For most devices, this means holding down the power button until the PC shuts down.Ī minority of devices may have the power button action redefined so that the PC keeps running despite this action. In such cases, there’s really only one thing to do next: forcibly power off the affected PC. If the cursor is absent, these key combos often won’t help - and sometimes they don’t help even when the cursor is present. If this screen does appear, click “Cancel” (as shown) and your desktop should reappear in working order. What this screen capture doesn’t show is the power buttons at the lower right, with networking, ease of access and power controls (shut down, restart, and so forth) from left to right. And sometimes when that’s the case, this key sequence will repaint the screen to show you the secure log-in options. Ed Tittel/IDGĬtrl + Alt + Delete invokes the Windows 10 secure sign-in screen.Įven when the preceding combo gets the graphics driver going, it sometimes still won’t light up the screen. Starting with Windows 95 (and Windows NT version 3.5), this key combination now invokes the secure sign-in screen shown in the figure below. It’s notorious to those who’ve been using Microsoft OSes for a long time (since the mid-‘90s or earlier), because it used to forcibly reboot the OS when struck. This is a familiar key combo to longtime Windows (and even DOS) users. Then it’s time to try the second sequence. Sometimes, nothing else will happen after the disk activity light ceases flashing. Sometimes the screen will return to normal operation a few seconds later, showing that the driver has reloaded and is now running successfully. If you see immediate disk activity (from a disk activity indicator), that’s a good sign. I usually do the first three keys with my left hand, then press the B key with my right forefinger while the others remain depressed. This keyboard combo reads: Windows key + Ctrl + Shift + B. ![]() Most Windows 10 systems use only a single graphics driver, but those with multiple graphics cards (or card plus chipset) and multiple displays may have multiple drivers running. This four-key combination tells Windows 10 to stop, then restart any and all graphics drivers that happen to be running. This usually means using one finger to depress the first key and holding it down, using a second finger to depress the second key and doing likewise, then more of the same for a third key - and one of these two combinations requires adding a fourth and final key as well. Two keyboard combos can (usually) restore normal operationsīoth combinations involve pressing multiple keys simultaneously. This means that there’s a very good chance that the desktop can be restored to normal operation using a few well-known key combinations. It indicates that the OS is still working (at least to some extent) behind the scenes, and that the mouse driver can still track cursor position onscreen. The presence of a cursor that responds to mouse movement - as it often will - is actually a good sign. Second is a problem with the graphics driver, the special software that interacts with the display on behalf of the graphics subsystem inside the OS to render pixels on the screen, itself. First is a failure of the graphics subsystem to interact with the display upon waking from sleep. I’ve found that two causes are the most likely culprits when a black screen with cursor appears. In my personal experience, the black screen with cursor occurs far more frequently than a black screen by itself (no cursor). The image at the top of the story shows what this looks like. Often, the cursor will track mouse movement even though it’s mousing over a completely black screen. The second is what’s called a “black screen with cursor.” Just as it sounds, this means that the display is completely black, except that the mouse cursor is shown on that black background. This means the screen is completely dark with nothing at all showing. ![]() The first is a black screen, plain and simple. Windows 10 cognoscenti recognize two different types of black screen in the Windows 10 world. Two kinds of black screen, with one subtle difference ![]()
