Fix computer, laptop and internet problems with step-by-step guides for Windows, Wi-Fi, routers, browsers, peripherals, performance and reliable everyday connectivity.
To scan photographic negatives, clean and flatten the film, place it in a scanner’s transparency holder, and use the film or negative mode at the holder’s optical resolution. If you do not have a film scanner, photograph the negative evenly backlit with a camera, then invert and correct the image in editing software. Check every frame at full size before saving.
To change your Wi-Fi channel, sign in to your router’s app or web control panel, open Wireless, Wi-Fi, or Advanced Wi-Fi settings, select the 2.4 GHz or 5 GHz band, choose a less congested channel, and save. Reconnect your devices, then check whether the affected room or device has a steadier connection. Router menus vary by model.
To stop Microsoft Edge from opening on startup, turn off Windows’ option to automatically restart apps: open Settings > Accounts > Sign-in options and disable “Automatically save my restartable apps and restart them when I sign back in.” Then check Settings > Apps > Startup and switch Microsoft Edge off if it appears. Restart Windows to verify.
To clear the cache in Microsoft Edge, open Edge and press Ctrl+Shift+Delete. Set Time range to All time, select Cached images and files, clear any unwanted options such as passwords or cookies, then select Clear now. Close and reopen the affected page. If the problem remains, test the site in an InPrivate window before deleting more data.
Google Read&Write usually means Read&Write for Google Chrome, a Texthelp learning toolbar for reading, writing, and research. Install or open it through your approved Chrome account, sign in if your school or organization requires it, then select text and use the toolbar. Available tools can vary by license, account, and administrator settings.
DRIVER_POWER_STATE_FAILURE usually means a Windows driver did not handle a sleep, shutdown, restart, or power-state change correctly. Disconnect unnecessary USB devices, restart, and update or roll back the most recently changed graphics, network, storage, or chipset driver. If Windows will not start normally, use Safe Mode to remove the recent change before trying broader repairs.
A Dell computer entering power saving mode usually means the monitor has lost its video signal, not that the monitor itself has failed. Wake the PC, confirm the monitor's selected input and cable connection, then restart the computer. If no Dell logo ever appears, treat it as a startup or hardware problem rather than a Windows power-setting problem.
Open your browser’s bookmarks or favorites list, select the saved link, and choose Delete or Remove. On a computer, you can usually right-click the bookmark; on a phone, open the browser menu, choose Bookmarks or Favorites, tap the item’s menu, and select Delete. Check the list again to confirm it disappeared.
On a Windows PC, press Windows + Shift + S to select part of the screen, then click the preview to save or edit it. For the whole screen, press Windows + PrtScn; Windows saves the image in Pictures > Screenshots. Pressing PrtScn alone copies the screen so you can paste it into Paint, Word, or an email.
The YouTube audio renderer error usually means Windows and YouTube cannot share or reach the selected audio device. First restart the computer, then select the correct output in Settings > System > Sound, reconnect headphones or speakers, and restart the Windows Audio service. If the error remains, test another browser and update the audio driver.
