    Screen starts to flicker after logging in for a while

    Hello

    This is an entirely new issue. My screen starts to flicker after logging in/turning on computer for a while, and/or if I launch an app that uses my Nvidia card (my laptop has Optimus), I'm not exactly sure which of these two causes it. For the first while after a restart, the screen appears fine. The flickering appears on desktop background + internet browser as well, so I'm pretty sure it's not a program compatibility issue. The flickering is not severe (the type that looks like horizontal bars sliding up) but it's an annoyance.

    Tried:

    • Disabling Windows error reporting + problem reporting service in msconfig
    • Restart computer
    • Resetting Nvidia global settings to default in Nvidia control panel
    • Checking for display drive updates in device manager (all up to date)
    • Checking monitor refresh rate (60Hz, can't be changed)

    Laptop I'm using:

    • i7-4700MQ 2.4GHz
    • 1900x1080
    • Intel HD 4600 + Nvidia GT750M

    Thanks for suggestions.

    Flickering and blinking laptop screen

    I'm using a laptop with Windows 10 and an Intel HD Graphics 4600 display adaptor. A few days ago I attached a Dell D3000 dock to my laptop, and almost immediately my laptop screen started to flicker and repeatedly blink off and on again. I disconnected the dock, which did not resolve the problem, and since then I've tried various techniques to fix the problem, but none of them have worked. In order, this comprised of:

    1. attempting system restore - but all five restore points were corrupted (?!);
    2. updating the driver for the Intel display adaptor;
    3. rolling back the driver for the Intel display adaptor;
    4. uninstalling the driver for the Intel display adaptor;
    5. downloading Windows 10 from the Microsoft site and re-installing it.
    The problem has persisted even when I disconnected everything from my laptop, took it to my workplace, and switched it on there (using its battery for power); so the following possible reasons can be ruled out: its location in my house, any attached peripherals, a faulty power cable.

    I am certain the problem is in some way connected to the Intel HD Graphics 4600 display adaptor:
    1. after I completely uninstalled it - which reverted the graphics card to the standard Microsoft one - the screen didn't flicker or blink once afterwards (I left the laptop switched on for about an hour without incident, whereas previously I would experience as many as ten 'events' a minute). This rules out a possible damaged connection between the body of the laptop and its screen. However, when Windows auto-installs updates it reinstates the Intel one...
    2. ...and when the laptop is switched on the screen flickers and repeatedly blinks off and on again...
    3. ...although, strangely, connecting an external monitor to the laptop (HDMI to HDMI) results in neither the laptop screen nor the external monitor flickering or blinking. The problem returns when I disconnect the HDMI cable from the HDMI port on the laptop.
    I now have the inescapable feeling that when I attached the dock I somehow fried the Intel display adaptor, and it isn't possible to fix it: I have read in the forums that replacing the graphics card on a laptop is well-nigh impossible. But if anyone else can suggest an approach I haven't yet tried I'd be very receptive!

    As an aside, I contacted the retailer and they have sent me all of the drivers that are available for my system, but I don't know how to install them.

    When Wifi is On my laptop started to Flickering

    High Ping when i Turn on the wifi of my laptop

    Can you please provide more information?

    • What make/model of router do you have?
    • Is it on the latest firmware?
    • If you don't know how to do something with your router, please refer to the user's manual or provide us more information about it so we can assist you better.
    • What make/model of laptops do you have?
    • Is the laptop that causes the high latency of the wireless connection much older than the other devices?
    • Have you scanned the device for malware to make sure it isn't causing any kind of attack inside or outside of your network? (I recommend MalwareBytes AntiMalware Free from Ninite.com)
    • What are you pinging when you're monitoring this issue? Google? Your gateway/router?
    High latency in a wireless envirnoment like this one I would assume it is either something overloading from a malicious attack, an old device using a narrower bandwidth causing the router to have to change its channel scopes and having issues doing so (firmware bug), or the router being overloaded trying to manage all the requests over wireless (cheaper home-grade routers can fall flat on their face if too many devices connect to their wireless network(s))...there are other things like channel interference that @remixedcat refers to that are absolutely worth looking into.

    Acrylic WiFi is an excellent program. Run it for about 15 minutes, then use Snip to take a screenshot of it (Google: Now to use Microsoft Snip, if you've never used it). You can attach images to a new post or upload them to Techpowerup.org and past the IMG code in your post.

    Hope this helps get you going in the right direction!
