Blinking Screen
May 3, 2009
Well, I think we might have a new one, I looked back a few pages in the whole list of topics.
My wife's computer is using a fresh install of Windows 7 build 7000.
This problem seems to happen randomly and we cant find a rhyme or reason to it. At first I thought it might be a heat issue, perhaps with the video card. Well about 4 months back(the blinking problem was not present at this time), I found her video card's fan had stopped working and we replaced the card with a new nVidia 9600GT.
The blinking started maybe a week or two ago.
Rebooting the computer does not help in most cases.
Placing my monitor on her computer was inconclusive. It did not blink.
Placing her monitor on my computer was also inconclusive. It did not blink.
Right now she is using a driver that is dated 4/2/2009. We are currently downloading the driver for 4/30/2009 hoping this will help, and once it is downloaded and installed, I will write back on my findings. Maybe we should update to the latest build of 7?
If I'm in the wrong forum, or location or if I missed a post regarding this same issue, please let me know so we can get this figured out on our end.

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. Ive tried to use the "F" keys to get different boot options because i have the windows 7 ISO disc and a ubuntu disc that I could use but whatever i try my laptop wont process it just does the same thing over and over again and bever proceeds to the actually boot up windows.

Almost every time I click (Open windows, maximizing windows etc, etc...) The whole screen will blink and I will see a brief (Not Responding) which only lasts for a split second, then I can resume my work, in the worst of cases this can happen 9 or 10 times until the computer actually responds and selects what I want it to.I have recently upgraded my graphics from a ATI Radeon X1200 (Old and useless) To a NVIDIA GeForce 7300 SE/7200 GS. ALL of my drivers are up-to-date and a system restore is not an option.

I have been using my emachines netbook 350 for a year now and running windows7 in it since I bought. A month ago, I've started seeing those blinking horizontal lines on my screen. Almost half of my screen is affected. I wonder if it is a problem with my video card or just some viruses. Well when I print screen, the lines are not showing. The same as when I connect my netbook to a projector

i have a lenovo thinkpad edge 14" running 64-bit windows 7 home premium. the laptop didn't come with any CD's, everything was pre-loaded on. all i get when i boot it is a black screen with a blinking cursor , when it boots all it shows is the thinkpad splash screen then straight to the blinking cursor. i have access to a lenovo x220 running the same (i.e. 64-bit Windows 7 home premium) however no CD drive, the edge 14" does have a cd drive. looked at multiple articles on seven forums but none of them help because i dont have a cd burner

I just installed the latest nvidia driver and bios in my XPS M1330 with windows.7. It worked fine but after two days, the screen blinking and glitching. I have to boot into safe mode and roll back to "standard VGA graphics Adapter driver" and it work fine.
so my question, is it dell until now no solution for XPS M1330 Graphic GPU problems? or any solution for this? i just want to connect my window 7 to projector. or any suggestion to connect to projector with standard VGA graphic adapter driver?
OS: Windows. 7 ultimate 32bit
graphic: nvidia geforce 8400 M GS
driver: v191.07 Windows 7/Vista 32bit | NVIDIA - NVISION
bios: A15
I tried all the driver in forums.laptopvideo each with driver sweeper to clean up the previous graphic driver but no luck. Anyone know how to connect the projector with simple driver or with 'standard vga graphic adapter' driver?

Ok I am at my wits end with this computer. I am trying to do a clean install of Windows 7 from a thumb drive, I have used this thumb drive for several successful installs, including one after my issue just to make sure it wasn't corrupt.
PC details Foxconn A74ML-k Motherboard with a Dual Core Amd proccessor, sorry cant find the model off hand. using on board graphics card, and a Western Digital WD6401AALS hard drive and 2 gigs of gskill ram.
This PC was running windows vista just fine before I attempted to Install Windows 7, I have tried to install Windows twice, once with the usb drive and once with a dvd disc both end results are the same. The install will go perfectly smooth, all the way til the final reboot. Once the actual install is complete when it try to first boot all I get is a black screen with a blinking cursor, I cant seem to enter safe mode.
I have searched and while it seems many have run into similar issues is usually due to things such as dual monitor set ups etc. All I have connected is a mouse, monitor, and keyboard. Microsoft lists the motherboard as compatible, I have reset the bios, tried a different hard drive, ubuntu live works just fine, the file system is there. I even pulled the hard drive out of my laptop and plugged it into the pc and I get the same result. Also I tried windows start up repair from the discs, it found no issues.

I recently dualbooted Linux Mint and Windows 7 on my laptop. Yesterday I removed the Linux partition without thinking, and forgetting about the GRUB bootloader. I'm at a stump now. When I try and turn on my computer, the Toshiba logo appears, then the screen goes blank with a blinking cursor. I searched the internet all of today and most of yesterday, all that did was tell me to do the bootsect /nt670 /fixmbr and all it's variations[CODE]

I have a problem, a small 1 i hope: i can' t seem to login normally into windows, i end up getting stuck at a blinking login screen with the message "please wait". When i try booting through safe mode it is successful. I have no restore point to fall back 2. All i did was uninstall a windows clear theme, prior to this event i could not install any .themepack file as it ends up displaying "could not find the msstyles folder". Is there a way around this predicament of mine or do i have 2 format my hard disk?

I restored my computer successfully but I still got the blinking cd icon next to my mouse pointer. After I restarted my computer I got Windows 7 with a clock and "2 min" under it and then it went to a black screen with blinking cd icon. I don't understand what is going on. I can get into task manager and type in explorer.exe but that doesn't do anything. I also tried the Regedit fix, but that didnt do anything too. I need help on how to fix this. My CD Rom won't even open for some reason.

My computer would not get past the start up screen � it just froze at the Windows 7 logo. Prior to this, I had absolutely no problems. I shut it down one night and came to start it the next morning and it wouldn't load. I format the drive and tried to reinstall Windows 7. It seemed to load everything fine and got to the "Completing Install" part, then just flicked to a completely black screen with a blinking line in the top left-hand corner.I did read on one forum that perhaps it was a RAM issue, so I removed one stick and the process actually completed! I thought I had nailed it. After setting my computer back up and with everything working just fine, I put the RAM back in. On restart, it locked at the logo again, so I figured it was definitely bad RAM, HOWEVER!! Even with the RAM now removed, I cannot get Windows 7 to reinstall. I am still getting this awful black screen with a blinking cursor.

I'm trying to boot up this HP laptop that shows a black screen with a blinking cursor after the HP logo. I've tried using a windows 7 recovery disc to repair start up.I've restored the computer to an earlier date that it was working correctly. I've ran every test in the computer's built in diagnostics, and every single one has passed, and no errors in any part of the system were reported. Also, the computer will not start up in safe mode or anything like that.

I have a Sony Vaio laptop with an upgrade to windows 7 from vista. Yesterday my computer was really slow so I reset it to try and speed it up. I got passed the Vaio screen but then came the black screen with the blinking dash on the top right corner. The only thing I can enter is BIOS with F2 nothing else works. I can't enter safe mode or anything else. I've tried a few things, but nothing works.
1. Reseting default values in BIOS
2. Removing everything but internal Hard Drive in boot menu.
I have a windows & start up disc
3. Ran Startup Repair: Says couldn't detect a problem if recently attached device then remove it. ( Nothings Connected)
4. System restore ( was successfull but still no go)
5. Ran chkdsk & chkdsk/r from command prompt option
I also contacted Sony Support and with the 15 minutes alotted
6. Reseated memory
I just want to be able to get into the computer one more time so I can transfer my music and some other important files to my External Hard Drive.

for some reason I can't even get into windows 7, after I get pass the screen that says "asus" , my laptop brand, It goes into a black screen with a blinking cursor in the left hand corner like this:
I'm unable to do anything at that point, it just blinks. I can't even boot into safe mode now, the only think I'm able to get into is the Bios Setup Utility menus and Asus' express gate, which is just a media/internet/gaming/skype thing that doesn't allow .exe files to run...
This came factory installed so I don't have a windows 7 disc to help run fixes or anything.

I was installing Windows 7 onto my laptop (previously vista) and install seemed to run smoothly (went past asking about. PC name, network etc) but after it said it was preparing for first startup, nothing boots. After restarting.. besides the startup Acer screen, there is only a black screen with a blinking underscore at the top left. Whats happening :S?
I've tried F2 and running a setup but it just shows me some specs and such
Btw it has 2.0 Ghz + 2GB ram x__x

Ok so recently I got a black screen with a blinking cursor on the top left. The computer starts up normally with the toshiba logo but then it goes to this black screen with a blinking cursor. I tried almost everything. I tried doing system startup repair, /fixboot /fixmbr, The "0" key, F8 doesnt work and so forth.I cant even reinstall windows 7 onto the computer because after it restarts to finish the installation it just goes back to the black screen with the blinking cursor on the top left. The computer is a Toshiba Satellite A205 - S5825 windows 7 32 bit.

Tech-savvy superior beings, I humbly come before you because my rig is having a fit. Whenever I start her up, I get as far as the splashscreen that reminds me which mobo I have, followed by a cursor blinking on a black field for eternity.
[code]...
Lovingly jumbled together based on my perusal of this very site. It has brought me much happiness until now. A thousand pardons if this problem has been resolved in another thread. I have been forced to look for solutions on a smart phone, which is trying my patience

I'm having regarding my Dell with Windows 7 x64. Initially I got the message "Loading PBR for descriptor 2... Done". That's all it said, and did not continue to boot. I researched the error message and found many users with similar problems that solved it by booting the Windows 7 dvd and running bootrec.exe from the command prompt, so I attempted this. I tried bootrec with the /fixmbr, /fixboot, and /rebuildbcd options. After trying to fix my problem with bootrec, the "loading pbr" message no longer appears, all I get is a blank screen with a blinking cursor after the BIOS. I'm not sure what the problem or solution is at this point. I'm not sure if I've made things better or worse. I tried running chkdsk /r but it won't run, complaining that the disk is write protected. Edit: I just realized that System Recovery Options is showing "Operating system: Unknown on (Unknown) Local Disk"

I have a gateway computer that is infected with a virus. I was able to load the computer in safe mode a couple of times before it no longer loaded login screen for my computer. Now when I cut the computer on there is only a black screen with a white blinking cursor. I have the avira rescue cd and have changed the seetings to boot straight from the cd rom but even after running the rescue disc the computer will not allow me to use the (f) function keys. When I press down on any of the (f) function keys there is a beeping sound but no action. I tried to use a windows reboot cd made from another computer but it does not load on the start up like the avira resue disk does.

I have a dell pc with windows 7. The computer loads the dell logo, the screen is black with the blinking line in the corner. I have tried all solutions that I have come across, the fixboot, replacing config files and last resort, I did a fresh install of windows. After the fresh install of windows, it worked for a few days and now it is doing it again. What is my next option?

Sometimes when I turn on my computer, the screen will turn on as usual, and there is like a cursor that blinks in the top left corner of the screen, again, as usual. However, it will sometimes stop, and stay on this screen for upwards of a minute or more. The laptop sounds like it's still working, as the fan is going pretty fast and everything sounds like it's spinning, however it doesn't show anything on the screen. After around the minute duration, the screen will go black and the normal boot up process is proceeded with. From what I've read of other people, they can't even get past this screen, which is why I think my problem is slightly different, or the same, just not as severe. Does my problem also sound like it's the MBR, as indicated by other people's questions on the Internet?
If so, is there any easy way to repair it without having to use a windows 7 disc, as I have a laptop and didn't get a disc with it...

So, Im doing a clean windows 7 install. Here are the facts: [code] After the final stage of the setup where you enter PC name, set the password, enter time settings etc, the setup restarts the computer for the 'final' time, final indeed.What happens is that after the Bios / device scan, Windows won't boot and it won't continue past the black screen with the white blinking _ showing in the top left.Could this be because C: has been 'occupied' (or set as master partition) by the 1480GB partition and won't boot from the 105GB partition where Windows was installed?It's so weird because the first two reboots go without problem, no need to F8 and manually select the disk rather than the USB pen or anything.. But on the final reboot, nothing.
