Who is the computer manafacturer and the model? (example, HP Pavilion
dv6-1128TX)
What hardware has been installed recently if any?
Did you make any changes or 'tweaks' to your settings recently?
How old is the computer?
Are there any unusual beep codes?
Any errors (HDD/Memory specifically) ?
Have you flashed the B.I.O.S recently?
This information would be extremely helpful.
Here are just some things I would try:
Turn on the computer. When you see the computer manufacturers logo or text
saying "Press XXXX to enter setup" (replace XXXX with key name) , press that
key to go there. Now you'll have to look for an option to 'load fail safe
defaults' or 'load setup defaults'. Select this and press enter. Exit.
WARNING: Do NOT, I repeat NOT, change anything unless you are absolutely
100% sure that you know what you are doing. The BIOS controls the hardware in
the computer such as the video, sound, hard drive, memory, USB, and so on.
Good luck.
