Solved Taskbar Thumbnail Flicker
Jul 3, 2010
Running Windows Ultimate 7 x64.I have had the problem a few of you have had with the thumbnail previews on the Superbar flickering when you mouse over the icon.Its deeper than just the superbar screwing up. When this happens I cant highlight and play more than one song at a time with WMP Have to minimize windows just to return to browser and switch back and forth to windows explorer.I have to reboot my PC just to play a DVD folder or DVD disc.The problem started well into 6 months or more of using Windows 7 so I knew it was a problem with either some software I installed or a Component problem. I use Acronis for back-ups and have saved full back-ups of Windows 7 that I know are non-problematic , so after restoring a good image on a freshly formatted partition the problem remained.Tried all the obvious things like video drivers and all but still felt it was in the motherboard chipsets. Something had gotten corrupted or changed.
I have a Gigabyte MB and downloaded the drivers for Windows 7, installed.still there. Tried north bridge and south bridge.What I ended up doing was installing Windows XP x64 on a extra partition which allowed me to use my original installation disc for my motherboard and was able to individually install the drivers for both chips...and after the installation of the south bridge, the computer needed to reboot, at which time it went into a deep process (screen display with please wait or whatever) that took several minutes to complete.I dont remember it ever taking that long to complete .....talking ...like....6-8 minutes. I knew something good was happening.I know these drivers are for XP while in XP but I really wanted to do this just to see if it might get in there and root around deep in those chips since they are the original drivers.I never used XP x64 before with this AMD x2 5600+ I am currently using so I spent a couple hours installing a few programs I use a lot and testing them.Finally I rebooted back into my 7x64 (use EasyBCD) and have not had one problem with it yet. It has been 2 days since I did all this.

When I hover over a window in the taskbar, I only see words instead of a picture of the window; and I would like to change that. I have changed to an Aero Theme etc, but nothing is happening. I don't think I'm an admin on my computer. Please explain answers in layman's terms, I know nothing about computers.

Is there any way to speed up the time it takes to close the preview window? By default, it takes about 1.5 seconds for the window to close after moving the mouse off of the icon or preview pane.Turning off taskbar animations in the "visual effects" does not shorten the time. It just takes away the animation, but, it still takes about 1.5 seconds for the preview to go away.

I've put together a new clone system with the intent of running 64-bit Win 7 Pro on it. Until it becomes available, I have 32-bit XP Pro installed on it. Nothing is overclocked, in fact, the memory is "underclocked" for stability. I'd rather have it stable than gain some trivial performance improvement.
Previously, when I first built it up, I installed 64-bit Ubuntu "Jaunty" on it with 8 GB of RAM installed in it (4 X 2GB). The Linux distro installed and was perfectly stable.
To get a "heads up" on Win 7 issues, I downloaded and installed the trial Enterprise edition. Since I couldn't find any MD5 for the ISO, I downloaded the file twice and did a binary compare on the two downloads to ensure they were the same. Also, I see that the Java applet that downloads the ISO file also has some kind of "verify process" built-in that runs at the end of the download (a checksum?). I burned a DVD in XP Pro using Nero 8 with data verification on (after burning, it reads the burned disk and compares the disk's contents with the ISO file).
Since 32-bit XP Pro can't even fully use 4 GB, I uninstalled 4 of the 8 GB (two modules) when I installed XP on the box. When the entire 8 GB was in the MoBo, I ran MemTest86+ for long periods without errors. To do so, however, I had to "underclock" the memory to DDR2-800 speeds. It couldn't successfully run at DDR2-1066 speeds. A problem that, by checking various support BBS's, was found to be common with my MoBo and the RAM modules in question. After pulling the two modules, I left the memory timing at the conservative settings. I also let MemTest86+ run overnight and got no errors with the two modules installed. My plan is (or, was) to put the entire 8 GB of RAM back after I got 64-bit Windows 7 running on it.

Firefox browses and navigates fine, not a problem. Only when scrolling either with arrow or mouse, the background and sometimes the taskbar/system tray flicker. It's like you can see what window is open behind the browser view.I have tried using IE (not a fan...) and it didn't work so I uninstalled Firefox and attempted a reinstall only to find the problem remains.

I just got Windows 7 Home Premium today and installed 64bit edition. I must say, I'm over the moon. Great OS. Have a very small annoyance issue I was hoping someone could tell me is a result of a feature that I can turn off that isn't a major.
So here's what's happening
In Windows Explorer / My Computer when it's maximized "full screen", when I double click a folder and navigate around the directories, the screen changes brightness to bright then back very quickly to the original level (it basically flashes). If a folder only has a few other files inside of it, it even changes brightness when I hover over the icons.
It's not a major and doesn't do it when it's not fully maximized. Even if I make it the size of the screen by dragging the corners when it's restored down it doesn't do it. Very weird, and kind of hurts my eyes, especially when it's getting late at night and I should be in bed already.
When I disable visual themes, the problem goes away, but then it looks like rank, and I want to have all the flashy things that are unique to this version of windows, so...

I'll keep it short and sweet here. Just did the Windows 7 - 64 Home Premium install and did all the Windows and HP updates (yes, video driver is up to date - Nvidia 9300GSm). My screen is flickering for a 1/10th of a second every 20-30 seconds or so. It is incredibly irritating lol. Any ideas?

After doing upgrade desktop icons would flicker and after some time the screen resolution would change. Then computer would stop responding and would only respond after forcing reboot. I contacted Microsoft and they had me do a clean boot which stopped the problems.
I restarted non-Microsoft processes one at a time and the problem seems to be caused by NVIDIA Display Driver Service. As long as this is not running computer seems to be fine. Only question is this something that is needed to run? When on Vista Home Premium before upgrade to Windows 7 there was no problem with this running.

Sometimes fingernail-sized parts of my screen flicker. Are these called artifacts?
They smooth out when I drag the mouse pointer over them.
My drivers are as new as can be.

I'm having an issue with a newer pc laptop. Win 7 dual-core etc. During use the screen begins to flicker black every couple seconds. I've seen this before and it turned out to be an over-heating issue. I believe that is not the case in this situation.

I've been having this problem for a while now, and I really want to get to the bottom of it. The flicker takes the form of narrow vertical shadows moving across the screen horizontally. It isn't particularly noticeable on lighter backgrounds, but on a darker screen, it's really distracting. I notice it most when play Minecraft (in dark areas) and at darker scenes during DVD playback. I thought it might be that the monitor isn't getting enough power - there's my PC, an external HDD, surround sound speaker system and two lamps running off the same power supply - but I plugged it into a different supply, and still had the same problem.

I had this problem when I was just neutrally browsing through the internet when my screen just immediately flickered black, not for very long only about 1 second at the most, and my theme changed. I didn't really know what happened, so just kept browsing. I was browsing for about 20 more minutes and the same thing happened again, but this time it changed back. Recently just installed a new video card in my system, and have all the updated drivers, however, I wen't to CPUID to check the temps. of my system and my video card was pulling some numbers I haven't seen it do at this kind of browsing. My graphics card was about 67C and during regular web browsing it is usually around 30-35C. Is this a problem with Windows? Or is it a problem with my Graphics Card?

It mostly happens in Lightwave 9.6 and Photoshop CS2. So the problem is that when I open a drop down menu in those programs the program either flickers a lot or it goes in the background and I have to alt+tab to get it back every time. It is really annoying because I can't do almost all important things in Lightwave and I can't save images in other formats in Photoshop beacuse of the drop down menu, and in other programs it flickers a lot and is just annoying.

Memory Management Failure "IRQL_NOT_LESS_OR_EQUAL" System Service Exception
I recently bought two 2gb ddr2RAM and I am now using it.

this extremely annoying problem started the other day after i ran an energy report, which btw was the first thing i had done on the computer that day. so the energy report may or may not have something to do with it.
the problem could be referred to as several things really, jittering,
flickering, flashing, even kind of a bounce maybe....its just real quick, a split second at a time. depending on what im doing, it can be as often as every 3 to 5 seconds, or just intermittently.
heres a list of when the problem occurs.
1. watching vidoes online. hulu.com so far is the worst. picture flickers every 3 to 5 seconds. Internet much better, just every so often. watched one full show on nbs.com. didn't flicker once....!!?
2. flickers in game loading screens but not in game. thank god!
3. also when i launch an app or maybe a video offline it'll flicker once as it launches.
here's when it dosent occur.
1. in games. (outside of the loading screen of course)
2. outside of watching video online there is no problem as far as browsing etc.
3. no flickering on the desktop, or when navigating though windows.
to fix the problem ive tried windows restore, and reinstalling my video card drivers. neither fixed my problem. outside of doing a reformat i dont know what else to do.

So I just recently upgraded to Windows 7. After installing all the necessary drivers provided by Windows Update, It was time to install the one provided for the Graphics Card. Ever since I've got the driver set, there seems to be this flicker on the screen that tends to show up every few seconds.

I have a Dell Inspiron 1012 running Windows 7 Starter SP1 and I've got it hooked up to my Protron 42" LCD screen with HDMI cable. I changed the flicker rate to 70 Hertz without checking the Proton's maximum flicker rate - yeah, that's really SMART - so now I've got an issue with my external display.It worked okay for second but then my laptop screen turned black and the external display reads "Signal Out of Range" (duh, the Protron works only up to a 69.8 Hertz flicker rate, which I SHOULD have checked BEFORE changing it, but what's done is done -_-).Now, when I plug in the HDMI cable, my laptop screen goes to black and the external display still reads that same message. I can't change the flicker rate without seeing the menu on my laptop screen.
