I have Windows 8.1 installed on my Toshiba Satellite C655D-S5531 Laptop.
I have had this issue for a while now, but never really thought about it.
Every time I log in on my account (and ONLY mine), as the screen is saying "Welcome" and the dot circle is spinning, I get a short screen flicker. It only happens once, and ONLY when I'm logging in.
I just updated my Windows 8.1 when I restarted my PC. When I was going to login, it was just a black screen. If you are in the login screen, the selected language in the right left corner and the internet connection in the left corner. Both of those two signs are flickering in the corners. And my cursor is also flickering.
View 3 Replies View RelatedToday I uninstalled MS Office 2010. After doing this it informed me I had to restart Windows 8 for all changes to take affect which I did. Ever since I have not been able to get into Windows 8.
Essentially I turn on the PC, I see the HP logo, and then Windows 8 goes in an endless black flickering screen loop. I have closed the laptop and pulled the battery to see if that was the issue, but it was not. Considering it was running normally before hardware wise I believe something went wrong with Win 8.
I lack a Win 8 disc and lack a USB DVD drive regardless (laptop does not have an internal drive) and reinstalling Windows is out of the question as I have data I need on it.
I am using a Ideapad Z580 with Windows 8.1 64 bit. All was working fine. But I formatted the C drive and reinstalled my Windows 8.1 OS. Then I installed all my drivers. After a reboot the screen started to jump(flickering).The top part of the screen(small portion) is appearing and disappearing in the bottom area. I tried to change the refresh rate.But it is locked in 60,and no other options are available.

I managed to launch task manager through ctrl-alt-delete (that didn't flicker, but taskmgr did). I launched cmd through taskmgr and managed to stop the flickering by terminating endless stream of svchost.exe processes. Couple of seconds after I do this, BSoD appears giving 0xc000021a error. Msconfig can't configure the PC to boot in safe mode. What do I do?
Windows is asking me for a password despite I've never had a password.
Here's what happened:
I've never had a password and choose during the win install to have 1 local account without password.
I used to have a user/login name with an non ascii character (é), and it was causing me some trouble. Hence I decided to change it with ascii only characters. Control Panel, users etc ... properties, changed the name of the local user.
Reboot, and boom, Windows asks me for a password and is displaying the former user name !! But there's no option to change the user name, I've read that there should be a back arrow but it's not here (probably because windows "thinks" there's no point since there is only 1 user).
I don't know what to do, I used a Linux live usb distro to use some tools that can reset password and unlock account, however:
1/ it can only reset password, which seems not to be the issue here, the issue is the wrong user name
2/ the linux tool shows 1 local user with the last update name
So I'm guessing windows is not using the proper name to login, but doesn't provide any mean to change it.
I have recently installed windows updates and after restart the black screen occurred after I typed my password. About five days before that I have reinstalled my Mobile Intel 4 series driver and now in Device manager it shows 3 grayed out monitors which were installed when I have reinstalled the Video driver. The monitor driver that Is currently loaded was installed when I installed the OS itself.

The first 'lockscreen' would appear, but the when I clicked to go to the next screen to log in, all I see is text in the bottom right hand corner telling me about windows updates that will automatically update in two days (I have already installed most of the newest WUs).... Having issues with the latest WU?
View 2 Replies View RelatedSince Yesterday I've gotten the Window's 8 Blue screen saying the Error "MULTIPLE_IRP_COMPLETE REQUESTS" now i got this multiple times yesterday, even got the "BAD_POOL_HEADER" Searched around and found out this was probably a Driver Error and updated my Drivers. Only my Video Card needed an update and after Installing the latest driver and restarting my Computer everything seemed fixed. But today i got the same IRP Error again.
I have an Busted up USB port and thought that maybe the Driver was confused about it and made the error so i Deactivated the specific driver to that Port, But after getting the same IRP error and restarted the comp again i got the "IRQL_NOT_LESS_OR_EQUAL" error at startup
Now my I comp started normally and I'm waiting for the next Error so I don't know what do to. I found out that there's some error Logs (C:/windows/minidump) but I don't know a program that'll make them readable.
I've recently purchased an MSI Dragon Edition. It started off the bat with top notch performance, no fps drops, no nothing, just pure perfection. Up until one day, it decided to completely crash on me, it got stuck on the loading BIOS screen and refused to redirect me to the log in page where i could access my desktop. After taking it to maintenance and formatting it from scratch, I've started noticing some subtle differences in comparison to the way it used to perform, performance drop, fps drop in game, slower powering on time, takes longer to shut down, not recognizing certain USB input such as my hard drive (not all the time).
About a week ago, while playing a game, my laptop crashed to the blue screen, with the error code displayed at the bottom telling me that the issue was "driver power state failure", after doing some research about the blue screen issue, people on other forums were discussing how the user should perform an SFD scan check from the CMD prompt.
After Scanning, my prompt informed me that I had multiple issues regarding my software files, "Windows Resource Protection found corrupt files but was unable to fix some of them."
From the Scan, there were in total 27 errors to report as shown below. I'm also currently fully, thoroughly scanning my laptop for any viruses using Avast! Antivirus, hoping it might resolve my issue.

Asus Vivobook. It was running fine last night, but today it was a bit slow to respond. I eventually restarted it and it told me I have disk problems. Now I'm stuck on a black screen with the Asus logo that reads "Repairing disk errors. This might take over an hour to complete."
It's been this way for multiple hours now. I'm going to leave it overnight and hope it repairs, but, if it doesn't, is there anyway to recover my files? I have some important stuff backed up online, but I haven't backed up in a bit over a month and I don't want to lose my files. Most forums tell me to reinstall Windows 8? Would that make me lose my files, though, and how can I do that if I can't get past this error page?
I'm administrator for my laptop runs windows8 pro.. I don't want every time have to type my password I tried using netplwiz but failed to do so, as looks as good only for second user ...

Today I changed my language options and happened to come across a BSOD. When I restarted, I found out that the input language for my password has also been changed, and my usual key combination for changing languages does not work. Thus, I cannot enter my password to change my language back to English. find a way to change the input language on the login screen?.
View 5 Replies View RelatedWindows 8 was fine. For Windows 8.1 I had Windows 8 format and do a clean install and then immediately upgraded to 8.1. Now at least half of the time when I boot up after BIOS info and the windows logo shows briefly I see a black screen for 2 to 5 seconds I'd say. Then the lock screen. So after I get to where I can input my password everything is fine.
But I can't figure out why there is this few seconds of black nothing before I can input my password. I can't see that anything is wrong.
I can log in, which takes much longer than ususal, to be taken to the desktop screen. everything is black except for the cursor and the windows icon in the bottom left. Ctrl+Alt+Del gets me to that normal menu and I can open task manager and from there open windows explorer and from there open most programs. I cannot get to the normal home screen, run disks or change tabs.
I have run start-up repair and enabled safe mode to no avail.
I cannot refresh or restart as i bought windows 8 online and have no physical copy of it.
After installing a game of Minecraft he claims that around that time, the computer has not been able to boot. So he brought it over to me, and I'm not to familiar with Windows 8. So I try turning on the laptop and it freezes at the login screen. It has his username, and the little loading screen like its trying to load the account, then it freezes and it stops there. So what I'm trying to do is a system restore to an earlier time. Maybe even to boot into safe mode. How to access System Restore is to hold shift while restarting the computer. Except I can't access the computer. It doesn't go past the login screen. I can go into the BIOS, but nothing else. Any method were I can do something to access system recovery another way? What I can do besides a system restore? But simply put.. Turn on, goes past the Asus loading screen, gets to login screen, username is displayed. Computer freezes. Sometimes it just goes to a black screen and stops there.

View 9 Replies View RelatedRecently I upgraded my Toshiba Portege R500 laptop from Windows 7 to windows 8 pro. Everything worked fine for almost a month and since last few days I am not able to see login screen, its just blank. Since I am unable to login I cannot access the apps/programs neither I can shut the laptop from Windows 8 via Charm menu or Cntrl+Alt+Del.
I am stuck as I cannot reinstall the OS as when I use power down button on the laptop the machine goes to sleep and on power up I cannot access boot priority screen to change to optical drive.
Right out of the blue, windows 8 loaded up painfully slow so i restarted my HP g6 laptop.After restarting the laptop the user login screen appeared fine fine but as soon as i login the metro tile screen flashes to a default coloured desktop screen and back to to the metro screen every second. It is continous and you can't access anything as the screen jumps to the other one before you can even do anything!
My laptop is only a few months old and there has been no hardware change/upgrade.I managed to get into the system restore and restored to a point a few days before this issue started but, when the laptop restarted, the issue remain and the screen jumped between the 2 screens.
There are no error msgs or any can of beeps that appear. There was nothing of any note that happened prior to this issue occurring and the laptop worked fine until this issue.
My issue is I have two users on my pc, after I reset(reboot) the pc on one user or shutdown, windows 8.1 automatically boots to that last user that was logged in and it's very bad behavior that I hate. I want to tweak it in a way so after i reboot or shutdown my pc on one user, and after I turn it back on or it reboots I want for Windows 8.1 to display me a login screen where I can click on a user with which I want to login. How can I make it to work like this? (also I want it so after that reboot and that login screen will be displayed the last user that was logged on will not be logged on still so I won't end up with two users logged on at the same time...)
View 2 Replies View RelatedOne day, I rebooted, and then there was nothing. After Windows finished loading, there was naught but a black screen, and a cursor if I move the mouse quickly. This happens in safe mode as well, and on both my dedicated graphics card (an Asus AMD HD 6450 Silent) and my integrated graphics (Other than it is a Biostar A780L3G). When I try to refresh directly, with a fresh copy of Windows 8.1 installation media, it says it is invalid, despite it being x64, same as the installed version. When I try directly, it says the HDD is locked, and none of the guides I have followed to unlock it through the disk work. Also, I dont know if this matters or not, but when I try booting into safe mode, at first, when I move the mouse, in the corners, it says Safe Mode.

View 2 Replies View RelatedRecently I downloaded the new Windows 8, replacing Windows 7. It was running flawlessly for a few days until recently when I restarted the computer, it won't even show the login screen. Everything is black, and I cannot even see my mouse pointer. I've been reading several people's similar problems saying to go into safe mode, but It won't even boot me into safe mode when I try. The screen just goes black.
View 1 Replies View RelatedI want to eliminate the password on the lock screen so my wife can get on the computer while I am out of the house. When I type "gpedit" in Run, I get the message, "Cannot find gpedit.msc. Make sure you typed the word correctly and try again."
Is there a way to access Local Policy Group by using the Windows Explorer?
I want to remove the mandatory login at the lockscreen. I don't need passwords on this computer.
I just got Windows 8 and tried disabling the log-in screen. I went into "netplwiz" now I seem to have lost my administrative powers.
I can't download programs or access the "user accounts" tab in the control panel. Every time I try to do something that would require admin powers, I get a "user account control" prompt that tells me that if I, "want to allow the following programs to make changes to this computer," that I need to enter an administrator password and then click yes.
But there is no text box to enter a password and the "yes" button is grayed out. My only option is to hit "no" or "show details."
When I go into "PC Settings" and the "users" tab, it says that "there are no other users on this PC" and "Sign in as an administrator to add users to this PC." But how do I do that?
I've tried going into the "run" operation and entered "net user administrator /active:yes" command, but nothing happens. I also tried entering "msconfig" but I ran into the same problem of not having admin powers to do that. I tried starting in safe mode by jamming shift and F8 but that didn't work either.
I just updated my Compaq Presario CQ56 Laptop.
It boots to the login screen. I enter my password and the screen goes black with just the mouse cursor on the screen. That is it nothing else happens. CTRL-ALT-DEL does not work. When the mouse goes away and I move it the cursor comes back.
I keep loosing the date/time main screen area after the computer is idle for any extended period of time.
When I move the mouse to log back in I get the main screen, but no time/date on the left side and I cannot log back in, no keys work.
I have to turn the power off and then re power up - then the time/date etc re appear and I can log in.
I already re freshed as instructed by Acer Tech support- but that didn't work.
I have a acer aspire laptop- 771-6865.
I have only one administrative account associated with my Windows 8 PC. I have this said account password protected yet my child can bypass the logon screen by merely resetting the PC. What kind of security is this?
How can I go about setting it up so that a password is require regardless of whether the PC is reset or not?
How are we suppose to go about keeping our children from unmonitored PC access if they can simply reset/shut down the computer and bypass it?
