Common Computer Boot-Up Problems and How to Fix Them


When using a computer, first thing you need to do, of course, is to start it up. But what happens when your computer fails to start up properly? How do you fix it? Here are some common startup or boot up problems and their solutions.

1. Blue Screen of Death or BSoD

This boot up problem commonly occurs when you installed a new hardware or software, wherein the change you made caused the BSoD error. Your computer will then stop responding, will suddenly flash a blue screen, and will automatically reboot in order to prevent any permanent damage to your hardware. Another reason for BSoD is getting a malware infection on the computer.

Fixing BSoD starts with the error code, this code is in the BSOD itself (Fig. 1); most common errors are pertaining to bad drivers installed to the computer. Resolution to this scenario usually requires booting the computer in Safe Mode (Fig. 2), and then removing the faulty driver.

For BSoD caused by a malware infection, users can boot into Safe Mode and run a malware scanner and remove the malware that is causing it.

2. NTLDR is missing

This boot up problem is usually encountered after virus removal or computer cleanup, and is usually common in Windows XP. Users have reported that this boot up issue usually surfaces after the removal of “Conduit SearchProtect.”

There are ways to fix this issue depending on the operating system the computer is running on. For Windows XP computers, this would involve having the Windows XP CD and a working CD/DVD drive. This involves copying an original copy of the missing NTLDR from the CD to the current Windows directory, which will require the user to boot from the Windows XP CD and entering the Recovery Console to execute the copy command and resolve the issue (Fig. 3).

3. HAL.dll is missing

The HAL.dll file is a hidden file that is used by Windows XP to communicate with your computer’s hardware. HAL.dll can be damaged, corrupted, or erased for a number of causes and is usually brought to your attention by the “missing or corrupt hal.dll” error message.

In restoring HAL.dll, the user must have the Windows XP CD and a working CD/DVD drive. The user will need to boot from the Windows XP CD and enter the recovery console. The user will then copy the original HAL.dll from the CD and overwrite the corrupt HAL.dll on the System drive (Fig. 4).

4. Slow Start-Up

Slow start-up is a result of numerous start-up items that are left to start in the boot up process As a result, the computer will take a longer time to start up thus it will take longer for the computer to be available for the user.

For slow startup, modifying the startup items will eliminate that. In doing this, it will take less time for the computer to start-up. Doing this, the user must access the System Configuration Utility (Fig 5) and uncheck unused start-up items from there.
