Desktop Never Appears

Windows just won't finish loading. I stare at the Windows logo for what seems like an eternity, and then the pulsating progress bar stops pulsating. That's it; Windows never loads. What's going on?

When Windows boots, it loads all of its drivers, initializes its network connections, and loads its high-level components (Explorer, fonts, etc.) into memory. These things are loaded in order; if one task cannot complete because of a corrupted file or network error, for instance the next task cannot begin and the boot process stalls.

Note: If you're running off a battery, plug your laptop into its charger and wait for about 20 minutes for the battery to accumulate sufficient charge to start Windows.

If the problem started happening as soon as you added a new hardware device, check the device manufacturer's web site for a driver or BIOS update. Otherwise, first unplug your network cable and try again. If Windows loads, there's something wrong with your network connection, Internet connection, router, or whatever else is on the other end of that cable.

Still stuck? Unplug all the USB and FireWire devices connected to your PC. If Windows loads, reconnect them one by one, restarting Windows after each reconnection, until you find the culprit that hangs the system. Really stuck? Start disconnecting any non-USB peripherals (e.g., keyboard, mouse, parallel printer) attached to your PC and, if necessary/applicable, PCI or PCMCIA cards and any other nonessential devices inside your PC. If the above steps don't work, there may be a problem with your hard disk but if you're getting as far as the Windows logo, it's probably not too serious. To investigate, restart your computer, and just after the beep but before the Windows logo appears, press the F8 key. From the Windows Advanced Options Menu, use the arrow keys to highlight Safe Mode, and press Enter.

Safe Mode allows Windows to load without network support, hardware drivers, some services, and a handful of other components that can sometimes cause this problem. If Safe Mode works, open Windows Explorer, right-click your hard disk (e.g., drive c, select Properties, and choose the Tools tab. In the "Error-checking" section, click the Check Now button. Check the boxes next to both options in the "Check disk" section and click the Start button, and ScanDisk will open and check your drive for errors. When it's finished, restart Windows normally.
