It sounds like you are experiencing a significant issue with your HP all-in-one desktop, particularly with the mouse behavior and screen display. Here are some steps you can take to troubleshoot the problem:
- Check for Hardware Issues: Ensure that there are no physical issues with the mouse or keyboard. Try using a different mouse or keyboard to see if the problem persists.
- Update Drivers: Outdated or corrupted drivers can cause erratic behavior. Make sure to check for and install any available updates for your display and input device drivers. You can do this through the Device Manager:
- Right-click on the Start button and select Device Manager.
- Expand the categories for Mice and other pointing devices and Display adapters.
- Right-click on your devices and select Update driver.
- Boot in Safe Mode: Booting your computer in Safe Mode can help determine if the issue is caused by software. To do this:
- Restart your computer and press F8 (or Shift + F8) before Windows starts loading to access the Advanced Boot Options.
- Select Safe Mode and see if the problem persists.
- Run System File Checker: This tool can help repair missing or corrupted system files. Open Command Prompt as an administrator and run the command
sfc /scannow. - Check for Windows Updates: Ensure your operating system is up to date, as updates can fix bugs and improve performance. Go to Settings > Update & Security > Windows Update and check for updates.
- Contact Support: If the issue continues, it may be best to contact HP support or a professional technician for further assistance, especially since you mentioned that resetting to factory settings did not resolve the issue.
These steps should help you identify and possibly resolve the issue with your HP all-in-one desktop.
