Troubleshooting Computer Hardware Appendix B
Axia College Material Appendix B Troubleshooting Computer Hardware In this worksheet, you must identify solutions for three separate selective selective information processor stickyware businesss. For apiece solution, you must prepare an answer of at least 150 manner of speaking within each of the following serve well boxes. Part One Troubleshooting a Failed Boot trouble The computer fails to flush. Details wrongful conduct messages and beeps occur during motive On Self Test ( get off) startup.Note You have non recently upgraded the retrospection. marvel What are four possible sources for the demerit messages, and how do you troubleshoot them? Hint You whitethorn look at Figure 3-45 in A+ Guide to Managing & Maintaining Your PC. Answer Four possible problems that could be indicated by error messages and beeps on POST include a dead CMOS onslaught, hard crowd blow, video bankers bill problem or storehouse failure.These problems are also listed in the baf fle of the easiest to the most difficult to fix. CMOS Battery Power on the computer and turn on the required key (such as F2) that is required to enter the BIOS program. Upon entering the BIOS sack a none of the settings, especi on the wholey the date and time. If they are set at some point in the past its plausibly that the battery could be dead. Also, set the time, turn the PC off, and then reboot. If the time has specify then the battery is likely dead and should be replaced. Hard hale failure If upon boot the screen indicates a message such as No Operating System found its likely the hard drive has a problem or is not being recognized. potato rubbish the BIOS to see if the correct drive type is listed. If not its likely the hard drive has a problem and a diagnostic gumshoe provided by the manufacturer would be the best solution. Video posting failures If the computer has no video output check the connections and try the video poster in an other(prenomin al) expansion slot if possible. You can also try removing and reinserting the card to see if the machine impart recognize it. Memory Error typically a series of beeps can indicate a problem here(predicate) or some type of error message relating to a failure to read at a particular address. You can try removing the repositing board facultys 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 Two Troubleshooting Memory Problem Error messages indicate a problem with memory. Symptom Recurring error messages intimately illegal operations and/or general protection faults appear during pattern operation. Note You have not recently upgraded the memory. incertitude How might memory be the cause of this problem? How would you go about testing the memory? If you use a testing utility and determine that memory is not the problem, what are three other things you would suspect to be the source of the problem? Describe what you would do to eliminate each possible source. Answer If in that respect is a problem with the memory its likely only at a certain location within the memory module itself and not the holy module. Since information is randomly written t different addresses in memory the computer may not always indicate an error message. Truly random error messages indicating a problem with illegal operations would likely be a good indicator of the problem if no other symptoms exist. There are many tools available for testing memory. These tools will attempt to read/write to all locations on the memory chip to find out if any particular address in the memory chip is failing. some other 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 didactics from a particular program or a problem with the OS installation.If the memory is not the problem then additional troubleshooting is required including determination out if the problem only occurs in a certain program. It could be an OS discern if its when the computer is booted or fill up down. Troubleshooting a video card problem may be more difficult and a different video card could be attempt Part Three Troubleshooting a Hard Drive problem Problem The computer shuts down immediately after startup. Symptom When you turn on the computer, the lights on the front panel light up and you hear the cull out 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 recovering data from your hard drive? List the major steps you must arrest to recover da ta. Answer The first step would be to attempt to boot the computer using a boot disk that contains core operating(a) 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 offend location can be erased to prevent the problem. Each of these steps involves run a 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 workings OS. This may provide the opportunity to retrieve 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 used or the drive should be plac ed into another computer. A recovery 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.
