When i turn my computer on the screen is black for awile then it comes on where i can see my screen saver why does it do this


Turn the computer off.
Turn the computer on,
and keep pressing the 'F8' key until you see a "start-up" menu.
Choose "Start in Safe Mode".
Does the screen now look normal?
If so, set the "screen-resolution" to 800-by-600.
Then shutdown and restart.

COMPUTER IS FROZEN..ERROR MESSAGE SAYS CHECK SIGNAL


So the message you get on your screen is telling you that there is no signal coming from the computer, Screen and computer are different parts, the screen is not your computer.

So this means that your computer is either not connected to your screen or not turned on. if it is turned on and properly connected, you have a hardware problem, take or have someone come over to inspect the pc in person.

My pc is showing a white screen when iys on


Is it an LCD monitor ?
When an LCD screen has turned completely white, there are three normal causes: the screen is defective, the video cable is not connected correctly, or the graphics card on the motherboard of the computer is faulty. You will need to troubleshoot these possibilities to determine which problem you have. If you are not experienced in working on computer equipment, you should not attempt to disassemble your LCD screen because you could easily damage it. Seek professional assistance unless you have experience working on computer hardware.

Disconnect the white LCD screen from the computer by unscrewing the blue monitor cable. Connect the working LCD screen to your computer by attaching its blue monitor cable to the same slot. If your computer display does not show on the functioning LCD screen, try rebooting your computer. If it still does not display, the problem is with your computer's graphic card on the motherboard. Seek professional repair assistance. If your computer display shows normally on the working LCD screen, proceed to Step 2. Unplug the LCD monitor with the white screen. Disassemble the rear panel of the monitor with the small screwdriver. Carefully separate the screws into piles so that you can keep track of how to reassemble the monitor. Locate the internal video cable, a gray cable with a plug on the end that connects to the main components of the screen. See Below for the References section for photos of the video cable for assistance. http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/ Unplug the cable, checking for any debris or blockage. Reconnect the cable firmly. Reassemble the LCD screen. Plug it in and connect it to your computer. If the screen is still white, you have a defective LCD screen. You will need to replace it or take it to a professional repair service for assistance. Hope this helps.

Hp pavilion dv7-4165dx black screen


A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,


if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on.


To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.


Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard.


Press the power button if the screen remains black.

Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue.


Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue.


Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.


Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.


Slide the battery latch to eject the battery. Pull the battery out of its compartment.


Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard.


Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.


Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector.

Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place.


Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective.

If the external monitor works, the LCD screen could be broken.

If the monitor doesn't work, the motherboard or video card might need to be replaced.


Hope this helps

gateway zx4300 black screen fix

i think i might have found a fix, if you know how to fix the xbox with the fan trick this one will sound close to the same.

if when you turn the computer an you get nothing not one bit of color or brightness from the screen this is your fix, well it worked for me.

i am not responsible for any more damage you might encounter, this does require disassembly


1. take the computer apart until you have the fan and heat sink in front of you.


2. remove fan and heat sink from mother board.


3. (at own risk) with computer open an heat sink off plug in the power cord and turn the computer on.


4. leave computer on for 8 to 10 mins.


5. turn computer off after 10 mins remove power cord and re install heat sink and fan.


6. hold pwr button down for 15 sec.


7. plug computer back in and you should now have your screen back.


this method worked for me i am using the computer with the bad screen to type this up an has been restarted a couple times an is still working fine! hope this works for you!!
