Preferred Solution: Screen goes black with one white flashing dash

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 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!

Go into your BIOS and verify that the hard drive is listed as the first boot device. If it is, it sounds like your mbr is corrupt, or your hard drive is damagedI'm still learning Vista, not quite sure if fixmbr is the same or not.

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.

A:[SOLVED] Boot problem- blank screen flashing white dash

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.

Hi! Sorry for opening a new thread but this is just so serious and I am so stressed out about it that I didn't have the patience to search if the thread is already open.
I have a black screen and white blinking dash problem. The thing is, I can't even type f2 or f4, or anything whatsoever. It is not reacting at all to the keyboard. It's the second time this is happening in 2 days, every time I turn it off (properly) and try to turn it on, it does that. After a lot of hopeless trying to turn it on or make f2 or f4 work, it just starts working again normally... And now I finally turned it on after I spent the whole morning trying and I'm working on saving all my files, but now I'm scared to turn it off. What do I do?? What is wrong with my computer?

My computer, which was running windows 10 without much issue, is now completely unusable for reasons beyond my comprehension. After bios messages I now only have a blinking white dash on a black screen.

I have tried various repairs, with the windows recovery usb. All automatic repairs fail due to the disk "being locked", so i have tried a few guides which involved bcdboot commands which have failed to fix anything. One command was bcdboot g: which gave an error like failed copying boot files (i forget the exact wording) .

Could some kind soul point me towards a fix, im tearing my hair out! Many thanks!

Hello, I am trying to install Windows XP (because Windows 7 is damn slow) Corporate Edition 64-bit but after the Copying Windows Files setup portion, the setup wants to restart my computer, but after the motherboard logo, I just get the blacnk screen with white dash - if CD is inserted I get "Press any key to boot from CD....." and a white dash at the end with nothing happening. I've searched for a solution everywhere, but I didn't find my case. I have installed XP atleas 20 times on this computer, and I've never had such problem before. I thought it could be because of the 64-bit version, but after trying to install the 32-bit version I have got the same issue, which has never happened before. Windows 7 installs perfectly. I have: removed the CD from the drive; Updated the BIOS to the last version; Tried running in safe mode and nothing helped. My computer specs are: Processor: Intel Pentium DualCore @ 2.80 GHz, 4GB of DDR2 RAM, 650GB HDD SATA2, ATI HD 4770 512MB DDR5 Graphics Card, American Megatrends Inc. 0502 BIOS. I hope there's somebody out there to help me because I really want XP.

A:Black screen with white dash after first portion of Windows Setup?

Seems that Windows XP installation is not detecting or having problems with your SATA2 drive.

Try going to BIOS and Switching the SATA2 drive out of RAID mode if possible see if that helps.

Windows Xp has issues with SATA2 Drives.

Or you may need to slipstream your copy of Xp with sp2 or 3 if your cd is only SP1 for it to recognize and work with SATA drives. Also with SATA drives I believe Windows XP only recognizes 128GB 137GB SATA drives.

First, i restarted my stupid computer
Then, i got that grub error.
I happily fixed that.
However, when I restarted it again,
I got stuck at black screen with stupid blinkking white dash.
So I use the Recovery Disc thingy
And i clicked that first option.
Then it says, something like
unable to fix it.
Then it says that the stupid missing boot thingy is missing.
Googled for solution.
Tried those command prompt like
Fixmbr or scanos
(it says theres an installation
I typed Y for yes and still,
That boot missing chkdsk thingy still pops up)
Remove hardwares (wait whats a hardware is it those usb thingy?)
Checked the BIOS which I googled again for its meaning.(and yes, it is in order)
But never worked.
So any suggestions or explain with more detail?
Because I have no idea about these computer stuffs.

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

'PLEASE SELECT BOOT DEVICE

SATA:3M-STM3250318AS
CDROM:3S-TSSTcorp CDDVDW SH-S22'

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.

Today I started up my pc and after the BIOS screen (the place where you can press f8-f11 for various options) it went to a black screen with a blinking underscore in the upper left corner and stayed there indefinitely. It did this even after reboot.

I tried using the diagnostic tool and everything it tested passed (including HDD). I did this test twice and the same results were produced.

I also googled for similar problems (one topic mentioned that the op disassembling his computer and physically tapping a chip on the motherboard caused it to work) but I have no experience with taking apart my computer and i do not want to break it accidentally. I did however chance upon a topic advising him to do a CMOS reset which apparently helped that op, so i looked through the various options on the BIOS page. There was one option (f10 I think) mentioning CMOS on its fourth sub-window, so i pressed the reset option but I'm not entirely sure if I used the right function.

I uninstalled kaspersky pure and replaced kaspersky pure for kaspersky anti-virus yesterday, dont know if this was the cause.

I am using windows 7 64 bit. However, I am also not able to tell whether it is Windows 7 Home Premium, Pro or Ultimate because I have no idea how to access to the start menu or the run dialog from what amounts to basically only the BIOS screen. As such I cannot tell which is the proper windows 7 SP1 ISO that I should be using. Can anyone help?

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 have been having problems with my Dell Dimension 5000 since this morning, basically I switch it on and all I get is a blank blank screen with a white dash blinking in the top left corner.

I can't access safe mode or bios settings using the function keys and I can't get further then this blank black creen with flashing dash.

I have taken out my gfx card and cleaned the dust out of the fan, checked all the cable connections inside and out. I also checked other posts for solutions but could not find any that related to mine as I can't access anything. I have also checked the Dell Diagnostic lights which indicate:


Other failure has occurred.
Ensure that the cables are properly connected to the system board from the hard drive, CD drive, and DVD drive.
Check the computer message that appears on your monitor screen.
If the problem persists, contact Dell.

Dell don't seem helpful as the computer is out of warrenty and I even get passed around or hung up on. Only thing I can think of is that my hard drive might of gone as it makes a reading noise about five times then I hear nothing even though I replaced the HD about two months ago.

Sorry for the essay, hope I can sort it out!!

A:Flashing Dash

Take the drive out, mount it in an external enclosure, attach it to a working computer by USB cord and copy out files that you can access. After that run hard drive diagnostic utilities like hitach drive fitness test and check to make sure it is completely fine before reinstalling in the original computer. You can try booting into safe mode, or last known good configuration or you can try a repair install of the OS. If nothing else works, format and reinstall the OS from scratch.

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)?

Hello,

Before reading the below paragraph NOTE: I used the windows 7 upgrade advisor to tell me if there are any compatibility problems and nothing came in.

I recently installed Windows 7 on my Acer Aspire 6530 and it worked great, no problems at all! I thought it was amazing due to microsoft's previous attempts. Anyway in the excitment I attempt to upgrade my other Acer Aspire 7720 which also is a laptop, and I boot it while on the computer so I can save my files, and then it booted with a black screen with a flashing white dash, so I attempted to install Windows 7 by simply booting it with a CD, after all of that, it has the same result.

Obviously all my files are gone, but I was smart enough to make a back-up which it is now on, but what I want to know is there is anyway to fix it so I CAN use Windows 7, there shouldn't be any problems upgrading my system, what has gone wrong?

Anyone can suggest any fixes or causes???

Maybe clearing the BIOS could help. Look at the motherboard menu, there should be a jumper which you can set to clear the BIOS.

If you can still enter the BIOS by pressing a certain key on startup, then you can choose Load BIOS defaults or some similar setting.

Now it has, but my PC won't boot any more. All I get is a continuous flashing dash, or hyphen, or whatever blinks before Windows' XP progress bar appears. What's my next step?

I'll continue to check this thread so if you need any more information let me know.

I am having graphics problems with my IBM Intellistation Z Pro desktop. The graphics card is a NVIDIA Quadro4 980 XGL. Every time I try to open a game, or even Google Earth, I get white and yellow specks flashing all over the screen, the computer freezes up, and I have to reboot it. I have reinstalled the drivers, and cleaned the dust out of the computer, but neither seemed to fix the problem. My operating system is XP. Any suggestions you can give me would be appreciated.

Thanks

Hello. I have a compaq mini that was infected with the pallidium virus. After following the instructions for removal using RKill computer rebooted and now it only starts with a black screen with a flashing dash. I cannot access anything at all. I took out the battery, still nothing. I thought I would reinstall Windows XP Pro but I get the error message that it did not find hard disk drives? Any ideas.

Thank you.

Hello,

So on my computer, something strange happens when I uninstall UxStyle. It has broken my Windows install once and it has done it again. The first time, I kept on doing system restores to see what was the problem that made that black screen. After trial and error, I narrowed it down to UxStyle. So, I deleted Windows 8 and installed Windows 7, which is what I wanted in the first place. Now, I decided to triple-boot Windows 7 with Vista and 8.1, and it has succeeded. I reinstalled UxStyle thinking it was just a problem with my old Windows install, and then uninstalled it after a few days since I felt like the regular look was better. I rebooted Windows and the same effect happened.

So, I would like to know if I can get and replace those three patched DLLs with unpatched DLLs for Windows 8.1. Could I just change the broken ones to have .old next to them and then place the ones I get here there? Also, would sfc /scannow work?

Hello lct01a, and welcome to Eight Forums.

A sfc /scannow will attempt to repair any modified or corrupted system files, so that would be a good first step.

Not sure how else to describe it. I started up my computer this morning and when it loaded the login screen it started rapidly flickering in white with very small pink pixels visible all over the screen. The login screen was not visible at all, the screen just turned white. I could see my mouse pointer and I could move it around, so the computer didn't freeze or anything. I then performed a hard reboot and now everything is back to normal. Never seen anything like this before, and I'm running on a clean install of Windows 10 Home x64. This is not a problem with my monitor as I reconnected all cables during this. My computer itself is pretty much new, less than a year old.

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.

Hi, Before anything, I would like to apogolize for my bad English, I?m like so many french guy bad at other languages ! I got a problem with my Thinkcentre 7635-W1n. It?s a computer I bought with W10 OEM pre-installed on a HDD. However, I wanted to replace this HDD by a SSD. So when I receive the computer I make the replacement and I erase the HDD for using as a save HDD. After create an USB boot with Rufus, the screen displays  Error 1962, no operating system found . After many tries :Convert the SSD in GPT format and create an USB boot UEFI compatible (yes, I was able to use Gparted from live USB) ;Change thing in the BIOS : but there is no thing about Secure Boot/Legacy in the settings. But this recent tries don?t lead to boot on USB. Now, after try booting on USB, I have a white dash sign in the top left corner. I read that there is a problem with the Lenovo with an OEM OS but can?t find the solution myself. Thank you for reading my post and have a nice day

I got my Radeon 6570 today and I installed it, but now Windows won't boot it just gives me the blinking white dash. So I removed the card, switched back to onboard from BIOS and it still didn't work. I tried a lot of other stuff but it didn't work so I reinstalled Windows with the graphics card removed (Hoping it would reinstall the drivers for the onboard video) it didn't. So then I tried booting from an old Linux disc I found and it worked (how I am typing) but Windows still won't. Any help? I ran a diagnostics text and everything is working, and I can even access all my personal files on my old Windows install from Linux so I know that it's active.

check inside your case for connections to your harddrive. also check your bios boot settings and see if the os drive is first.

Bit of a long story but here I go.

I have 2 Radeon 6950 with the crossfire thing set up, it's been working well for over 2 years.

Over the last few weeks I've been having issues, mostly while watching videos (usually HD and/or full screen). The video will freeze, the audio will loop, then eventually the screen goes black and I get an error message saying "Display driver has stopped working and has recovered".
Sometimes it didn't recover and I have to turn the computer off.

What's now happening is it will freeze at the windows start up. Then after resetting I will get to windows in very very low resolution and in black and white.

So I 're-seated' the cards. I couldn't notice any obvious damage to it except the fans were very dusty so I cleaned them.
Boot it up and I still get the black and white.
I checked the device manager and it said one of the cards was having problems, I uninstalled both drivers from that menu (not quite sure if I should have done this) and for whatever reason it's now working.

However it now seems one of my cards is not being recognised. Only one display adapter is shown in the device manager and AMD catalyst only recognises one card too.

What's the best course of action to determine what's wrong with what card (still not quite sure which one it is).

Hi everybody,
 
First of all, sorry about my English.
 
Few days ago, I was working on my laptop (ASUS X5DI) and when I decide shuting down, I realize that needs to intall updates. I let him to shut down by itself and do it fine without any problems.
 
Next day, when I turn on the computer again, the show me this (its spanish but i think you'll know what screen is):
 

 
I thought then, that something in the update process went wrong, so I try to fix it. First, I tried it by click on the "Repair Startup" option in that image menu. A message box that wants to select a keyboard language appeared but after that and some comprobations of the process, It said to me with an alert box that it couldn't be possible:
 

 
Then..  this other screen appeared:
 

 
I click on the options, even in the prompt option, and tried to fix it with bootrec commands like /fixboot or /fixmbr but nothing fix the problem.
 
So... What I decided? the solution that "never fail" ... format all my pc again and get a "new" computer hahaha..
 
I get into the BIOS and change the boot order to start from CD/DVD. Save changes, introduce the Windows 7 disc and restart. 
 
I realized that my computer cant start from cd/dvd because that white blinking cursor appears on the top left of the screen.
 
I tried with different CD/DVD even Ubuntu CD and always the blink cursor appears. So... if I use HDD boot in BIOS appears the screen on the top... Read more

Hey guys, here I am again with another failure.
Today morning I woke up to my windows refusing to boot. It just does the white dash blinking in the top left corner (it jumps down a bit at first, then just keeps blinking endlessly). I'm aware that this can be a result of a poor shutdown or a crash or modified system files or program installation, or whatever. The thing is last night I was using the computer fine and I didn't install anything, modify anything, and it shut down correctly (as far as I know - after I clicked shut down I shut off the monitors and went somewhere else, and just when I came back it turned off so I assume it was fine).

I've tried a number of things already. First, I'm booting from an Ubuntu CD right now and my files are all fine and intact on the C:\ drive. Second, I tried running my Windows 7 CD to go into the recovery system and tried a bunch of things.

The recovery thing doesn't detect my operating system, first of all, but I've had this issue before. I remember that I got it to work somehow, but I don't remember how. I think it might have been a disc that I burned with a modification that allowed it to detect the system (I used some tutorials over at sevenforums.com, can't remember which ones now though). I'll look for the CD, I might have it somewhere.
EDIT: I found what I presume is the CD but it doesn't even want to boot. I'll try looking for whatever I found before and make another one, I guess. But if I could get it to det... Read more

A:Help - Windows won't boot, white dash blinking endlessly.

From what you have written, this should be impossible but I suggest you to press F8 right before booting into windows, and select 'Use last known good config'.
This issue sound really hopeless, but if you could manage to boot into any windows which is on another partition (if you have any), you could rebuild the MBR manually (master boot record) which stores the OS information.
Do you have another disk/partition?
If yes, the best would be to install W7 on it (takes 20mins) do the above things (I will explain it further if you have another partition) and then boot back into your original OS and would be able to delete the 'blank' windows 7 installation files from the orher partition.
