If any point in your life, you’ve experienced an inexplicable computer error or failure; you may have to figure the problem out via the process of ‘troubleshooting’. If you are considering training as an I.T technician, such as the A+ certification, or even just sick of failing to fix your computer, it is vital you learn the common problems that affect a computer’s functioning.
One of the most common errors is a ‘stop’ error or infamously known as the blue screen of death (BSOD). Apparently this problem can be hard to solve by turning the computer on and off and can usually only be resolved by viewing the stop code in order to understand what the problem exactly is. Stop codes identify a specific problem; hence each code (each has different number and letters) represents a particular error.
Stop codes can be found on the blue screen of death, however, since Windows’ systems restart after an error occurs, it can be somewhat troublesome to read the code. To overcome this, you will have to disable Windows’ automatic restart. Then, finally, you can read the code and begin to comprehend the problem.
Common codes include the STOP 0×00000002, which may be followed by the error ‘device_queue_not_busy’. The most likely cause for most codes is an error with hardware or device drivers, which are generally, resolved using a few simple steps.
First of all, reboot the computer as the blue screen of death may just vanish as if it never existed. The stop error can be a temporary issue due to unknown errors within the system. If this fails, next you need to troubleshoot.
With this sort of problem, you have to ask yourself what it may have been caused by – could it be new a new program? New hardware? Updates? If there has been recent activity or changes, simply undo it and test for the stop error. To undo the problem, you can use system restore, reverse any updates on driver devices, and starting up with last known good configuration, which will undo registry and driver changes. Which method you choose will depend on the problem. It may be also be caused by out of date driver issues, so updating them may in fact solve the issue.
If still no solution, check that there is still enough space on your system partition, which holds Windows. Lack of memory can apparently cause stop errors. Check also that your computer is virus free, as some particularly nasty viruses can contaminate the boot master and the boot area.
One other cause could be loose or not properly installed components. You will need to check that everything is correctly installed and may have to reseat components, and then complete another BSOD check. Next performing diagnostics on all testable hardware will eradicate some hardware causes or even find the root cause. If your system fails the test, the hardware or memory may need replacing.
If the previous test has no fruitful results, start your computer with the minimum system running requirements. If no stop error screen appears, it’s likely to be one of the other programs.
Troubleshooting can be a lengthy process and can take awhile to solve what may be a small problem. Troubleshooting is a vital part of I.T training in I.T technician certifications, such as the A+ certification.
