I always get a flashing white screen whenever I boot up my Dell Inspiron 15

Q: I always get a flashing white screen whenever I boot up my Dell Inspiron 15

I have a Dell Inspiron 15 and whenever I boot up the computer, either from sleep mode of from when it's off, I get a flashing white screen. The screen has vertical zig-zag lines on it that are spaced out and it just keeps flashing. I have to turn my computer on and off enough times for it to finally boot up properly.
I've had the computer for a little over a year it has an Intel graphics card. I tried to restore to an older system image, but I have no system images on my computer. Would resetting the computer help? If so, how do I preserve Microsoft Office on my computer?
This is a really frustrating and time consuming issue, and Dell has really *** customer support, so any help would be greatly appreciated. Thanks a lot.

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.)


I'm facing the following issue with a Dell Precision 5510 laptop with latest bios 1.2.14 A13. It appeared suddenly, I just rebooted a working system.
The laptop does not boot anymore and the Dell logo is not shown, however, the diagnostic battery led blinks 2 times white and 2 times amber.
According to the error table that I found here http://www.dell.com/support/article/uk/en/ukdhs1/SLN295101/EN#2016_to_Present that means
System Board : BIOS, ROM Failure
and the suggested next steps are:

Flash BIOS to latest revision
If problem persists contact Tech Support for further troubleshooting
Did anyone had a similar experience?
How can I re-flash the BIOS from a non-booting machine?
I found some tricks for the Dell XPS 9350 (extracting HDR and ROM files from bios executable and plugging a USB drive) but they do not seem to apply to this laptop.
I found http://www.dell.com/support/article/uk/en/ukdhs1/SLN300716/en but I'm still unable to recover the computer. I keep getting the 3:3 blinking pattern, even after I put the latest BIOS (renamed to 'BIOS_IMG.rcv') into a newly formatted FAT32 USB stick (2 GB). I also tried with different USB sticks, and both USB ports.
Any help is really appreciated
Best regards,

I have an Hp pavilion a1226n desktop computer and shut off the power this morning during a bad storm. I used the regular procedures and shut it down correctly, but when i tried to boot it up earlier this morning, the only thing that comes up is a blank black screen with a flashing white dash in the upper left hand corner. I have already tried to remove reset the BIOS by removing the battery and then later restarting, but it did not help at all. Also, it wont even boot far enough for me to start in safe/real mode. Any suggestions?
Thanks for the help

Hi sherm12789 and welcome to TSF

Start up your computer by either tapping the F1, F2, F4, F6, F8, F10, F11, F12, or Delete keys to access the systems BIOS. For the exact information on what key to start up the System BIOS refer back to Original Manufacturer System Documentation.

After getting into the BIOS, look for a page that would have something like, eg. PC Health Screen or System Monitoring Page. When you have found a page similar to this post back what the BIOS says for your temperatures, voltages, and fan speeds.

This recently started happening. Sometimes when I boot my computer, it displays a white screen with colorful pixels scattered across the screen. It starts by constantly flashing from the white screen to black. Eventually, it stops at the white screen. I can still see my mouse pointer though and move it around. It's happened three times now and it only happens every few boots. I have to hit the reset button on my case to get out of it. Any idea? Thanks.
Here's a picture of the white screen: http://i.imgur.com/mPLw38I.jpg
OS: Windows 10
CPU: AMD FX 8320
I have also attached the event error log.
EDIT: I think the problem has to do with the constant spamming of this in the logs:
"Display driver nvlddmkm stopped responding and has successfully recovered."
So GPU drivers or GPU failure? :\
By the way, this only happens on SOME OS BOOTS. Games/video run fine without crashing if the OS boots up properly.

Hi. I'm currently having some problems with my Dell Inspiron 5000 laptop computer. For a while now, the screen flickered constantly, so i had to tilt the display to get a clear picture for the moment. However, now the screen goes completely white when i boot up. I've tested Windows by connecting the laptop to my TV via an S-Video cord, and it works fine. There's something wrong with the display... Does anyone know how to fix it? THanks in advance.

A:Dell Inspiron 5000 White Screen


My name is John, and I work at Dell headquarters.

If you don't see the problem when hooked to an external display, that pretty much rules out the video card. The only thing you can really try is reseating the video cable, but if that doesn't work, you'd probably be looking at a new display.

Here is a link to the service manual. The second section should show you how to replace the display (and in that, you should see how to reseat the cable):

I have a Dell Inspiron 14 5458 laptop that sporadically flashes a bright light (almost like taking a photo), and also the screen flickers quite frequently while I am working on it.
I have Windows 10 and an Intel Core i5 processor and it comes with a touch screen. What can I do to stop the flashing and flickering? I have taken it twice to a computer repair shop, and they couldn't fix it. Please help! It's driving me crazy.

Hey everybody,

Im going crazy cause my computer will not make it past the initial dell startup screen with the two options of pressing F2 or F12. After it loads that page it simply goes to a blank screen with a flashing underscore ( _ )

I would be extremely grateful if anyone can find me a solution to this problem. Ive tried both F2 and F12 and changed just about every setting i could think of including the order of process to boot. I ran diagnostics and nothing worked. I removed the battery and ran off of a/c power and still nothing. I also unplugged everything from the usb ports.

Some info about my computer: dell inspiron 1525 running on windows vista

Thank you to anyone who can help

Sounds like you are experiencing hard drive failure, or hard drive corruption. I just repaired a computer with the exactly same issue, and realized that the partition tables on the drive was corrupted. Then after further diagnosis, realized that the partition tables were corrupted due to the drive physically failing.

Do you have a Dell partition for the hard drive utility?

Starting Dell Diagnostics From Your Hard Drive

The Dell Diagnostics is located on a hidden
diagnostic utility partition on your hard drive.
NOTE: If your computer cannot display a
screen image, see “Contacting Dell” on
page 50.
1. Ensure that the computer is connected to an
electrical outlet that is known to be working
2. Turn on (or restart) your computer.
3. When the DELL&#8482; logo appears, press <F12>
immediately. Select Diagnostics from the
boot menu and press <Enter>.
NOTE: If you wait too long and the operating
system logo appears, continue to wait until
you see the Microsoft® Windows® desktop;
then, shut down your computer and try again.
NOTE: If you see a message stating that no
diagnostics utility partition has been found,
run the Dell Diagnostics from the Drivers
and Utilities media.

I have a white screen upon startup. I was able to use my laptop when plugging the VGA cable in the back to an external monitor but that only works with a few tries.
I notice if i put my laptop on sleep for less than 2 hours the external monitor works.
Any time longer and I have to start the process of removing and inserting the plug and playing with my external monitor so it can detect a signal, it usually takes a few tries and a few minutes.
The white screen is always on my laptop throughout the process and even when the external monitor works.
Just determining if i should replace me screen or ribbon video cable or check my connection to my vga cable or could it be my motherboard.

any help or direction is appreciated.
Thank you!

A:Dell Inspiron 15R N5110 screen problem - white screen & external monitor works if I jiggle the plug

We need to isolate if the issue is with the LCD or the video card. So, turn off the system - press and hold the "d" + power key to turn it back on - this should initiate the LCD built in self test. You should see a screen with solid changing colors and the system would beep. If you see this - the LCD is fine. If you do not see the colors changing - then repeat the step again - but this time - swivel the LCD back and forth and see if there is any display. If the display is intermittent then the LCD cable needs reseating/replacing.
Also, turn off the system and press and hold the "fn" key + power button to turn it back on - wait for a few minutes. If you do not see any display, the system should start beeping. Count the number of beeps per cycle. At any point if you see the screen with solid colors changing - the LCD is fine. The issue is with the video card/motherboard. If do not see the changing colors - then we would suspect the LCD.
Test the system with another VGA cable for the external monitor.
If the system is under warranty, then please send me the service tag of the system and your contact details through a private conversation. Or you could use twitter - @dellcares - we can DM through twitter and help you fix the issue.
Keep us updated.

my Dell INSPIRON 1564 is only two month old. It has a problem that screen goes blank white while booting. This problem also occured 2-3 times when I was working on it. I re-loaded the video card drive supplied by Dell but problem remains unresolved. Dell support centre is not responding to the problem.
Will be thankful if some one suggest me the remedy/ solution for this problem.

A:DELL INSPIRON 1564 , Screen goes white blank

I bought Inspiron 1564 around 6 months ago. The problem which I am having for the last 3-4 months is that the screen goes completely white when the laptop is powered ON or when watching videos on youtube, media player or switching screens too fast (b/w full screen and normal mode in a movie) or when Windows 7 asks for permission to execute any installation prog.
Firstly I thought it is a Windows related issue. I searched a lot of forums but no success. Updated Video Drivers from Intel, Dell to the latest time to time, but no result.
Couple of days ago, I realized that the screen goes white in the Setup menu (F2) as well, showing that it is hardware related. Occasionally, some lines appear on screen during Windows boot (like in case of VHS when video tape is too old).
I got some hope after reading above post. Can anyone help ? Specs are as under

I recently had to replace my motherboard on my Dell Inspiron 7520 laptop, due to the old motherboard failing to even power up. After fitting the new motherboard (taking care not to damage the internal components), I restarted the laptop, only to discover that the main display wasn't working correctly. It was only showing a blank white screen. I connected the laptop to an external VGA display, and managed to get it to project through the display. I used that to flash the new BIOS. However, I couldn't work out what was wrong with the display, as the video card and software seemed to be working, and the display was responding to brightness and dimming commands from the keyboard. I decided to reboot into safe mode using msconfig, but now the laptop still has the white screen issue and won't project to an external screen either, even once I've pressed F2 to enter BIOS. I've tried the power on + D to try to run a screen test, but nothing happens. It only turns on for a few seconds, then powers down again. Any help will be greatly appreciated.

Hello, the problem is with random generated white bubbles on touch screen.How can I solve the problem?I read that the problem is on hardware level.Now I try to use system with disabled touch screen driver and I wait results.What your best practice in this condition?

A:Dell Inspiron 15z 5523a White Bubbles on touch screen

Run the built-in self test -- hold the D key through powerup.
If the fault shows on the screen test, replace the upper half of the system (display panel, touch panel, bezel, frame, hinges and cables are all one assembly).
If the fault DOES NOT show on the self test, it's more likely a faulty GPU - replace the system board.

With motherboard removed and power supply connected, monitor connected, ram in, CPU in, HD connected and Case Power Connector for front Push-Button "connected" the system acts like it's going to start but nothing shows up on the display and screen shows No Signal.
However, if I unplug the Case Power Connector for Push-button from the motherboard and start the system by shorting the two power pins on the motherboard ....then the system starts normally and the display works.
Does this indicate that I have a bad power connector, bad power button?  How do I solve this problem?  The power button is white when it does not start up.

Good Morning all,
I have a Dell Inspiron 15 (7559) Laptop.  When I went to go power on the laptop, the keyboard lights up, but nothing appears on screen.  I also noticed the "Battery Light" indicator on the laptop was flashing.  It would flash white four times and then flash orange two times.  In the beginning I thought my laptop had died so I went ahead and charged the laptop.  I was able to charge the laptop, so I'm thinking that the battery is still good.  I'm hoping someone out here on these forums can help me diagnose and resolve this issue before I contact tech support.  Any information you guys/gals can provide is greatly appreciated.

I can't tell exactly when this started as I have upgraded the NVIDIA drivers as well as the Dell bios and switched from running the onboard Intel HD 630 to GTX 750ti , but now on a cold boot, with the fast startup off, the screen flashes white for a sec after the Dell logo. It could possibly be white noise but I can't focus on it fast enough. It doesn't happen on restarts. I'm connected via hdmi out to a LG TV.
Dell XPS 8910 using the NVidia GTX 750ti and an HDMI TV as monitor Bios version is 1.1.0 ,1.1.0 Original version was 1.0.9, 1.0.9, can I revert back to 1.0.9 ?

A couple of days ago, I'd fallen asleep with my laptop on and thus it went to sleep and eventually into hibernation. When I went to turn it on in the morning, the hard drive whirred as usual and the Dell loading screen came on (the screen with the Dell symbol, loading bar, and setup/boot options), but after that, my laptop went to a black screen with a flashing white underscore and wouldn't boot.

I restarted it manually a few times (as much as I hated to), and eventually hit F12 and selected the option of booting from the internal HDD. I'd thought it was maybe a one-time thing, but I wouldn't be so lucky.

Today when I got home, after my computer had been shut down from 7am to 8pm, I went to turn my computer on and the same thing happened. So, as last time, I restarted it manually and selected F12, but my laptop didn't even go to the options menu; it went right to the flashing underscore. I restarted again and selected the boot from internal HDD and it booted like it usually does, but I'm worried that this is going to become a trend.

My laptop -- a Dell Inspiron 1545 -- is only 2 years and four months old. I take great care of any electronic I own and am adept when it comes to computers, but not with this type of thing. Anyway, tonight I did a scan with System Checkup for free, and it told me that I have signs of physical corruption on drive C.

A:Flashing underscore after Dell loading screen, Windows 7, no boot

The first thing I would suggest is that you back up all your important data to an external source, if you want to wait until you get the external hard drive back (wherever it is) that may be beneficial if you have a lot to back up, or use CD/DVD's.

Then I would run the manufacturer's diagnostics to get a clear picture on the health of your hard drive. If the results indicate the drive is failing then you will need to replace it, but if it comes up clean we can proceed with further diagnosis.

Identify the make of your hard drive and then use one of the links below to get the manufacturer's diagnostics for ISO (CD) not the one for Windows.

When the download is complete right click the file and select Extract Here and burn the image to a CD.

In Windows 7 right click the extracted file, select Open With, then select Windows Disc Image Burning Tool then follow the prompts. For all other versions of windows (if you do not have an ISO burner) download this free software. ImgBurn
Install the program and start the application. Select the top left hand option to burn image file to disk and then on the next window click on the small yellow folder icon and browse to the file you have downloaded from the links below. Then click on the two grey discs with the arrow in between (bottom left) and leave it to complete the operation.

Boot the PC into the Bios setup and set the CD/DVD drive to 1st in the boot sequence. Insert the disk in the drive then reboot and ... Read more

I have a Dell inspiron 530 that will not boot. Its running xp professional with a core 2 quad. When I turn it on i hear one beep and it sticks at the boot splash screen. F2 and F12 do nothing. So far I have tried the following:

1)Swapped hard drive out with a known working one.
2)Removed both sticks of 1gig ram and placed them in different slots.
3)Swapped out one stick of ram at a time to determine if one is defective.
4)Swapped out all ram with known working ram.
5)Removed radeon graphics card.
6)Tried to do a repair on windows from a disk but I cannot get into the boot settings.
7)Tried unplugging everything except the monitor and power cord.

After attempting these steps I still receive the same results everytime. I was thinking about removing and re-seating the processor, but I figure someone with more knowledge than me would have another suggestion for me to try. I fear the worst for this PC assuming it is the motherboard or processor. No new hardware or software was added to this system when the issue started. Thanks in advance for any help/suggestions.

I was just watching a movie on my Dell Inspiron 1564 which I have been using for the last 7 years. I know it's a bit old but has worked perfectly for me until today.
I close the lid so that I move my laptop to the balcony. When I opened it I saw a black screen, the power led was on and no hdd activity was shown on the respective led. So after waiting a while I manually switched it off through the on/off button.
After that I switch it on again. The power led is on. From the led showing the hdd activity I can see that the system tries to boot the hard drive but fails. However there is no Dell starting screen, boot options or anything. At the moment when this occurred I was logged in an Ubuntu 14.04. I have a dual boot Dell with windows 7 and Ubuntu 14.04.
I am aware that probably this is not something I can personally fix. However I am really stressed about my hard drive because I am at the end of my thesis and although I have backed up many things I had not for the last 2 weeks when a lot of serious work was done. Could someone try to narrow down to the possible reasons for this incident?

Upon a reboot last night, I got a blank white screen. Could still hear Windows 7 starting up, so I entered my password and it went to windows. CTR+ALT+DEL x 2 to turn off. Tried turning on again with same results and held power button to force turn off.

Welcome elfinwood.

Just to clarify... It sounds as if you have been playing Second Life with your computer for a while, which has always worked fine, until recently, where you have this flashing screen problem? When does this problem occur? Is it after playing the game for a while or as soon as you start the game? Or does it start as soon as your turn on the computer?

If it is when you start the game, does it do it when you start other games (games that require good use of the graphics card/system)?

> When was the last time you updated your drivers?

My computer will not fully start up because it always gets stuck on a flashing white line on the top left corner. I have been having issues with my video card recently (ati radeon 4850) where a red light will go on and my monitor will go black therefore making me have to hard reboot my computer. I do not know what this red light means so if someone could help me that we would be awesome as well. This line I was stuck on happened after one of the red light issues so I hard rebooted and that's where I'm stuck now. I am trying to reformat now and it is telling me that no device drivers were found and make sure the installation media contains the right drivers, which makes no sense to me because that has never happened to me, please help.

A:Flashing white line, computer will not boot.

Never mind, this post fixed it. PC won't boot; blinking white light in top left
I put those commands in prompt and it worked. But could someone still help me with this red blinking light I'm still having on my video card.

Hi, I've been having this problem. When I start my computer, the whole screen is white for awhile, then it turns black. There is no windows startup logo or my computer brand logo. Then my screen starts flashing and the power button on my monitor blinks and the monitor makes TOK sounds every 2 seconds and then the screen flashes and starts doing that over and over until it decides to make the whole screen white and stay like that. Here's what it looks like: 
I tried manually restarting my computer by holding the power button and after a few tries, sometimes, if I'm lucky, it will let me login and then everything is fine.
Today, I went through this process and today I tried turning off the monitor when the screen was white. It restarted and black flashing but made the screen turn white faster. I just kept trying, turning the monitor off and on again because I didn't know what to do. Then I was so lucky, the login page for windows came up and I was able to login; now everything is normal. I can go online and everything without any problems until I shut down my computer and start it up again. Then it's back to square one.
Can anyone help me fix this problem? Should I buy a new monitor? I've had this one for a few years, but my desktop is new; It's one year old in 3 days. (April. 4)
Thanks in advance!

I came across a Dell Inspiron N7010. Everytime I turn it on, the Dell symbol comes on, then the bar goes around and fills, then it should start to load windows vista. Well when it starts to load Vista it stops and give me a blue screen that says different errors almost every time it does this. The last time the error said something like


and it also game me a crap load of stop error codes, here is one of them

0x00000050 (0x8607FFF8,0x00000000,0x8BAD1BD3,0x00000000)

Now I know these are stop error codes from doing some research but I can't fix them using that windows tool because I can't get into windows at all!! lol sorry, frustrated. I kept reading about a windbgtool or something similar and they would direct people to do things from the desktop when windows is on and working. Well I can't get passed it and I'm totally stumped on where to go from here. The inspiron N7010 has an i5 processor which is pretty nice and I have 8gb of DDR3 6400 16000 800mhz ram and a 120gb SSD to go with it to, so it would be a nice working laptop if I could get past this blue screen problem!! Someone please help me.....

u can try connecting an external monitor from a desktop if u have one or borrow one and see if that monitor shows anything without problems.it sounds to me that your monitor on the laptop has gone bad.. the led modules that light it up have gone bad or your video card might be bad.it could also be that the motherboard or hard drive is failing.usually if just the monitor is bad it should load up with no problems.hope this helps u.

My Dell 1720 Laptop (Vista) had the following error:
The file header checksum does not match the computer checksum

I tried to restore to factory settings F11 but the laptop wouldn't let me.

Tried to restore from Dells disk but the computer wouldn't load the restore disk.

Now the computer on startup has a black screen and will not boot up. None of the F keys will work. Keyboard was working fine until this error.

I decided to purchase a new hard drive. Installed the new drive and the computer is doing the same thing.

Any ideas?

A:Dell Inspiron 1720 Black Screen Will Not Boot

1) What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?

2) What do you mean the "laptop wouldn't let you" restore to factory settings?

3) What do you mean it "wouldn't load the restore disk"?

4) You replaced the drive and now have a blank hd in the system?

I have a Dell Inspiron 9400 with Windows XP installed. I have the laptop since April 2007.
Yeasterday I left the laptop in stand-by for about 1 hour, when I got back the screen was black and could not be revived in any mode.
I have switched off the PC by pressing the power button until power went off.

When I try to start the laptop the Dell logo would come on with a weird pattern of green dots in the back ground, then the usual XP logo would come on, still green dot pattern all over the screen and then the screen would go blank.

I have ran all the available system diagnostics for Memory, Harddisk and system componenents at start-up and they all passed. In addition the laptops power sources are working well.

Then I have run the genuine Dell-XP CD Rom and run the 'Repair Installation' option.
This would run normally and even the screen was normal until after the first Boot request. Then rebootet the PC and configuration would go on for about 10 minutes ... then the screen just blanks out again.

Please help ... I need some fresh ideas on what else I could do.

I have a dell inspiron 8100. It's giving me the blue screen and last time this happened I just "repaired" windows xp using my cd. This time, when I go to the setup screen, in page 2 "Boot order", at the top of the boot devices it says "Configure Setup is disabled." The boot order is Internal HDD, then CD/DVD/CD-RW Drive, then diskette drive, then modular bay hdd, cardbus NIC, APR NIC and last Mini-PCI NIC. I just want to move CD to 1st but I can't.

"u" and "d" to move devices up and down is locked. Up and down arrow does not move the highlight up and down like it should so I can't hit enter, or spacebar, on the one I want (CD). Right and left arrows do nothing. The only commands that do anything on this screen are Esc, which obviously escapes out of the setup, and Alt-P changes to the next page, but that doesn't help. And PgDn and PgUp which just moves the right side up and down which is just for information purposes.

It is a Dell Inspiron 8100 1200U Setup and BIOS Version: A11

Any suggestions?

I'm sorry for the lack of any technical terms used to describe this but I'm a complete novice with computers.

I was watching a video when some warning messages popped up saying something like harmful stuffs trying to access your computer, then it restarted. Now it starts up, goes to the motherboard thing, goes past that then hits a black screen with a little white line flashing in the top left corner.

I've tried to use F8 to enter the safe mode start up but when I press F8 it comes up with



I tried the SATA option twice, first time the white line vanished so it was just a black screen and then it restarted. Second time it just went back to the screen with the white flashing line.

Any help in sorting this out would be greatly appreciated.

I have an HP Pavillion dv6000, running with Windows Vista Home Premium.

When I turn on the computer, the HP intro screen turns on but then immediately goes Black with a white flashing dash in the top left screen. I can not access F8, safe mode, etc. I can only access the basic set up menu.

I never received a restore, or a Windows XP disc. Ive come to terms with the fact that I will most likely would lose my files and am willing to do a restore, but I can not get onto the log on screen. Do i need to see a tech? Please be advised I am not tech savvy and just want to get back on to my computer

Any help/links/disc downloads would be appreciated.

Thanks in advance!
