Windows 8.1 Laptop Display Flashing
Oct 26, 2013
I have a problem of windows 8.1 and my laptop (HP EliteBook 8560w). My display is full HD (1920x1080), 15.6", GPU: nVidia Quadro 2000M. When I installed windows 8.1 (all version, 64 bit) the GPU driver is updated automatically at lastest version (327.31). But some 3rd application ex: Google chrome... is blurry. Then, I chosed the option "Let me choose one scaling option for all my displays" at 125%. All thing is OK.
But whenever I started my windows, my display always flashing one time, about 1-2s. it's very inconvenience. Because of that problem, I downgrade to windows 8.0. But i still want to use windows 8.1 ....

I have a Windows 8 HP laptop and the screen is just flashing. I have looked through other users posts and tried a few things but nothing is fixing the issue. I can't get past the flashing screen to enter Control panel, Safe boot or anything as the flashing is preventing me getting anywhere!! Lots of photos not backed up so don't want to lose them!

i was customizing my desktop with Rainmeter and i wanted to know how to change my toolbar's color because i didnt want the blue, someone said to download Vistaglazz and repatch some files. after doing so my computer restarted and after the initial normal startup and it saying "Please wait..." like it usually does before it shows the login users, the screen went black, then for a split second the screen went pitch black, almost as if the computer turned off, then it would turn on again and go back to the normal "Please wait..." screen. this would be ok but its happening so fast and over and over again that i cant even hit f8 or Ctrl Alt Delete. im using a different computer because i literally cant log onto the other one.

Since installing Windows 8 to my laptop, I can no longer display to my Samsung USB hub monitor.
When I try to duplicate or extend, the hub says 'Connecting to PC...' but then nothing happens. Something is working as my mouse and keyboard are plugged into the hub and they work. I just cant get the display. I think all my drivers are up to date.

I've just bought a Toshiba L855 with Windows 8 factory installed. So, I'm trying to learn two things at same time, Windows 8 and the laptop functionality. One of the details that I don't like is the automatic power on and boot up every time I open the display, regardless... may be useful for other users, but not me.
Although there is an option to disable that Panel-open/Power-on, still does it! The "disabled" status is there, but nothing changed. It keeps starting up.
I haven't installed anything yet to the PC until I'm really sure there is nothing wrong with the hardware, I hope is not a warranty issue.
BTW, I have two administrator users, my wife and I. We tried disabling that power up with each user logged and still won't work.

I've upgraded to windows 8.1 a few days ago through a custom install as I was running windows 8 x86 and wanted to switch to x64. I've also just updated the BIOS.
After the upgrade though, my laptop goes into sleep/standby and locks the screen instead of turning off the display as I have it set. So, if I edit any power plan settings to turn off the display after 2 minutes, it will go to sleep after 2 minutes.

Downloaded this AM to 8.1 from Win 8. Have an old Gateway laptop, can't afford to get new even though I need one. The display is very dark - it was fine with Win 8. Is there some setting I need to change - can't find any way to make it brighter. Like I said, it was fine before & I didn't change any settings myself.

My dell inspiron n5010 running on Windows 8, today all of a sudden started showing some grains on the display.Soon after it happened, it showed me a message which says
"Your PC ran into a problem and needs to restarts. were just collecting some error info, and then well restart for you (100% complete)".
The system restarted by itself and it started running system repair. The system repair screen is also grainy. After the repairing is done, it restarted showing Windows 8 logo(that too with grainy display).But nothing really happens after that and it its stuck. So I decided to switch it off and turn it back ON after sometimes. I did that and the PC booted with no issues with the display perfectly fine. But the same issue is repeating again and again and I will have to shut down the system for some time and then again turn it back ON to make it run normal.

Since I have installed windows 8.1, every time for example if I don't use my laptop for 10 minutes, and because of the battery saving setting plan, my display turns off. Before I installed windows 8.1, I could just move a mouse or press any key and display would turn on, but since the installation I have to restart my laptop (Samsung ultrabook), even if I can hear it's on and working.

I have an Acer Aspire laptop which has recently stopped booting up. It doesn't display anything when powered on. I know it is not a problem with windows because it doesn't even display the Bios boot screen. Why is this? The fans start but I cant hear the hard drive.

I have a new Dell Inspiron 15 7000 laptop with an i7-4510U, Intel 4400 Graphics, 1920x1080 screen, and Windows 8.1. I have noticed that the display will brighten and dim when switching between apps. For example, going from a dark desktop background to a white background such as File Explorer, it will take the display about 5 to 10 seconds to brighten to the appropriate level. Going back to the desktop it will dim and sometimes even show a quick flash. I have the display set at 60% brightness and have turned off the adaptive brightens. Also using the latest Intel drivers. Exhibits this behavior on battery or AC. Never seen this on a laptop before.

I turned on my laptop and after I logged on all my letters were replaced with symbols. I then restarted my laptop and now even my log in screen is symbols and when I get to the desktop my screen just keeps flashing and I can't click on anything. It just keeps flashing and loading nothing. I can't do anything on it. I didn't install anything the last time it was on either and I'm the only person who uses the laptop.

My problem is since updating to 8.1, whenever I fire up IE11 on desktop mode a Windows Installer box shows in the middle of the screen saying "preparing to install" and the box continually flashes and the webpage will not load. Why this happens! IE works fine in metro mode and I cannot find any logs in Event Viewer with regards to this problem.
PC is a Dell XPS8500, seven months old.

I have hp pavilion g6-2249 wm notebook. My laptop is 4 months old. Two days ago when I started my pc, the welcome page opens and then I sign in. Everything is ok on the apps page that immediately opens.If I click the desktop app icon, it goes to the desktop and the entire page starts to flash, it shows the desktop for 2 seconds and then then flashes to blue for 5 seconds and back and forth, etc.
The desktop will not stay open long enough for me to do anything. I cannot get it to start in safe mode. I clicked F8 repeatedly on start up but nothing happens. I used the esc on startup and ran every test offered except BIOS. I don't know what to do with that so I didn't mess with it. All tests were ok.
If I go back to the app page from the flashing desktop, the app page and charms start flashing also. I can't even shut down properly then. Norton 360 runs in the background all the time but I can't get to it to do a scan. I can't get to any file. The only way to get online is to turn off pc and turn on later. App page does not flash at that time. I go to search and click on Explorer and I can go to my homepage. If I click on required addons then the background starts flashing and I have to reset my cursor every two letter that I type.

I just got a new laptop (Toshiba Satellite C850) that came with Windows 7 pre-installed so I decided to get windows 8 Pro at the discounted price. I downloaded it and so far I love it. However, one thing I noticed was that when I am using some downloaded apps (Shazam, Khan Academy, etc...) these crooked, horizontal black lines appear at the top of the screen every once and a while and almost make the screen shake.

I recently started having the black screen with the flashing cursor come up sometimes when I start my PC. I have narrowed it down as being my 3rd HDD (2TB WD) as the culprit, which I only use as media storage. It is not set as a boot device since windows is on my SSD and when I unplug the drive from my mobo, windows always starts up without any issue.
Basically my question is, is this just a case of a hard drive going bad? I ran chkdsk on all 3 drives and none of them had any issues and it is not fragmented or anything that I can tell, so I don't know. I have had this setup for a while now and about a month ago it started doing this. The screen doesn't always come up however, so I have no clue what the issue is.

I had to reinstall the whole machine from scratch because old HDD has been playing up. This is what I did:
1. Imaged old (faulty) drive to new one - just because I needed some data out of it and the old one was very slow and freezing.
2. run the system with new imaged drive - all working except sometimes it was playing up, so I decided to upgrade to another drive with Windows 8.1 from Win7
3. have plugged in new HDD to SATA0 port and the imaged drive to port SATA2
4. installed Windows 8.1, copied data over, reinstalled applications and so on.
5. all working perfectly. Now every time I boot up the machine, I'm offered options if I want to boot to Windows 8.1 or Win7. No problem there.
6. Now I wanted to remove the imaged HDD from SATA2 port, so I did - and here comes the problem:
All I get now is the black screen with flashing cursor in top left corner. How is this possible ? When I plug the second drive in all works as before. I just have to remove the second drive. How can I do this? In the attached image you can see my drives from Windows 8.1 the Disk0 is the one I need to keep - that's a Windows 8.1 ( C: ) Disk1 (imaged HDD) is the one with Win7 on it and needs to be removed.

I was messing around with my screen resolution settings when I switch over to portrait mode on desktop PC. When I hit apply the screen started flashing and it went to protrait. I saw thye option to revery back but with they screen flashing I couldn't hit it. Then the settings set in and the screen went back to the sigin in menu in portrait.
I can enter my password, sign in, and then it tries to load the start menu but the screen starts flashing and after about 8 seconds, it goes back to the sign in menu. Now I am stuck in this process and cant get back past the sign in screen to access the control panel and set the screen back to landscape.

The caps lock light on my HP Pavilion G6-2356sa is flashing. The button still puts the letters in capitals, so it still works, just continually flashing. It's just stopped flashing actually.
Anyway, I've had a Google and all the results I've found say it has a black screen at the same time.

I have a lenovo twist running windows 8.1. This computer will be running run fine but will freeze then come right back. It also will not wake up from a sleep at times and the only way to get it back on is to cut all power or hold down the power button until it shuts off. It just started not being able to do some of the windows updates.

I am on my laptop at the moment and am trying to make a BIOS update stick for flashing my main desktop at home that has an Asus P8Z77-V board.
Now I have downloaded and saved both the BIOS utility - renamer and the BIOS version itself and both are zipped files.
I have tried using 7-zip to rename that BIOS file which the manual tells me I have to do but to get it to work when I use the 7-zip it goes to choose an app from the store. Now I have never fully understood zipping and unzipping files to be able to use the application and now this message has got me even more perplexed as to what to do!
I did try this at home on the main machine but I did go round in circles on that (7) machine and until I get the BIOS ready on the stick I cannot flash the BIOS on that main machine.

I have recently installed a new Video Card a Gigabyte GeForce 660 GTX, when I'm playing video's or if I open the Geforce Experience program from the task bar the screen goes blank for about a second then returns to normal, it always seems to happen when I get the program to check for updates. I am using the latest driver 320.49.
When I play games there's no problem occur so I don't think it's the card it's self, I suspect it's something to do with the program.

My PC was working fine before today, until I used Ultra UXtheme patcher for Windows 8 x64 and then applied a custom VS for Windows 8.
After a restart, Windows Explorer was not launching, so I opened task manager and did a sfc /scannow. After a reboot, I get to the Windows 8 boot menu (I have a dual-boot on this HDD with win7), and then the screen just turns on and off every few seconds, with the numlock light flickering with the screen.
I tried using the automatic repair, both from the boot menu and from a backup USB, but it does not detect anything. and I still have the same issue.
I restored the backups of uxtheme.dll, uxinit.dll, and themeui.dll, but that didn't work either.
Attached is my ntbtlog.txt.
There is no BSOD, the HDD keeps on spinning a few minutes after boot, and the numlock keeps on flashing. Anything else I can do from my win7 install? I'm currently trying to delete the theme.
Deleting the theme doesn't work, safemode doesn't work either. It seems to be a driver issue, but there were no driver updates when it was working?

I am coming off Linux op system and am a bit lost. My latest endeavor is understanding the Windows 8 partitions.
I have a Dell Inspiron 5721, 8 GB memory, 1 TB hard disk, with Windows 8 O.S.
Looking at the partition display, I see the disk is divided into five partitions. The partitions are named:
"500 MB, Healthy ( EFI System Partition)",
"40 MB, Healthy (OEM Partition)",
"500 MB Healthy, (Recovery Partition)",
"OS (C:, 917.77 GB NTFS, Healthy (Boot, Page File, Crash Dump, Primary Partition)",
"12.60 GB, Healthy (Recovery Partition)".
All of these partition, except for the NTFS partition, are listed as 100% Free. The NTFS partition is listed as 88% Free.
Are these partition available for use, or are they being used for something(?).
I am working on the boot situation, trying to find out how to input from the cd/dvd writer, but have not over come the "Secure Boot" thing yet. That will be next on my agenda.
I am attaching a copy of the data partition scheme ....

So I upgraded to Windows 8 today and finally finished all the installations only to find that using a 1920x1080 resolution means that the display is too big for my screen (a 32" Samsung full HD TV). The screen is cropped by about a half a CM all the way around. I had to revert to a 1776x1000 resolution for the display to fit properly on the screen but would much rather use the highest possible setting but I cannot seem to fix the problem.
I am running 64-bit and have updated all display drivers and completed windows updates. My GPU is an ATI Radeon HD 5800 series.

Microsoft uses a display server? I assume it does but I am doing a presentation on display servers and I found a ton of information on Linux and OS X display servers but I cannot find anything on the display server Windows uses.

I have run into an issue with a Pavilion g60-230us laptop. After going to sleep or closing the lid, when I open the lid again the laptop wakes up, but the display never resumes. I can see it kind of try to come on, but nothing ever shows on the screen. I am currently on Windows 8.1 Pro. The system is 32 bit and not running a separate display adapter, just the integrated Intel configuration. I have tried downloading the latest Windows 7 driver from the HP support page for the g60 but it didn't work. They don't offer drivers for Windows 8 on this model. I have also deleted the display in device manager, rebooted and let Windows find and install its own driver, but this also didn't work. Keyboard and mouse both have the box checked for allow this device to wake the computer in the power settings.

I've noticed sometimes when I first powerup my windows 8 machine, it turns on, but I get no display on my monitor (has happened with 2 monitors). I am using the latest beta ATI drivers for my card. The weird thing is, pressing delete i dont even get the bios to appear, just a black/dark monitor screen. I am wondering if repairing the bootloader could fix this? How to repair the bootloader? I won't loose any of my data, will I?
After turning off, turning on the computer a few times, I finally get display and can get into windows 8, but it's annoying.
MB is an ASUS P8z68V/gen3
