family ROM. Only insert the USB drive that will be used to format and create bootable BIOS upgraded USB media. However, you should remove all unused USB drives and flash drives from the notebook before. In order to ROM family and ROM date, press F10 on the target notebook during startup to run the setup utility.
The tips to get into the BIOS of HP Compaq-6715b are:
BIOS often has a blue background, and uses the arrow keys, PageUp, PageDown and enter keys to change the settings. After you have got into or accessed the BIOS, you can change the boot order settings so that the floppy disk is checked first to see if it contains a bootable program. Usually a message will appear telling you how to enter the BIOS setup program as the computer starts up, such as Press F2 for Setup.
Your HP Compaq-6715b might be configured to show your computer's logo instead of important BIOS messages. In this case, you can press Esc or Tab while the logo screen is visible. If you are facing problems pressing the pause button in time, turn on your computer with your keyboard unplugged. In this situation you will receive a keyboard error, which helps you in pausing the startup process long enough for you to see the keys necessary to enter BIOS.
Independent of OS
The PCs with both PS/2 and USB connections are configured to only allow USB input after the POST. If you are using a USB keyboard, it could be impossible to access BIOS. You would need to connect an older PS/2 keyboard to your PC to access BIOS. The BIOS accessing is independent of any Operating System on your computer because the BIOS is part of your motherboard hardware.
