Hi PandaSniper100

This sounds like it could be a issue with a second monitor.

If you do have a second monitor plugged into your laptop when it boots up, Windows will most likely choose to display on the second monitor as its default display and will switch back/stay to its primary monitor (your laptop display or second screen depending on which screen you choose) when it has finished booting.

Can you see Windows booting up on your second screen?
Can you see Windows booting up on your laptop screen when you disconnect your second screen?

I also used to have this issue and solved it by going through the settings in the BIOS and changing the External Display to LCD Display Only under Boot Options.

It would also be helpful if you could tell us after it has finished booting, does the login screen appear?

Or does it simply not appear at all because the computer is on but there is nothing on both screens?

Hmm that's strange.

If you do have a spare second monitor, could you plug it into your laptop and see if Windows displays on this screen every time it has been booted? This way we can see if it is a LCD Black light problem or possibly a outdated Graphics/BIOS driver.

If you don't have a second monitor try this:

When the laptop turns on, but nothing is displayed. Use a flashlight and point it at your laptop screen. If you can slightly see Windows booting up but only very dimly then the Black light is broken, otherwise it might be something else.

ok so i did some testes with it and when its not displaying any images on the screen and i connect it to a separate screen it still displays nothing .i also tryed the flash light trick and could see no windows loading screen.i do not think the drivers are out of date because i use a program that updates them for me (name of the program :Advanced driver Updater)

could it possibly just be getting slow because i left it on last time i hit the power button and it took 10 mins before it booted up(i mean it took 10 mins to display the windows logo )

Okay, does the program update the BIOS driver too?

There is a possibility that it could be booting up slowly.

Do you have any USB devices or any other cables connected other than your power cord and internet?
If you do disconnect them and try to boot again.

Have you also tried to use the Startup Repair Tools?
This might be a bit tricky to get to at first with your booting problems but continue pressing F8 until the menu appears.

You should select repair your computer, then click on Start Up Repair.

Be very careful when upgrading the BIOS driver (if there is a new driver).
Make sure that the driver you have downloaded is definitely for your computer, its for the correct OS and it is the newest version.

i think updating the bios may have of worked i have booted it 6 times without it happening
lie leave this thread unsolved for like 2 or 3 more days to test it but t would usually not boot 6 times in a row
