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?

it dose not have a second monitor
when it boots properly i can see the windows screen but when it dose not u can see nothing on it like the machine has started but the monitor is not switching on for sum reason.

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 This way we can see if it is a LCD Black light problem or possibly a outdated Graphics/BIOS driver.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nothing .i also tryed the flash light trick and could see no windows loading screen.i do not think the drivers are out of date because i use a program that updates them for me (name of the program :Advanced driver Updater)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 )

 

[ellellell1]

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.

ok so noting is connected besides the power
and when the menu pops up it says
repair youer computer
safe mode
safe mode with cmd
enable boot logging
enable low resolution video
last knowen good config
directory service restore mode
debugging mode
disable auto restart on system failure
disable driver signature enforcement
and boot normally witch should i select
i will update the bios online as i do not think that driver updater did update them

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

Good Job .

I can't think of any other reasons at the moment why it would still not boot unfortunately, but some other SF members might have some ideas .

I will also post any more ideas as I think of them to help too.

Edit: When you say it booted successfully 6 times in a row. Did you do a Power Button Shutdown (holding the power button for a force shutdown) or are you shutting it down normally (start menu > shutdown).

Sometimes doing a Power Button Shutdown each time you turn off your computer can damage the computer boot process.

i did a (start menu > shutdown). and (start menu > reset (although before when my bios where outdated i did have to manually power it off a few times )
