Troubleshooting Computer Hardware Appendix B
Axia College Material Appendix B Troubleshooting Computer ruffianlywargon In this worksheet, you must identify solutions for three ruin data processor with child(p)w be conundrums. For only(prenominal) solution, you must prepare an answer of at least 150 words in spite of appearance each of the following declaration boxes. Part One Troubleshooting a Failed Boot Problem The computer fails to surge. lucubrate Error messages and beeps occur during mogul On Self Test (POST) startup.Note You deal not of late upgraded the retrospection. Question What are four possible sources for the wrongful conduct messages, and how do you troubleshoot them? Hint You may look at Figure 3-45 in A+ Guide to Managing &038 Maintaining Your PC. Answer Four possible tasks that could be presentd by hallucination messages and beeps on POST include a gone CMOS battery, problematical compel failure, exposure card problem or memory failure.These problems are also listed in the soun d out of the easiest to the closely difficult to fix. CMOS Battery Power on the computer and press the demand key (such as F2) that is required to enter the BIOS program. Upon entering the BIOS make a note of the settings, especially the catch and time. If they are set at any(prenominal) point in the onetime(prenominal) its likely that the battery could be dead. Also, set the time, turn the PC off, and whence reboot. If the time has reset then the battery is likely dead and should be replaced. Hard drive failure If upon boot the screen indicates a message such as No Operating System embed its likely the sonorous drive has a problem or is not being fill outd. Check the BIOS to see if the correct drive slip is listed. If not its likely the hard drive has a problem and a diagnostic tool provided by the manufacturer would be the best(p) solution. Video card failures If the computer has no video output run down the connections and demonstrate the video card in another slot if possible. You dope also look for removing and reinserting the card to see if the machine will recognize it. Memory Error Typically a series of beeps can indicate a problem here or some type of error message relating to a failure to read at a crabby address. You can try removing the memory modules one or two at a time depending on the configuration and try booting with the memory in a different slot or without part of the memory to try and deduce which memory module may have failed. Part ii Troubleshooting Memory Problem Error messages indicate a problem with memory. indication Recurring error messages about illegal operations and/or full general protection faults appear during normal operation. Note You have not recently upgraded the memory. Question How might memory be the cause of this problem? How would you go about testing the memory? If you use a testing public-service corporation and determine th at memory is not the problem, what are three other things you would doubt to be the source of the problem? Describe what you would do to eliminate each possible source. Answer If there is a problem with the memory its likely only at a certain location within the memory module itself and not the entire module. Since randomness is randomly write t different addresses in memory the computer may not al meanss indicate an error message. Truly random error messages indicating a problem with illegal operations would likely be a rock-steady indicator of the problem if no other symptoms exist. There are legion(predicate) tools available for testing memory. These tools will try on to read/write to all locations on the memory chip to find out if any limited address in the memory chip is failing. Another possible way to troubleshoot would be to try the memory in a different computer. If a memory test concludes that there is not a problem with the memory then likely causes could be the memory in the video card, a bad program instruction from a particular program or a problem with the OS installation.If the memory is not the problem then additional troubleshooting is required including finding out if the problem only occurs in a certain program. It could be an OS issue if its when the computer is booted or shut down. Troubleshooting a video card problem may be more difficult and a different video card could be tried Part Three Troubleshooting a Hard Drive problem Problem The computer shuts down immediately after(prenominal) startup. Symptom When you turn on the computer, the uncontaminatings on the front panel light up and you hear the fan spin for a moment, but then it shuts down immediately. You have urgent data on the hard drive that is not backed up. Question What is the quickest and easiest way to solve the most urgent problem, which is happening data from your hard drive? List the major(ip) whole tones you must complete to recove r data. Answer The first step would be to attempt to boot the computer using a boot disk that contains core operating system files and then running a scan of the hard drive to find out where the errors exist.Sometimes these errors can be fixed or the offending location can be erased to impede the problem. Each of these steps involves risk and if this is for a consumer they should be informed of the risk. If a scan of the disk finds the issue and is repaired the computer should be booted and the information backed up immediately. Another option would be to put the hard drive in another computer as the non-OS drive and attempt to access it from a working OS. This may provide the opportunity to go back the critical data by directly copying it to the other hard drive or other storage media. If both of the above attempts are not successful then there are programs that attempt to recover data from the hard drive. A boot disk should be utilise or the drive should be placed into another computer. A convalescence tools can scan the entire contents of the drive and may be able to recover all or at least some of the files if they are not damaged. If the information is highly critical it can be sent to a data recovery professional in order to have the data extracted. While this is not always successful depending on the type of failure its at least necessary to try and recover the data if possible.
