Preferred Solution: flashing white dash line in corner of screen

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.)

A: flashing white dash line in corner of screen

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.

Hi,

Apologies if this question has been answered elsewhere.

I have a Dell GX Piece of $H!t and when I boot it up all I get is a flashing white line in the top left hand corner. I don't see a BIOS screen. Am happy to install linux on it - just need to get to the BIOS screen so I can boot up off a USB drive.

Any suggestions gratefully received!

Thanks,

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

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.

I have seen this problem once before [posted in a different forum on this site] but it was a problem someone had on a laptop and it was for Windows XP.

I am using a desktop PC [Windows 7- HP] in a nutshell.

Anywho...The Problem.
I was minding my own business, listening to music and editing on a photoshop program, when suddenly my computer shut off on me. So, thinking that I might have accidentally pressed the power button with my leg, I restart it. Only to get a black screen with a little white flashing line at the top left corner of my screen.

I've heard people say to try to load it in Safe Mode. But I honestly don't know how to do that with Window's 7. I'm at a bit of a loss really. I've tried numerous things. I'm close to giving up...and so I'd really really REALLY appreciate any help given. I have a lot of files and etc...on this thing, and I really don't want to hear that there's nothing that can be done to retrieve them! :(

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.

Hello Nicole and welcome to Seven Forums.

Since you've already done a reinstall of Windows 7 and the problem has returned, I think I'd start looking at hardware issues. Perhaps a hard drive, RAM, motherboard, etc that's failing. One of the Forum experts has prepared a couple of troubleshooting guides that might help isolate the problem. I might start with the Memtest86 and HD Diagnostics test outlined in Steps 8 and 9, first tutorial.

Acer Travelmate 5542 turns on to a black screen with white line in the top left corner. I have changed all boot devices and still nothing works. will not boot t oCd drive USB or HDDProblem Started: Acer utility said the original hard drive was going bad and to back up all data. So i did. Then i went out and bought a new Toshiba 500gb HDD. I've installed probably 200 HDD into computers so i had no worries. I then went to boot to a USB drive with window 7 pro installed. However i couldnt get a boot menu to come up with F1-F12 and even ESC. So i then went into the BIOS and changed F12 to be the boot screen. ( Also while in the bios i was able to see the computer can see the new HDD and the Sandisk USB) So after i saved teh settings and restarted i was able to get the boot screen but when i select anything it goes to a black screen with a little white line in the upper left corner. I was able to remove the hard drive put it in a different computer and it worked fine to install Win 7. So i put it back into the laptop and still same problem. I cant boot to CD/DVD, USB, or HDD

I would like you to use the tutorial below to access the Command Prompt to rebuild the Boot Configuration Data.
 
The tutorial below includes a link to download a Windows 7 ISO image and instructions for burning this to a disc to create a bootable installation disc.  You will need to follow the instructions to step 7b, in the instructions there you would normally choose the Startup Repair from the System Recovery Options, but in this case you will choose Command Prompt.  You do not need to use these instruction any further than step 7b.  This will open the elevated command prompt, it will look similar to the image below.
 

 
Copy and paste the command below in the command prompt, then press Enter.
 
bootrec /rebuildbcd
 

Instructions for a Windows 7 Repair installation.
 
A Windows 7 Repair Installation will require a installation disc.
 
If you do not have a Windows 7 installation disc you can download a free legal ISO image of Windows 7 SP1 at  Windows 7 Forums.  You will need to download the same version of Windows 7 that you have installed,  This image is hosted by the Digital River store which is an official distribution partner of Microsoft.  This is a genuine untouched image which is safe to download.

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?

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!!

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.

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.

Hey I just went through something very similar. I found that my SATA cable connecting the hard drive to the motherboard had failed. I replaced it with a new SATA cable, and it booted right up. Try the cable first if you have one lying around, plus its a cheap solution. If you replace the cable and it still won't boot up, it might be your hard drive. Seeing as how your machine is that old, it could fail at any time.

Hi,

I have an issue with a white rectangular box appearing in the top left corner of my laptop screen.

It covers the icons behind it and renders them 'unclickable'.

Nothing happens if the box itself is clicked on.

It does not stay on top of other windows, just the desktop.

It appears after the laptop has been to sleep and on occasions, just seems to appear randomly.

I believe it may be a problem with Display Link drivers i use for a universal adapter for multiple monitors. I have asked around on display links forums but i am yet to find a solution (updated all drivers, uninstalled, re-installed, etc.), so i thought I would ask you guys if you have any ideas.

After i press no do not continue executing this script the rectangular screen stays in place and wont go anywhere, when i try to drag the screen across all i get is the Logitech logo.

I tried system recovery, antivirus scan, anti malware scan, and addware scan.

So I just got my new Dell studio xps 16" laptop on Saturday. I reinstalled using my own Windows 7 Ultimate 64bit disk and have had absolutely no problems.


However today, I noticed that there is a single bright white pixel in the top left corner of my screen exactly at the (0,0) position.

It seems to only show up on the desktop, because running pictures over the corner where it shows, it does not show up. I also have run several programs to check for dead pixels, and it does not show up.


I know it is not a dead pixel because it shows up in a screenshot which I have included.

My video card is the Radeon 4670 1GB.


I have found a few threads online where people have the same problems but none of them really gave any soloutions.


I have found that if I terminate the wdm.exe (Windows Desktop Manager) process it disappears. However, that stops my window peeking from working.



Another thing, it does not appear right after I log in, maybe about 10 seconds after windows has loaded.

Any ideas?

First backup any files you want off of the computer with an Ubuntu Live CD saving to an external USB HDD/Flash Drive.
If you have a Windows 7 DVD or Restore CD put that in the computer and choose your language and then Restore Your Computer.
If you do not have a disc, then you probably have a restore partition. Restart the computer on the logo screen when you see the message Press (Key) to Enter E-Recovery do so, this will restore your computer to Factory Defaults. Be sure to backup first.

When I turn on Lenovo thinkpad desktop it comes to the Gateway screen then to a black screen with the cursor at top left corner. F8 is not working - whether pressing intermittently or holding down so I can't get to safe mode. F2 was working ( set up menu ). But it has now quit working. When holding down F2 or F8 it just starts beeping. Where do I go from here?

Hello, my computer will freeze every 2 hours or so and I have to restart it by holding down on the power button.

Then when I restart it I get a black screen with white underscore in the top left corner. Or sometimes a screen that says no boot device available.

I can still start the computer by going to boot menu and choosing HD at the start of setup. But if I don't press f8 then my comp will not boot up.

I don't have a clue whats wrong with it. I had to reinstall vista but still the same problems. Please help.

This is my first time posting here. Please forgive my ignorance, as I'm super not tech-savvy at all.

I'm going to try to explain what's going on as best as I can to see if anyone can throw me a bone here.

I have a Dell Inspiron 531, about 4 years old, and it's worked just fine up until yesterday.

I plugged my Canon camera into the front USB port to grab some photos off of it, when my computer froze. I had to hold down the power button to get it to shut off.

I restarted, and found that after the Dell logo comes up, the screen goes black except for a white cursor that flashes in the upper right hand corner. This has been going on since last night.

The only two options it gives me appear during the Dell logo screen when I can hit either F12 for the boot menu or F2 for startup menu. Once the screen goes black and I see that cursor, key punching does nothing.

I'm not sure if this is worth mentioning but, at one point, I somehow found myself at a memory diagnostics menu and it ran and found no errors but then froze at 99%. I have no idea how I was able to do that, and I can't find it again.

Sorry if I left out any info. Anyone have an idea on what I can do to start troubleshooting?

Have you tried unplugging everything from the computer except for mouse and keyboard?

You may attempt a Startup Repair

Are you able to boot into safe mode? Safe Mode

If you have another computer, you can burn Memtest to a disk and run memory diagnostics.

English is not my native language, but hopefully I can explain this well enough despite not knowing the technical terms.

I have been googling like crazy trying to figure out what this can be, but to no avail. It started after the Windows 10 anniversary update and it might be related to either chrome cast or spotify, as after resetting laptop to factory settings I did not see this problem again initially until I started using these again. However, when the white square pops up can be completely unrelated to using these, and uninstalling Spotify did nothing.

The white square isn't always visible either, but is still there as a large unclickable area. If I right-click on it, a menu comes up that says back forward and reload, but clicking these does nothing. The only way to get rid of it is to restart, but it will come up again pretty soon. Any ideas?

My computer is about a year old now, built by me and my dad. Recently it's been having some issues though-- for a while I think it was over heating, causing it to reboot. At least I hope it was just overheating. One time when I booted up my computer it told me overclocking failed, which was odd because I hadn't messed with any of the settings (all still defaults).

But heres the major issue: If you boot it up, after the BIOS it'll give you a black screen with a blinking underscore up in the left corner. If you're quick enough you can get it to go into safe mode, etc. You can also choose which drive to boot from--- I found that it only gives you the black screen with certain drives. But, I did notice that its very slow when you have the "loading" screen for windows-- it'll slowly fade in and start loading, then it goes to a normal speed.

Specs:
IntelCore2CPU [email protected]
Nvidia 8800 GTS (640 MB)
4 GB RAM (although I can't use it all...)
Don't know much about my mobo except its a P5K

A:Black Screen + White Underscore in Upper Left Corner

I could be a memory issue. Try removing RAM one stick at a time and seeing if any of them are causing it. Then try them individually in each slot. It could be the motherboard if only one slot is faulty.

Hi, suggests it's not seeing your disk at all - nothing to boot from.

Check your connections, check your disk - e.g. using a live boot disk or connect it to another PC.

If you can manage to read it again, run chkdsk on it.

My laptop is a IBM Thinkpad T40, which i had to rebuild using parts from another T40
It has a 1.5 GHz Processor Intel, Centrino Mobile
512MB of RAM
A 40GB HDD
and Windows XP Pro Completely updated
Upon a rexent start up, after turning it off last night normally, it ceased functioning.
Now after the IBM Thinkpad start screen it merely displays a flashing white dash in the upper left corner. I have some files on there that hadn't been backed up. (I back up every Friday it died on a Thursday of all the rotten luck.) Suggestions about what i can do to get it working again?

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.
