View 1 RepliesToday when I started my computer I logged in and after than I get a black screen with my cursor and desk bar flickering and can't do anything.

View 1 RepliesI installed windows 10 from 8.1 on my Vision E2 Gateway. When I sign in, the desktop keeps flashing a black screen every second. It doesn't allow me to open anything, I can't click on any icons visible, and this has been happening ever since I first signed in with windows 10. Is it a virus or something? It can't be that my computer isn't compatible, because it TOLD me it WAS.
View 1 RepliesThis is weird. I rebooted and the windows logo showed up but then it went to a flashing black and white screen. I rebooted a few times and the same thing.
Then I tried F8 while booting (thinking that would get me to safe mode) and it booted fine. BUT, it didn't look like it went to safe mode (not sure if it is obvious in Win10 since I haven't booted to safe mode yet). I rebooted a few more times and all OK.
I have downloaded and successful installed Windows 10 on one of my two computers. When I downloaded to second computer it hung on the installation re-boot. Now machine will only display BIOS splash screen and then shows a black screen with a single fast flashing cursor.
I tried putting the original Windows 7 install disk in the DVD but could not boot that way either. I can not get in contact with Windows support in Australia and have not been able to find an email address.
PC froze and wouldn't ctrl-alt-del, so I turned it off from the power supply, and when I turned it back on, I get a black screen with flashing cursor just after the BIOS splash and just before the Windows symbol would normally appear. I've used a recovery usb - refresh, automatic repair, and system restore do not work, and I can't continue booting with the usb, can't get to safe mode.
I had a spare SSD, so installed 8.1 on it and used it to boot the PC, then attached the drive that wouldn't boot as a secondary drive. All of my files/programs appear to be there on the faulty drive, but for whatever reason the Windows 10 installed on it will not boot.
I'm sure the easiest option would be to wipe the trouble drive and reinstall Windows, but there are several work programs that would be a pain to go back and reinstall (would have to call in the vendor). Since the drive itself seems to be working, could I create a new partition and reinstall Windows to it, then uninstall the corrupted version?
Recently I've started to encounter an error when booting my computer, occasionally it would boot to a weird flashing white and black screen. An example of this can be seen here: [URL]....
This occurs just before the login screen. While this happens, my cursor is still visible, though larger than normal. After a while, the flashing stops and the screen stays black, usually before this I would force restart my PC then it would boot fine.

When I turn on my laptop, it shows a black screen with non-flashing dash on top left after Lenovo logo. I did the clean install but it didn't work. After that,I tried to clean install Windows 10 on my old HDD and it works! Why my SSD isn't work?
P.S. It can enter the BIOS menu
What does it mean when you see a black screen that has a grey flashing dash located at the top left-hand corner of the screen? It moves down a bit before finally moving onto the Windows 10 logo, where it sometimes gets stuck and reboots (and the grey dash screen appears again before moving on).
I noticed this issue both during upgrade (when it failed and tried to recover the installation) and after installation. This issue occurred on an Acer Aspire Z5801. It does not occur on Windows 7.
So I have a bit of a problem where my screen flashes, I instantly thought it was display drivers so I uninstalled them only to worsen the problem, the computer restarted with a black screen which later turned into a desktop screen with no icons and a flashing screen (can't click anything or even load up the start menu with the windows key). I put it into safe mode but it does the same thing. Nothing works except task manager and i can't run task from it or it will exit out, system restore doesn't fix the issue either. Computer is a lenovo k450 i5-4440 8gb ram 1tb hdd with an evga gtx 760.
View 1 RepliesAbout a minute after starting up, my desktop begins to start flashing to black and coming back in a continuous loop. The file explorer, however is completely unaffected. Using Google I have found that this occurred back in the technical previews of Windows 10 as well, but a new update from Windows fixed the issue. I can not get the explorer stable long enough to even check Windows Update. I have also run sfc /scannow and it said the integrity of my system is fine.
View 4 RepliesI upgraded to Win 10 on Friday, and since, despite several resetting PC attempts, Win 10 will not load to the login screen. Instead, it is stuck on a loop flashing between the lock screen and a gray loading screen quickly back to the lock screen -- instead of loading to the login screen. This only happens when I attempt to restart or update my PC. If I go to the lock screen because I locked my PC or it fell asleep, I can unlock it. I have also attempted to reset my PC to the previous build, to no avail. I have no restore points.
View 1 RepliesI have a Lenovo flex 2 laptop that is brand new and used to run windows 8.1 until earlier today.
I opted for the recommended win 10 upgrade, and things went smoothly until it was time to reboot.
The laptop begins to boot, I get to see the Lenovo start screen for a few seconds, and then it turns off before starting over again.
This loop has been going on for 8 hours, as of right now.
All attempts to access the boot menu via the F2, F8, F11, and F12 keys have failed, and the novo key has had no effect.
I am desperate at this point- the laptop is brand new. And now it is next to useless. No actual customer support is available in the country I live in. I just want a way to go back to win8.1.
I upgraded from Windows 8 to 10 without a hitch an hour ago and kept all of my personal files and apps. I set up my start menu and everything was working fine, but I wanted to change the image on the logon screen (or whatever you call the screen in between the lock screen and the screen where you enter your PIN/info). So I took a risk and downloaded the 3rd party app here:
[URL] and uploaded an image and hit apply. Of course right after doing that I went to lock my PC to see if it worked, and as you can tell... it didn't.
I've tried rebooting and it hasn't worked. It's just very rapidly flashing between a blue screen w/ a loading circle and my lock screen image.
I cannot explain exactly the problem so i made a video.. here : [URL] .... I tried disabling the 2 services from msconfig..but no luck..

View 1 RepliesI installed windows 10 on my machine last week which went fine with no errors. Since then, I have come into work everyday and found the computer idling at the login screen, flashing and not responding. Just a constant flashing until I turn it off. Because of this I've had to reset windows under the troubleshoot option on start up. Safe mode doesn't work, and back up restore doesn't either. I wanted to add that I don't receive an error code or message.

View 1 RepliesProblem with the logon screen with windows 10. I upgraded on the morning of Saturday 8th August, without any serious problems. However, later on in the afternoon, I had to do a restart, after a virus/malware scan and removal of infections. The OS was updated at this point, after which a serious problem occurred. Once the OS reached the logon screen, it started flashing on and off between Logon screen and time/date start up picture, with the cursor showing busy. It also reported an error message to do with LogonUI .
I had no way to Logon, or to open task manager, so i had to boot into safe mode, and attempt various problem solving solutions read elsewhere for this issue on the net. None of these worked, so i had to roll back to Windows 7 for the time being. Should i upgrade again, this issue will have to be resolved.
Finally, though, i'm led to believe that LogonUI is malware, and not an important system file, but should it be removed, would this be the cause of the issue?
Flashing screen on new Windows 10 install. I figured out how to return to Windows 8.1. It's restoring on my notebook as I typing this question on my Desktop. I Googled 'flashing screen' and it seems to be a common occurrence.
View 2 RepliesI tried upgrading last august from windows 7 and encountered the dreaded flashing screen. it was not all that easy to revert to windows 7 with a minimally unresponsive computer but i managed to do it. Question - Has this issue been resolved and will I encounter the same problem again if I try the upgrade again? Windows 7 is working fine on my desktop HP and I really don't want to deal with the hassle again.

View 1 RepliesMy computer has always been fine, until one day i was getting pop ups and redirected randomly, i notice a strange file called "techsmart computer" and was trying to delete it but couldn't so i wanted to go into safe mode and forcibly remove it, i open the start up menu simply check safe mode only and restarted, ever since all i see is the black screen with it loading with nothing else no repair, error message just it loading then it goes to the login screen the blue one and for some strange reason it is flickering as it its turning on/off and its a never ending load! if i press the power button its shutting down and it stops flickering, i searched online for solutions and nothing relevant and of the possible solutions i cant do because i can never get into the login screen, this is not a instillation issue or driver or graphics card, etc... started ever since i checked the safe mode, i want to mention i'm writing this using a different computer, also don't know if its a 32 or 64 bit.
