After updating bios blank screen

Before I go any further, I should tell you that you should not go into the BIOS unless you either know what you're doing or you're working on a computer that is unimportant to you or anyone who may need it.While it's relatively difficult to destroy data by changing values in the BIOS, it IS easy to make changes that would prevent the computer from booting.Before the computer can access the main OS, it's going to need a little help.The basic instructions that a computer uses to get up and running are contained in the BIOS (basic input/output system). The black screen is happening after the logo appears so I know it's not the display that is broken. I've only tried taking the battery out and powering off. Actually, this could have been much easier done with the help of Malware Bytes (trial version). Disconnect power (cord and battery if laptop) after login 2. Restart the computer - helped me ive just had same problem screen goes blank on boot ,, installed new hd new win7,plugged into hdmi VGA work fine but no notebook monitor ..i will see bios boot and thats it when windows trys to boot goes blank just black screen , ive tried every way but loose ,, and came across this post ,, changing power options in control panel worked like a treat ,, ive rebooted the laptop several times from shutdown and restart and both work.I plugged it in to my external monitor and everything works fine too, so probably not the HD? I went into F2, but I don't know what to do while there. Start the computer, it should present several start up options on the black screen 3. connect to external hdmi or vga change power settings or go into safe mode by pressing F8 before windows boot and change settings , This only worked for me with different monitor ,, it worked for me ...This video tutorial shows you how to fix the “black screen of death” problem of the Acer Aspire One netbook.

So they have reduced the power of these fans that are used to cool the hardware. After a pause of 15 - 30 minutes, restart the monitor and then the computer. If it was a problem of overheating, the computer screen should now show the system booting normally. If you have just installed the computer and nothing seems to work, it could a bad monitor or a low power supply. Check if the monitor light is green, orange, yellow or red. Save important financial/tax information on CDs etc. Store copies of your favorite music on CDs or export them into other media. Install Recovery console so that it may be used when computer crashes! Make sure that your computer has updated anti-virus software and spyware.

The information in the BIOS allows the computer to interface with the monitor, keyboard and mouse (among other things) until the OS can take over.

The BIOS is stored on a small IC that has a small amount of flash memory.

As I mentioned earlier, the computer without software (or firmware) is essentially useless.

For most of our day to day use, the main operating system (Windows, Linux...) determines the capabilities of a computer.
