Troubleshooting Common problems

Below is a list of common problems experienced while assembling a PC. Please check the list which could have the possible solution to your problems.

1. Problem: The PC does not boot, the power and HDD LED does not come on, there is no display on monitor.
Solution: Check that your main power cable is plugged into the ATX power supply. Make sure you have connected the ATX power connector to the motherboard. Check if the cable for the power switch at front of the PC is connected to the correct pins on the motherboard.

2. Problem: The power LED comes on but the PC does not boot, there is no display on monitor.
Solution: Check if the processor is firmly into the socket. Check CPU jumpers to verify if CPU frequency is correctly set.

3. Problem: The PC does not boot, but is beeping.
Solution: Different BIOS manufacturers use various number of beeps to indicate faults with various hardware. In an Award BIOS motherboard you will get following beeps:

1 long 2 short: Graphics card is not securely into place, or faulty.

1 long 3 short: Graphics card is not securely into place, or faulty video memory.

Continuous beeps: No memory, or memory not securely into place, or could be faulty.

Continuous high/low beeps: No CPU, or CPU not securely into place, or could be faulty.
Please refer to your motherboard manual to confirm what the beeps are trying to tell you.

4.Problem: The PC boots but the CPU speed is incorrect.
Solution: The CPU frequency jumper setting is incorrect. Refer to your motherboard manual to set it correctly.

5.Problem: The HDD is not being detected by the BIOS.
Solution: Check if you connected the IDE cable to the motherboard correctly, is pin 1 on the IDE cable connected to pin 1 on the IDE sockets on both motherboard connector and HDD connector. Check if the HDD jumper is set to master and any other device sharing the same cable is set to slave.

6.Problem: I can not access my CD/DVD-ROM in DOS mode, hence can not install Windows.
Solution: CD/DVD-ROM device driver is not installed. Install the manufacturer supplied device driver. If you do not have a device driver disk, you can use the windows boot disk which will provide access to your CD/DVD-ROM, so that you can install Windows.

Blue Screen of Death (BSOD)

One of the most dreaded error messages for a Windows user is the blue screen, or the Blue Screen of Death (BSOD) as it is popularly known, which suddenly pops up informing you that something is seriously wrong with Windows. What this screen essentially means is that Windows has crashed and needs to reboot to recover. Usually, you will be able to recover and continue without any problems.


Problems causing BSOD :
The BSODs are generally associated with five problems faced by Windows:
  • Software or device drivers may have a problem.
  • A hardware device is malfunctioning , or was removed while Windows was running, or does not fully support Windows. On older machines, outdated BIOS information can also cause errors.
  • Hardware or hard disk errors during installation of Windows.
  • Startup files , hardware and driver software during Windows startup can also be the cause. This type of error  will always require troubleshooting before Windows can start up normally.
  • Intermittent errors that appear randomly. These can be caused by an overheating processor, a defective memory system, a dying or  dead hard disk , or faulty software and device drivers. 
Solution :
These are some of the most common Stop Messages along with their cause and suggested resolution:


1. Stop Code: STOP 0x0000000A        
                         IRQL_NOT_LESS_EQUAL

Code Meaning : Faulty device drivers, or services from backup utilities or virus scanners

Recommended Resolution: Remove, disable or stop the offending drivers, backup utilities or anti-virus programs. Get updated
software from the manufacturer.

2.Stop Code: STOP 0x0000001E
                        KMODE_EXCEPTION_NOT_HANDLED
Code Meaning: Some driver files may be causing a problem.

Recommended Resolution: Remove, disable or update the driverfile listed in the error message. Verify if new hardware installation
is correct.

3.Stop Code: STOP 0x00000024
                       NTFS_FILE_SYSTEM
Code Meaning: Usually caused by disk corruption in the NTFS file system or third-party disk defragmenters.

Recommended Resolution: Use hard disk diagnostic software to verify that the hard disk is working. Remember to always Use
Microsoft-certified disk defragmenters.

4.Stop Code: STOP 0x0000002E
                       DATA_BUS_ERROR
Code Meaning: Caused by a parity error in the system memory. Almost always caused by hardware problemsa configuration
issue, defective hardware, or incompatible hardware.

Recommended Resolution: If physical RAM was recently added to the system, remove it and see if the error still occurs. If the error
persists, try disabling memory caching in the BIOS. Else remove, repair or reinstall the defective hardware.

5.Stop Code: STOP 0x00000050
                        PAGE_FAULT_IN_NONPAGED_AREA
Code Meaning : Caused when requested data is not found in memory; the system checks the page file, but the missing data is
I dentified as unable to be written to the page file

Recommended Resolution: Remove any newly-added hardware or run diagnostic software supplied by the manufacturer to check if
the component has failed. Install updated device drivers or roll back to a previous driver.

6.Stop Code: STOP 0x0000007B
                        INACCESSIBLE_BOOT_DEVICE

Code Meaning: Caused when Windows loses access to the system partition during the Startup process. This can be caused by: an
incorrect driver for a SCSI, RAID, or UDMA IDE controller;incorrect ARC path in the Boot.ini; or a failed boot device.

Recommended Resolution: Verify that the disk storage device is installed correctly and working. Reinstall or update the device
driver. Verify that the BIOS setting for the device is correct. Verify the integrity of the hard disk.

7.Stop Code: STOP 0x0000007F
                        UNEXPECTED_KERNEL_MODE_TRAP
Code Meaning: Caused when the CPU generates an error that the kernel does not catch. Usually hardware related especially RAM.
Can also be caused by CPU overclocking, or defective components on the motherboard.

Recommended Resolution:

1. Run the memory diagnostic to test RAM.

2. Restore over clocked settings to previous values.

3. Repair/replace the motherboard.

4. Disable sync negotiation in SCSI BIOS; check SCSI termination.


8.Stop Code: STOP 0x000000D1
                        DRIVER_IRQL_NOT_LESS_OR_EQUAL
Code Meaning: Occurs when the system attempts to access pageable memory at a process IRQL that is too high

Recommended Resolution: Very similar to STOP 0xA. Remove,disable or stop the offending drivers, backup utilities or anti-virus
programs. Get updated software from the manufacturer.

9.Stop Code: STOP 0xC000021A
                        STATUS_SYSTEM_PROCESS_TERMINATED
Code Meaning: Caused when the user-mode subsystem (Win logon or CSRSS) is fatally compromised and security cannot be
guaranteed. The most common causes are third-party applications or mismatched system files.

Recommended Resolution:

1. Remove, disable, or roll back any newly-installed device driver.

2. Uninstall any newly-installed software.

3. Use Windows-compatible backup/restore programs.

4. Restore full control permissions to the local SECURITY account on the system root folder by doing a fresh parallel installation of
Windows on a separate partition.
