Preferred Solution: pc screen keeps turning off

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Here is the issue, when my computer goes to sleep after it's on for a while when I move the mouse to get the screen back up it shows the backround no icons or anything to click.
Same if I turn it off and turn it back on. I have to turn it off and on many times then go to safe mode and shut down then turn it on again for it to work. Just now I had to turn it on/off 4 times for it to show the icons and task bar. Usually it is left blank with nothing to click having no choice but to turn it off.
Norton says no viruses.
My computer is HP with windows 7. I bought it in 2011.
This problem has been happening for a long time. Please help.

A:When turning off computer & turning it back on again screen is blank

Hello squirrels and welcome to Seven Forums.

I think I'd start out by trying to do a startup repair. It's been suggested that the startup repair be done 3 times (regardless of what the notifications say) and the computer rebooted after each repair.

If this doesn't fix the problem one of the Forum experts has prepared these troubleshooting guides with some additional suggestions.

Hi everyone,

From last few weeks I'm having this strange and annoying blank screen of death. I could just see a blank screen (not a blue screen) while either waking up computer from sleep or while trying to turn on the display by moving cursor/typing something(waking up from power saver mode of display, I set display to be of after few minutes of inactivity). So essentially screen becomes total blank. Just once or twice I saw this BSOD "DRIVER POWER STATE FAILURE" but for all other times my screen is just blank. I could see the Hard Disk activity LED on during this blank screen. And almost after all subsequent boots, I could see "Windows has recovered from unexpected shutdown/serious error - Check for solution" message.

System - Windows 7 Pro x64 with all latest recommended and security updates

First I suspected its because of my nVidia GT525M GPU drivers (I was using official latest drivers 320.49), so I completely uninstalled them with regular uninstall + DriverSweeper 2.1.0 from Guru3D.com. I did not install any nVidia/display drives since then. But just now I got another blank screen after it. Also I started connecting my PC to an old Sony Bravia TV with HDMI cable and that time the automatic installation of drivers failed. That is my second point of possible problem. I've been using CCleaner to clean the unwanted registry entries and revo uninstaller for almost every unin... Read more

Dear all, Happy new year and all

I wonder if you could help...

My husbands laptop this evening will not turn on AT ALL. It was working perfectly well a few days ago:

When the power button is turned on all that happens is the power light turns green. There is no sound coming from the hard drive (the hard drive light doesn't even show). In addition, there doesn't seem to be a fan working. And finally, there is a light strange noise (not a hard drive noise).

I am wondering whether it is a motherboard issue????
Woud creating a recovery bios boot CD help? Would like wipe the hard drive?

The major problem is that the laptop is used for all our business transactions and GASP.... we haven't backed it up, so we could potentially lose very important data
Many thanks and I do hope somebody is out there to help us.

Much geekness

Hello everyone! Iv'e been having an issue that's driving me crazy and i'm hoping someone here can help.

The issue i'm having is when my computer goes into sleep/hibernate mode and i wake it up, the screen appears to have a resolution issue ( picture attached ). I figured this wasn't a big deal so i turned sleep/hibernate mode off and just turn my screen off when not in use. I'm getting the exact issue though! When i turn my screen off and back on, the resolution is messed up.
So now i need help resolving this. If it also fixes it for the sleep/hibernate mode, that would be great but not necessary
The ONLY recent change is I upgraded to an Asus GTX560 Ti DirectCU II Top OC graphics card. I installed the card into my computer and windows automatically downloaded the drivers for it.

Things i've tried:
1)Uninstalled and reinstalled graphics drivers using windows update and then again through Nvidia website
2) Currently using HDMI, but get the same issue with DVI-D (single) cord
3) Completely reinstalled Windows 10 Pro from scratch
4) Double checked all connections
5) Look through settings on my TV and settings on the graphics card through Nvidia Experience

You appear to have a very old Dell (OptiPlex?) model desktop.
What is its model name and model number?
What is the exact "service tag" and "express service code" numbers on it?

Is it running Windows 10 Pro 32-bit or 64-bit?
You should download and save the appropriate driver from the NVIDIA site, then select the custom install option, then select the clean install option.

Are you having the same issues when using a standard computer monitor instead of using a HD TV?

I had to do a clean wipe on a virus/malware infected HP All In One Touchsmart 310-1000z (2010 model). I have turned off hibernate, sleep, hybrid sleep, and hard drive sleep. Screen is set to dim at 3 minutes and screen saver at 10 minutes. But for some reason, the screen will just go blank randomly, it seems like maybe 45-60 minutes after being turned on.

Clicking the mouse does not bring the screen back, nor typing on keyboard, nor touching the screen. Have to press the power button and shut it off that way. The hard drive light does not flicker, leading me to believe it may still be going into a sleep mode I can't find?

Yesterday I was in a hurry and it was taking a long time to shut the laptop down. So I went for a force shut down. But now when I am turning on the laptop, nothing is happening. The screen is black, nothing is coming up. I thought it's a screen problem, but the buttons are also not working. I tried the Caps lock button, Mute button, Airplane mode button, but nothing is happening. The screen is black. And nothing is coming. I waited for 10-15 mins but nothing is happening. Restarted the device quite a number of times, removed the battery and then tried to turn it on. But at the end, the problem is still there. I need it today at 3 in the afternoon. If someone can help, it will be very kind.

Hello,I'm not sure if this is the right place to post but hopefully I can get some help or be forwarded to a place a I can.So a few years ago my parents purchased a C40-05 all-in-one desktop. From the start there were problems. It would hang at the Lenovo screen, continuously have to enter Windows Repair and would not shut down correctly. After updating via the latest updates from both Windows and Lenovo, the desktop's display seems to be not working. When I power on the screen just stays blank as if no power is going to it. However, if I put in a CD i can hear it spin and also I can see the power buttons on both the mouse and keyboard light up. I can't even access the bios as there is no display what so ever.  Any of you experienced this or know how I can fix it? At this point it's not really worth taking to a shop but if I could access the bios at least that would be a start. ThanksChris

Hi guys!I have a Toshiba Encore tablet with windows 8.1 on it. After an update yesterday, the screen doesn't turn off when it gets in sleep mode.It turn black, but it still has the background light on.The same update messed up the screen luminosity.It is set to maximum by default, and no matter how much I change it, nothing happens.The battery drains very fast with the screen on this way and I really don't know how to solve it.I tried system restore, but it didn't have any images saved, so I need a solution apart from that.Many thanks!

You could try rolling back the updates until you uninstall the "bad" one. Process of elimination is all I know if you cannot restore point your way out or apply a backup image.

My monitor turns off every now and again, I've changed the monitor to test if it was that which was causing the problem but it still happens. I've also changed the wire, checked the power supply (seems fine from what I can tell) and replaced the hard drive. I could be playing a game or doing nothing on it at all and it would happen.

Don't think it's the graphics card as when it does work the images are fine.

One thing I noticed when it does turn off is that my external hard drive turns off too but the computer remains on,also once when I was playing music when the screen went off the music stopped too. Makes me think its a hardware problem but not sure which.

I have no idea what I did wrong.

Took apart my laptop (see signature/system specs) to get the part number off the fan and put the computer back together as normal. Turned it on and voila, no display. Don't know why. Rechecked the connection of the display cable a few times, and still no display. I'm wondering if maybe I damaged the cable or the system board. The computer turns on though, just no display!
Took apart the lid to check the screen. Firstly, HP's construction continues to amaze me. These things are built like tanks for sure! Secondly, there's no visible damage to the screen or any components inside of the lid. Going to put it back together and test the screen one more time, and if that doesn't work, I'll test with an external monitor to see how things work out...

I know, vague, but I'm kinda stuck/lost here.

A:Screen not turning on

Hello kbronski,

Keep in mind that all the LCD wire connectors are extremely fragile. Do not apply too much force while reconnecting the cables. Secure the connector with the clear tape.

If the external monitor doesn't work, try power cycling:

shut down
unplug battery and charger
hold power button for 5 to 10 seconds to drain all residual power
plug battery and charger back in

If the external monitor does work, hold down the FN key while you tap the F-key with a picture of a monitor. Perhaps, it got turned off.

Hello everyone!
I have a big problem with my new Dell laptop - Inspiron N5110.
It was working fine at the beginning but now it is impossible to use. The screen of the computer keeps on turning off every few minutes...
I suspect it might be related with the fact that I started using HDMI cable when connecting it to the TV. The connection was working for a while (though it was possible to see the video on TV screen only, not on the laptop).
But now even disconnected laptop 'thinks' there is TV connected and automatically turns off the screen. The button on the far right side of the keyboard keeps on turning on by itself (square with a line across, indicating another screen used).
Please advise how to fix this major problem - it becomes impossible to use my new laptop...
Thank you in advance!
Best regards,

After leaving my Toshiba Satellite running on my bed on a particularly hot day last summer, the screen won't boot up when I turn it on. The screen remains off while the power lights, fan, drive, all seem to power on and run.

I have tried rebooting it by removing the battery and then turning it on again but it still doesn't work. I'm really looking for someone who can guide me through some troubleshooting so I can figure out what's wrong.

*edit* I forgot to mention I have also tried plugging in other screens and it does not boot up on them either.

Hi all,
Having a little problem here. I have a 7 year old Compaq Presario Desktop. 3 times now (Thurs night, Fri night, Sat morning) while it's being used the screen goes black, and the fans shut off inside the tower. But the green power light stays on. I turned off the PC last night to let it cool down but this AM the same thing happened again.

Is this problem due to the computer over heating? I just cleaned the whole thing up 2 months ago for the first time in a long time, but maybe something got in there causing the fan not to spin correctly.

Just installed 7100 and was setting up. I have a Toshiba HDTV on DVI (display numbered 1) and an Acer lcd on VGA (labeled 2). The acer is set as the primary display and all appears fine but when I'm not using the hdtv I'd like to turn it off and just use the lcd. When I turn off the hdtv I hear the sound for disconnecting hardware and the signal is cut off from the lcd putting it to sleep.

I tried the latest nvidia drivers (oh yeah, 8600GT) and it made the system super crashy with bsod's and everything. Can I disable plug and play, which I suspect is the problem, on just that monitor?

A few days ago, I dropped my laptop from less than 12 inches over the carpet. It landed on its corner. Since then, the screen won't turn on. There is no physical damage to the screen or the casing. There have been a couple of times where I was able to get it to turn on by using a paper clip to press the reset button or holding shift and f8 while I press the power button. Neither of these solutions work the first time. When I am able to get it to turn on, the screen looks perfectly fine. There are no visible problems with the colors. The only other problem related is that the backlit keyboard won't turn off when the laptop is closed. The computer works fine otherwise.

but today that dousent even work, after a restart of the computer and of the monitor the screen will dim for a secound then turn off, well it go's blank the power light is still on.
Iv played with the cord while the computer is still on and some times the picture comes back but only for a secound but then disapears again i noticed she also has an adaptore on the end of her cord that go's into the box (sorry no idea on what type of plug it is but its not the normal plug, hence the adaptor it douse have gigabyte printed on it)
I dont belive its the video card coz the picture is fine when its on with no errors but im not shore if the plug itself is stuffed.
Im not shore if its the cable coz when the screen is blank it still has the blue light and when i unplug it after about 30sec it will change to orange, so i belive the computer is still giving a signel to the screen.
And i cant tell if its the screen coz i couldent work out a way i could test it.
Im not shore what the problem is and we dont have alot of money to go out buying all new parts to try work the problem out if any one can help that would be great.

Sometimes (I'd guess 1/20) the screen does not turn on after the lid has been closed and reopened. Closing the lid again and reopening again does not work. It's not a sleep problem or similar -- if a video is playing, I'm still able to pause/unpause and hear the sound even though the screen is off. Furthermore, it's set to 'do nothing' on lid close in power options. A hard reboot solves the issue. X1 Carbon 4, W10 x64, BIOS 1.21 Please advice

Hello everybody.  I am really sad cause I think will loose my entire information.  I just bought (with so much effort) a new laptop on October 2015. Now, seven months later, when I put the ON BUTTOM, it does not turn on. I just hear all the process of turning but the screen is black.  The MAYUS KEY blink with a white light: 3 times and a pause, 3 times and a pause... Wanna know what can I do. I am completely sad and angry at the same time. My way of living is all I have there.  PLEASE HELP ME! Thanks.

When I turn the laptop on the power light comes on as does the wifi light but the screen doesn't. It's like the laptop doesn't know the lid is open. Similarly when I shut the lid it doesn't shut the laptop down/put it to sleep.I can also turn caps lock on and off etc.I would just like a way that I can access the info on the laptop such as photos etc.I have also tried plugging a vga cable in but have been unable to get a signal to the other screen.Any help would be greatly appreciated.Thanks.

I have a dv3-22330 Laptop that only recently has starting to have problems that occured about a week or two ago. On startup the LCD display does not show anything just a black screen but everything else continues to function as normal like it should, i have tried all of the suggested ideas like taking out all the power and holding the power button for 60 seconds to get rid of any charge that maybe triggering the failsafe.

The strangest thing is that im writting this thread on the very same laptop, after some testing done earlier the laptop screen will only turn on when the power cable is plugged in but will not turn the screen off when taken out again.

Laptop + Battery = No Screen
Laptop + Battery with power cable plugged in after or during boot up = Screen on
Laptop + Power cable = Screen on
Laptop + Battery + Power cable = Screen On

This surely rules out that the common suggestion that i found like backlight, inverter ect isnt the problem and this also does not sound like a dodgey cable as the power cable would have no effect on a wonky cable. The most obvious problem might be that it has to do with the Power Saving settings but they are set so they also do not turn the screen off in anyway although with the power cable plugged in makes the screen come on you would be lead to believe it is.

Any help to this problem would be greatly appreciated as this is baffeling me.

Last 7 months I bought an HP ENVY 15 TOUCHSCREENAnd when I'm using it, the screen turns pink and flickering.How can I solve this and does the warranty still cover this issue. Also when my laptop turns black there is a pixel that turns red but when the color is light it does not show.I'm looking forward to solve this problem thank you!
