Black Screen Appearing After Log In Screen

Feb 10, 2013

Computer will turn on and go through the motions of start up, but when the log in screen should come up it black screens on me. It doesn't shut off though...? Just goes black. So beyond that I can't even get in to tell you what is wrong and I can't get the pop up back that said what the problem was.

Windows 7 Black Screen Appearing Withing A Minute Of Start Up?

Mar 11, 2012

My promblem is, I shut down my computer earlier in the afternoon yesterday. I come back and turn it on and after running a minute or two, the fans are going like crazy and screen goes black, monitor goes to sleep. I manually hold down the power button, restart and choose the option to repair. Once again, after a minute or so fans start running hard, blacked out screen, monitor goes to sleep.My husband has tried F8 and we've tried going back to a restore point. It will start and sound normal, but when the fans start to run hard we know the screen will go black.Opinions from various people I know and from websites are stating it's my ATI Radeon graphics card. We've even tested the RAM, yet within those two minutes after start up, monitor goes black and states no signal or it's sleeping. We've also tried numerous monitors, just for sake of process of elimination.

When Reboot, The Screen Eventually Goes To A Black Screen Saying "Windows 7 Failed To Start?

May 12, 2012

My wife did something on her PC (she doesn't know exactly for sure what & can't explain it completely me), and now she can't boot up her PC. She says it had something to do with changing the security settings for a program she uses a lot so it wouldn't keep asking her if she wanted to launch it, and that's when it told her to restart the PC, then it wouldn't boot up anymore.When you reboot, the screen eventually goes to a black screen saying "Windows failed to start. A software or hardware error may be the cause" or something to that effect. It offers me the option to "Launch Startup Repair" or "Start Windows Normally".If I Launch Startup Repair, nothing much happens --- it says it's adding files, then it looks like Windows is about to boot up, then it goes to a black screen for a long time & nothing happens.

If I choose Start Windows Normally, it simply reboots & eventually brings me back to the same screen again.I've tried using rebooting and selecting ESC to get to the boot menu, then installing the Win 7 installation disc & selecting the DVD drive, then I select thelanguage, then I click Repair, but it sits there forever with nothing happening.I also tried an outside boot disc I found on the web & it doesn't launch.

Dell Vostro 1520 Black Screen Won't Reach Login Screen

Dec 15, 2011

i have a Dell Vostro 1520 and im running Windows 7 with a 32bit. It is only 2 years only. It started about a month ago. I was on my laptop viewing and deleting some unwanted photos i had. A few minutes later i realized that i deleted a photo that i wanted. So i went to the recycling bin and restored that photo. When i went back to my photos and went into the album, it said something like i do no have permission to access this folder. Please press continue to get full permission. I clicked continue and i got the access i should have. Now i tried many more random folders and the same thing happened. Also when i came out of the folders, the folders had a big pad lock sign on the front of it. After that i shut down the laptop and went to turn it back on. The laptop will power on like normal. I can press f12 for the boot options. which i have already tried many times. I also tried it in safe mode and what-not, but still nothing. I can hear the fan and stuff spinning up like normal. I have also put and CD into the CD ROM and that spins up fine. So after the Dell logo on the screen, it goes black and stays that way with the cursor. You can move the cursor around no problem. I should also add that the battery light is and has been flashing for a good wile. Its flashing orange and blue. I'm wondering if this has anything to do with the battery. Because my laptop will not charge with the AC adapter in it for many months now. It will only stay powered on with the AC adapter plugged in. One more thing. The LED lights over the buttons. None of the are flashing, besides one, on the far left. And i cant find out anywhere what this LED light stands for.

System Goes To Black Screen Before Login/welcome Screen After Windows 7 32-bit Upgrade?

Sep 2, 2012

My son has a Toshiba Satelite P205 that he just upgraded from Windows XP Home Premium to Windows 7 32-bit. After the upgrade completed the computer booted fine. The within 20 minutes he got the BSOD and the system rebooted. Now he can't get Windows to fully start. We've tried all of the options from F8 with no success. We have the Toshiba System Recovery Disk but it won't launch. (The Boot sequence has been changed to boot from CD/DVD and then the Hard Drive.)The Memory Diagnostic from the Windows 7 disk ran fine with no errors. I'm thinking I might need to re-format/wipe the drive to start fresh but don't know where to obtain a boot CD(no floppy drive on this laptop). Does anyone recommend a software that I can purchase to clear everything without destroying the CD/DVD accessibility so I can then use the System Recovery Disk to put it back to the original factory Settings?

Full Screen Videos Crashing To Black Screen And Buzzing

Mar 26, 2011

My computer has a problem with crashing while playing a video in full screen. When it crashes the screen turns black while the speakers give out a buzzing noise. Everything is unresposive the only solution is to turn it off with the power button. It happens in any full screen video online or offline and even visualizations from windows media player and iTunes, but only in full screen. I don't think it's overheating either because sometimes it takes 30 mins to crash and other times it will crash immediately when put in full screen. *I've tried setting it back to factory settings thus reinstalling windows. *All the directx features are working with no reported problem there.* I don't think it's a memory issue in the computer, as my specs are:

Windows 7 64-bit
Processor: intel core i5 3.20 GHz
Ram: 8 GB
Graphics card: NVIDIA GeForce GT 220
Graphics card memory: 0.5 GB
Any other ideas?

I've only had the laptop a year.

I just upgraded to Windows 7 on my Toshiba Satellite Special Edition laptop that came with Vista 64bit and the other night i downloaded iTunes 10 and told me to restart my machine so I clicked ok and then my laptop shut off and when it came back on the Toshiba screen came up as usual but seemed to stay on longer than normal then it goes to a black screen with a underscore that blinks for a few moments then becomes solid.

'Resuming Windows' Screen Where Everything Turns Off And Screen Goes Black

May 25, 2011

I have recently bought a computer and I have found that when I turn it on it runs normally until after the "Resuming Windows" screen, where everything turns off and the screen goes black. It had been running well for the last few days, so this came out of nowhere.I have searched this problem and I come up with a bunch of different solutions but no one agrees. The most common reason (apparently) is my version of Windows 7 Home Premium (x64) and I need to install something or other. But I can't even get to the desktop, and no one really explains it simply.

Black Screen Of Death During Boot, Before Login Screen

Mar 18, 2012

While attempting to restore a previous backup of my system (with Norton Ghost 15), I got an error, and the system rebooted. Upon reboot, I get the black screen of death with just the cursor instead of the usual login screen. I have tried the following thus far: These all give me the black screen of death with movable cursor:boot in safe mode boot in safe mode with networking boot in safe mode with command prompt last known good configuration I did an initial system startup repair which went through and said it repaired it, rebooted, but no change. I did a pre-boot diagnostic test - nothing memory test - nothing tried restoring from restore point, but it says I don't have any (LIES! BLASPHEMY!) tried restoring from restore point on external disk - seemed okay, then failed. chkdsk - found some stuff, fixed it, no change. tried ctrl+alt+del on black screen of death - nothing

Now, I know that the hard drive itself is alright, that is, the information is still all there still. While I can't give you exact specs, I can tell you that I am on a Dell Studio XPS running Windows 7 home premium 64 bit. I'm at a loss as to what else to do. Despite being a black screen, with just a movable cursor, the system still appears to be running, as every few minutes, it will show the "thinking" cursor, where it shows the little circle next to the arrow.

Black Screen W/ Cursor After Windows 7 Loading Screen?

Mar 24, 2012

Recently, my computer starts up windows and after the loading screen it just sits at a black screen forever with a cursor and it doesn't even make it to the log in screen. I have tried safe mode with the same results. What I've Done So FarTried to Repair Startup with Windows DVD Tried to use sfc /scannow at boot (Says pending changes and needs to restart) Tried logging into my Ubuntu partition and virus scanning (None found) Tried copying Reg Files from Regback into config while I was in Linux Tried to Repair Install (But I can't log into Windows ) Tried to bootrec /fixmbr /fixbot /RebuildBcd (Which destroyed my dual boot linux grub, but I was desperate. And still nothing) Interestingly though, after I do /RebuildBcd command it says something like "Found Windows Installations: 0" Tried to System Restore (Gave me an Error, wouldn't you know) At this point I'm not to confident that this can be fixed. If anyone has any ideas I'm willing to try. Or if you have any snazzy suggestions on how I could fix it using another computer, I have a different Windows Pro x64 computer that I can put the HD in if there's someway I can save my data/fix it/repair install from there. I just don't know how.

Edit: I finished the chkdsk and there were no bad sectors, though it did give me a message "Failed to transfer logged messages to the event log with status 50."I did a Windows Defender Offline scan with no viruses and I'm currently scanning with Kaspersky Rescue disk. I don't believe it is a virus, I think it's a corruptregistry at this point. I had just cleaned my registry with CCleaner before the shutdown that led to this >.<

Black Screen, Screen Only Works In Safe Mode?

Aug 8, 2011

i have an HP Pavillion dv7 with windows7. It is less then 3 months old. Problem- Yesterday the screen went black while i was watching a video, but the sound kept going. so i restarted the computer, and the screen works until you get to the login screen it goes black again. SO i called customer service at hp, and we worked on it for an hour.THe one thing that seems to work is when i go to the device manager, uninstall the display adapters, and restsart in normal mode, then i go and reinstall the ATI device thing in the recovery manager, but everytime after i reinstall the ATI display device thing, it ends up going black a little while later again. lol

Login Screen Is Not Appearing?

Feb 3, 2011

When I boot up my computer, it displays the animated windows7 logo as normal, but where it would normally display the login screen all I get is a blank screen with the mouse cursor. I've tried all keyboard shortcuts and random clicks to no avail - it stays on that screen for hours with occasional HDD activity.I've tried booting in safe mode only to encounter exactly the same problem, and have no previous restore points (which I know is a big mistake).Due to it not starting in safe mode either, I tried to replace the winlogon.exe file from another Windows 7 instillation to no avail - I still get the same problem.I am able to boot into linux (off my removable HDD) and windows XP (from my secondary internal HDD), so I am led to believe it is a corrupted file or dodgy setting within Windows 7 rather than a hardware fault.

Black Screen After Windows 7 Load Screen?

Dec 8, 2012

Whenever the Windows loadscreen passes the screen goes black and I can move a cursor around the screen. I have had this happen before and fixed it with bootrec.exe but I can't seem to get that to work this time. Safe mode has the exact same black screen problem.I have done chkdsk and sfc scannow - Didn't fix it.When I boot into Kaspersky Rescue from a USB drive it mentions that I need to shut down windows properly before continuing. I would like to do this but I can't.I have tried changing the active partition on information in some of these other threads - It didn't seem to work.All disks are healthy according to the DISKPART and Partition Wizard. I have done the HP hardware diagnostic scans and everything comes up fine.

Black Screen BEFORE Post Screen On Restart?

Dec 22, 2012

Just purchased 2 new (refurb) PC's for my wife and I. It's all I could find with Windows 7 still available. They are both HP Pavilion p7-1233w 64 bit Desktops running Win 7 Home Premium SP1.During Windows setup of PC #1, it asked for a restart. When the PC powered back up, it had a black screen from the start (before the Post screen). I power cycled it several times with no luck. Even switched monitors and video cables. The next morning it started normally with perfect video.I assumed the Refurb PC had a problem and set it aside for return.Been setting up PC #2 for a few days now with lots of restarts. All was well, until I did a restart just now. There was the identical problem. Power cycled the unit twice, and still had the black screen.Then I unplugged the PC, and pressed the power button to discharge the capacitors (fans ran for a few seconds). When I returned power and started the PC again, it functioned normally. I've done 10 quick restarts since to try and replicate the problem, but it only happened that once.

I love these PC's, and I love Win 7, so I hate to give them up. But I don't want the video freezing up on me every time I do a restart. I assume now, that PC #1 is not necessarily defective.Since this is occurring before the post screen, I wasn't sure if it could be windows related.

Black Screen With A Cursor, Login Screen Won't Appear

Oct 4, 2012

I got a bad virus on my computer about a week ago. I decided to use my windows 7 installation disc to reformat my disk drives and reinstall windows 7. The installation goes smoothly and I am able to login to windows. But after I install drivers and updates, then restart the computer, I get the "starting windows" screen with the swirling logo. I can hear the chimes that sound when I get to the login screen, but the screen is black. I can make the cursor appear by moving the mouse, but I cant do anything else. I never created a system restore disc, so I dont have that to help me.I have done some tinkering and will tell you what did not work so far.First, like I said, I used the windows 7 install disc to reformat my disk drives. Then, I reinstalled windows. I installed the updates for my graphics card and motherboard. When I restarted, I got the black screen. I restarted the computer and used F8 to do a system repair. This detects no problems. I tried to use the "startup repair" on the windows installation disc. This does not recognize a problem. I have tried it several times. Same result. Next, I tried to use the repair options on the windows install disc. I went to command prompt and typed in: bootrec.exe /fixmbr, bootrec.exe /fixboot, and bootrec.exe /RebuildBcd. (An interesing note: When I used the RebuildBcd command, it said that it detected 0 windows installations.) After the first time I did that, I tried the startup repair and got my first and only error message: "Startup repair cannot repair this computer automaticaly". I checked the details and it said "Problem event name: StartupRepairOffline". If you need the rest of the details, I can provide them. But I tried the repair again, and there was apparently no problem. Yet, still got the black screen.I then reformatted again, deleted both drives, and made new ones. I tried to install windows again, and I can get to my desktop.(One thing I noticed is that before I install updates, the computer is saying that my monitor is a "Generic PnP monitor on standard VGA graphics adapter". I dont know much about computers so this may be normal before installing the graphics card updates.)This time, I was connected to the internet and tried to install the system updates first. After all 120+ updates installed, I restarted and got the black screen again.I decided to use the install disc again to reformat, delete, and recreate the hard drives. This time I tried to install windows on the second hard drive (Disk 1) Again, the install went smoothly. I started installing the graphics card and motherboard drivers, but this time it told me that my disk drive D needed to be formatted before use. I reformatted it (this took MUCH longer than the format option on the install disc), installed the drivers, and restarted. I still cant get into the login screen. Finally, I used the install disc to reformat, delete, and recreate the disk drives. This time I installed windows on the first hard drive (drive 0) again and got to the desktop. Now I tried to install the motherboard drivers first, then restart. I did this and was able to restart and get back to the desktop. Next, I installed the graphics card dirvers, and then restarted. Black screen again.

Here are my computer specs:

Windows 7 64bit OEM
EVGA P55 FTW motherboard
EVGA GTX570 graphics card
Intel i5-760 processor
Intel patriot 8gb ram

Lines Appearing On Screen When Using VGA But Not When Using HDMI?

Feb 6, 2012

I recently made a thread on this forum talking about how my new PC setup has suddenly started creating lines on my screen

Link: Wavy lines across screen, (usually grey-ish colours) on new setup.

After trying a full list of things; 2 different monitors 2 different VGA cables 3 different mice 3 different keyboards change power supply change graphics card used onboard graphics switched ram sticks and removed one at a time reformatted a dozen of times unplugged all sound from computer checked motherboard for any visual problems and couldn't see any updated all drivers I could possibly think of Ran Memtest for 7 passes with no errors I've finally found out the problem and that was when I connected my graphics card using HDMI to a HDMI compatable monitor it worked fine and I had no more lines!

So it seems that using HDMI is working fine but soon as I use a VGA cable its not working and the lines are back. It only confused me more when I connected a VGA cable from another computer to the monitor it all worked fine.

As far as I can tell it's something to do with my computers VGA/HDMI settings, I've tried onboard VGA and that still didn't work so it doesn't seem to be a graphics card problem just something is stopping VGA working properly but HDMI is working.

I'm gonna have to go buy an expensive new monitor with HDMI compatability.
