Black Screen with white underscore in top left corner

Q: Black Screen with white underscore in top left corner

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.

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.)

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.

Nvidia 8800 GTS (640 MB)

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 guys,

The other day I was using my old desktop and using firefox when suddenly firefox froze up while browsing and I was unable to ctrl+alt+del or click start or anything for that matter in order to close it down. I then turned off my computer manually by pressing the power button as I sometimes do when my computer freezes and turned it back on. Unfortunately, when I turned it back on the computer is stuck on the black screen with the blinking underscore in the top left hand corner.

I unfortunately am not good with computers and would like to avoid reformatting my computer, as this old desktop contains the largest amount of my media such as music and movies that I had been meaning to put onto an external hard drive. Furthermore, I do not have an XP installation disc and am unable to locate the system recovery discs that came with the PC (like I said, it's old, circa 2006, and they are most likely lost somewhere in the house or thrown out by now). Thank you for all the help and support in advance.

if you haven't tried, as you switch on press the F8 key up and down repeatedly, if this works you will be at the safe mode menu - try last known good config. If still no go, try booting to BIOS - if this doesn't work I would say hard drive issue. Download the hard drive manufacturer's diagnostic program, this has to be burned to a disk. Then put the disk in and let it boot the pc and run the test.

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.

Other places i have found similar issues:
White box in desktop corner on Dynadock with Windo... - Toshiba Forums

I have attached a screenshot of the issue.

any help would be appreciated.

So I was running through westfall on my gnome mage (ALT) and bumped into a much lower level ripper, as usual frost nova and keep running! But my system crashed, couldn't alt + tab or clsoe the program. Rebooted my computer which I have own for approx 5 months and it reads the motherboard fine then goes onto this black screen with a white flashing underscore. IF you leave it long enough it moves to another screen within the bios asking you what state you want to boot windows up in. None of my keyboard buttons work on this page and when the timer runs from 30 to 0 instead of booting up it just crash's...

Once i got a step further and I was on the XP loading screen but it never loaded.

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?

Hi.
 
I have a problem with my computer that started about a month ago. The computer hadn't been used for about a month.
 
Most of the time, probably 19 out of 20 boots, my screen displays a black screen with a white underscore in the top left hand corner before i get to the BIOS. This is before any manufacturer logos appear. It is the usual flashing underscore which has obviously frozen.
 
I have re-seated all hard drives, my graphics card, removed all cables from my PSU and plugged them all back in again. Problem still existed.
I then unplugged all hard drives and tried to boot and the same problem happened again which rules out HDD failure.
 
It's going to be a problem with the PSU, graphics card or motherboard but i don't know which.
Before i start replacing parts, does anyone have any ideas on what it could be?
 
 
Like i said, it doesn't happen with every boot. Once the computer is on, it works perfectly. Putting the computer to sleep rather than shutting down has been working for a while which is how I've still been able to use the PC.

Hey guys, I've recently just built my own computer with the below specs:

Motherboard: ASUS P5QL-Pro
Graphics Card: Gigabyte 9600GT 1GB
Hard disk: Samsung 120GB (it's an old one I kept which I'm sure works fine)
CPU: Intel Q8200

OS: Vista Home Premium
Not overclocked whatsoever.

It appears that when I go out of my room for a few hours, when I get back, it shows a black screen with a white blinking underscore on the top left corner. It also appears almost everytime I turn on my PC. Pressing ALT-TAB-DEL will restart the PC, bringing it to the same black screen.

The only way I get in now is trying to boot it through the VISTA cd, and restart through there WITHOUT even changing any settings. Most of the time I'm lucky and I get in. VISTA says there's no error whatsoever when I click repair the PC and run the memory error detection thing (forgot the name).

Any help would be great as this is getting increasingly frustrating :-\

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?

Hello,

A few days ago I made a clean wipe on my Toshiba laptop, and installed Windows 7 Home Premium x86 as my OS. After installing the OS on my laptop, I proceeded to let windows update check for automatic updates and install them. After installing some updates, I clicked to have my computer reboot. After rebooting it showed the Toshiba screen with the F2, F12 options but after that it goes straight to a black screen with a white underscore. I pressed the power button to turn off then back on my computer and proceeded to press first F2 but it went back to the black screen with a white underscore, then restarted again pressing F12 went to the black screen again, restarted one more time pressing F8 for safe mode but nothing works. I've looked up on Google what to do, but couldn't find a defendant answer.

I hope someone can help me.

My computer literacy is not the best but I'll try to explane the problem to the best of my ability. The last time I was on my computer when it was working it said it needed to update Adobe Reader after the update was done it had to restart and on the next boot up the problem first started. The eMachine logo will show up then after that all I see is a black screen with a white underscore. I tried to use system recovery disks that I bout from eMachines but when I get to eMachines recovery management and run the factory restore it will get to the last point where it says ''updating system'' get to 21% then jumps to 100% says recovery is finished opens the CD tray, It dose not say whether or not to take the CD out so I have left the last CD in and taken it out when it gives me the ten second window telling me it will reboot. F11 dose nothing at all, most forms say to tap F11 to try starting it in safe mode but that dose not work. I removed the bios battery then put it back in, I've removed one RAM card at a time thinking one might be no good no difference or error message upon removing the RAM card(s). I've been told I might need a new Windows 7 Home Premium CD but I can't afford one, even if I could I would not buy one just save the money for a real computer such as a Dell. I have a functional HP laptop that uses Windows 7 Home Premium, is there a way to transfer files from that computer onto a flash drive then lode them onto my eMachine?

A:Black screen with white blinking underscore after eMachine logo.

So there are no error messages? Just a blank screen with a blinking cursor? The means the computer is looking for a disk to boot from and can't find one.
The fact that the repair disk didn't work indicates the problem could be the hard drive itself, and the problem will be hard to diagnose if you can't even get the computer to boot into safe mode. Transfering the files from another machine to the eMachine won't work.
In fact, you may have to do the opposite -- remove the hard drive, hook it up to another computer (an external hard drive dock with a USB connection is best for this), transfer over your important files, then place the hard drive back in the eMachine and try to reinstall the operating system. Then copy over the files from the other computer to your eMachine.

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 mot entirely sure if I used the right function.

Hi,
Yesterday I was playing a computer game, when my pc suddenly shut down, so I restarted and tried again, and the same thing happened.
So I figured the PC might be overheating, I told my dad, who got rid of the dust inside the PC.
But after putting all the cables back into the pc, when we tried to restart the computer, all it did was show bios information (American Megatrends etc) After that the computer continues, but after it says "checking NVRAM... update OK!" it goes to a black screen with a white blinking underscore on the top right of the screen. I can't see any sign of windows whatsoever (I have windows Vista). I tried getting to the safe mode, which I read about after googling. But I can't enter safe mode, all I get is a screen saying "Please select boot device" and it shows 4 options: 3 "USB: Generic Flash" options and 1 "IDE:HL-DT-ST DVDRAM" option. But whichever one I choose, it just goes back to the black screen... I read about this on google too, and people said you should close this screen and keep pressing F8, but when I do, nothing happens, all I see is the black screen.
Does anyone know what to do to fix the problem?

Hey guys I have a Song Vaio RBG-53 (I believe) with XP. I was using google images when I clicked on a picture and got a fake anti virus pop up. It wasn't the normal one I've seen quite a few times so I alt f4 closed it and immediately ran my AVG virus scan. That found nothing so I ran Malwarebytes which found 4 infected files. Two were in the registry and two were in my temporary internet files...I believe. Then I had it remove them and it said I needed to reboot to safely remove the files. I did that and when the computer started back up, it showed the initial Sony Vaio screen and then it goes straight into a black screen with a blinking cursor at the top left corner. The fan in my computer will run pretty loudly for about a minute and then slow back downto normal. At this point I'm not able to do anything. None of the F keys do anything. I tried ctrl alt del and that has no effect either. I can't get into safe mode or recovery console or anything like that. I've been researching google for the last hour on this and all the fixes involve just going into safe mode or using a repair cd, which I do not have. Does anyone have any other suggestions? Thanks.

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

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.

A:Vista with black screen and cursor in left corner

Look at your BIOS settings. The Acer screen may tell you how to access the BIOS (boot) settings with a function key - probably F2. Press that F2 or whatever it tells you when the Acer screen comes up. When the BIOS screen displays, make sure the "boot from" setting is your hard disk. If not, change it.

It's not booting to your Hard Drive. You can set the boot order in your BIOS. It is either F1, F2. Delete, F5, sometimes F10. HP usually uses F10, try that first.

Then set your boot order as follows:

CD/DVD first, Hard Drive second, then it does not matter after that.

Also, in your BIOS you will be able to see if your Hard Drive is being detected, if not, try unplugging the power and Data cables and plugging them back in, HP's are notorious for dropping the Hard Drive, you have to buy new SATA cables constantly. You may need to do this.

A:Black screen with flashing cursor in upper left corner of screen

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.

Do you get anything on the screen when you turn it on?

Hello , my computer won't start up to windows . I do not have the cd to restore my computer . I have a compaq windows xp computer . I believe it has to do something with a program called norton ghost that I was running , it froze so I restarted the computer and I chose to start windows normally . The blank screen then came up with the blinking cursor on the top left corner . Is there any possible way I can fix this problem myself ?

Norton Ghost is a Clone/Imaging software to clone your existing HDD to a different HDD. What exactly were you trying to do?

Boot off of the Windows Disc Or download the Recovery Console ISO. Burn it to CD with IMGBurn Boot off of the CD and get to the Recovery Console. Here type chkdsk /R and press enter. Disk Check Outside Windows (Windows XP) The Check Disk utility will try and fix any file errors.
You can also download the ISO image for Seatools, or DriveFitness in my signature and burn the image to a CD using IMGBurn also in my signature and boot off of the newly created CD and run the Quick and Advanced tests on the HDD to test the integrity of the drive.

My Acer has a black screen flashing mark upper left corner just after the opening screen, it just happened ,can I get some help thx ....

A:black screen flashing mark upper left corner

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.

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.

No issue.Hardware problem?Any advise is greatly appreciated.

A:Holding X240 by bottom left hand corner causes screen to black out and flicker

Hi, I had this problem several times as well. First time it happened was I picked up my x240 (with lid open) from the corner to the left of the trackpad, and the screen flickered and crashed. The x240 crashed the same way when I was using the x240 on my lap, while resting my left elbow to the left of the trackpad, supporting my chin reading the a document on the screen. I think the crash happens when there's pressure to the area to the left of the trackpad. It would be great if anyone else could replicate the same problem, and hopefully somone can find a fix!

So I have this white pixel on my top left corner... It's not a dead pixel, but it's there. Did not seem to notice it before, but I am sure it was not there when I got the laptop. I'm not sure what might have caused this. It rotates with the screen. A full screen app like chrome covers it, but it is very visible when on the desktop. It's not my wallpaper. When I hover over it, I get a loading cursor. Nothing happens when I left or right-click on it. Does anyone have this as well?

I need help urgently. I have my finals tomorrow for my AP english class and all my files were saved on this laptop. Everytime I boot my laptop, it does not go past the windows 7 loading screen. It just shows hp and press f11 for system recovery. The thing is, when I press f8, or f11 , to system recover or to go to safe mode, the laptop goes to the black screen with the blinking white cursor at the top left. I can enter the system diagnostics screen and I checked everything on there. It says the battery, all hard drive, and memory is ok. But I can't friggin system recover or get past the hp screen. Is there any commands or anything I can enter to factory reset the laptop? I can enter the command prompt screen because I have a disc, but the disc does not allow for factory reset. It only allows system restoring to an earlier date, and I've tried every single of the restore points. Each one still gave me the black screen with white cursor at top left.

If you recover you will lose your files. I would check that the hdd is seated properly

I had a "System error 32" on my PC screen and went search the internet for a solution. I found one that said to go to the windows folder and delete a file that had "warnhp in it". I did so, but now if have a white box in the upper left corner of the screen under a group of my icons. I can move the icons, but the bos remains.
When I right click on the box, and select "Properties", the file listed is file://C:\WINDOWS\warnhp.html
When I right click on the box and select source, it comes up with file titled C_WINDOWS_warnhp (1) -Notepad with the following info.

Hello,
 
I am new to this site. My computer seems to freeze often. Unfortunately, a freezing episode occurred during a windows update, so I turned off my computer even though it says "do not turn off your computer". Ever since I did this, when I try to turn on my computer, the BIOS loading bar goes to about 4/5 the way before it stops and goes into a black screen with a white cursor on the top left. I also cannot access safemode by repeatedly pressing F8. What is wrong with my computer?
 
Thank you.

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
