Daryl is running Windows 8.1, but after a so-called critical update, he gets a black screen. Leo says that sometimes an update can break something, and it sounds like it may be an incompatible video driver. First thing to do is to boot into Safe Mode. Then, if his screen comes up, that indicates a driver issue. Daryl should go to the video card manufacturer's website and download the latest video driver.
John built a Windows 10 machine, upgrading from Windows 7. But now it's slowing down while playing videos and he has to do a hard reboot to restart it. Leo says there's a setting in the video driver that is for "hardware acceleration." If it's on, he should turn it off. If it's off, he should turn it on. That may fix it. He can right click on the desktop, then click through the following: personalize, display, change display settings, advanced settings, graphics property box, troubleshooting, change settings, display adapter troubleshooter for hardware acceleration.
Larry is having trouble with his NVidia video card which keeps crashing, especially when watching HD video. The screen will go black and he'll get awful sounding audio. Leo says that's a sign of a bad or corrupted driver that will write improperly to the memory buffers. The only thing that can do that is Windows itself or a driver. Reinstalling the driver could solve the problem.
Mike's home built computer crashes when he closes a program. The screen turns black and hangs up. It doesn't work again unless he reboots it. Leo says that's the hassle with building his own -- he has to eliminate each issue. Leo says the first thing to do is update his video card driver. He thinks it may be a bad driver. Leo says he can try booting to a USB key with Ubuntu on it and try to repeat the issue. If it repeats, he'll know it's a hardware issue. If it doesn't, he'll know it's a software issue.
Alan has an old Dell computer and he is having trouble using Windows 10 because of the video problems. Leo says that Windows should be able to automatically read the native resolution and adjust accordingly. For some reason, Windows thinks the aspect ratio is wrong and it's stretching it to widescreen. It could be a driver issue. It may also be the text file that describes the attributes of the monitor. It's called a monitor driver.
Gerald wants to know how he can upgrade his video drivers without paying for them. Leo says he shouldn't have to pay for drivers, they will come with the hardware he buys. So he should avoid any scam that requires him to pay for a driver. Chances are, Windows Update will have the driver update anyway. He can also get the Windows HQL driver. It's Microsoft certified and is usually the most bug free. Then there's NVidia's certified drivers at NVidia.com/downloads.
Ian installed Splashtop remote desktop to his PC so he could control it from his iPad. But now the icons are all spread out in a weird way. Leo says that's a resolution issue between his iPad and the desktop. It doesn't remember his layout, and it'll change it back and forth rather than present it as he set it up. Leo suggests going into the Windows Display settings and changing the resolution to a proper setting for both. But in Windows 10, there's actually two display menus, one for touch screen, the other for the laptop.
David is getting a blue screen when trying to use Skype and Windows 10. Leo says uninstall it. Then he should reinstall the desktop version of it, not the Metro version. The issue could be with a driver for his video camera. If the camera is built-in, then he'll have to go to his laptop manufacturer (in this case Lenovo) and get the latest drivers. While he's at it, he should get all of them.
David is getting an incompatibility error when updating to Windows 10. Does he need a new video card? Leo says no, that isn't necessary. The updated drivers should be out in a relatively short period of time. So David should just wait for a new video driver to become available before he updates. He has up to a year to upgrade for free.
From the chatroom, there are some older video cards from NVidia that Microsoft said will not support DirectX 12 for Windows 10. If that's the case, then he will have to get a new video card. But they're pretty cheap these days.
Ed downloaded the game "Middle Earth: Shadow of Modor," and then got a message that said "installed video does not support DirectX features." Leo says that this is one of the reasons why he prefers console games because they don't do things like this. But in Windows, the PC has to meet the games' specifications.
