Is your Dell PC having trouble powering on or booting into the operating system? This article helps you find troubleshooting guides for no power, no post, no boot, and no video issues based on your Dell PC's symptoms.
If your Dell PC does not power on or boot into the operating system, it is recommended that you perform a hard reset first. Performing a hard reset usually fixes many problems and also drains any residual power that may be causing the problem. If your Dell PC still does not power on or boot into the operating system, follow the appropriate actions below based on your Dell PC's symptoms.
