Troubleshooting Computer Hardware Appendix B

Axia College Material Appendix B Troubleshooting reckoner securew ar In this worksheet, you mustiness identify solutions for three separate calculating elevator car computing device vexedware worrys. For individu wholey solution, you must prepare an firmness of at least 150 haggle within each of the following serve boxes. Part One Troubleshooting a Failed burster Problem The computing machine fails to arouse. Details computer defect messages and beeps occur during personnel On ego Test (POST) startup.Note You arrive at non of late upgraded the retention. Question What are four affirmable 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 quadruplet possible lines that could be indicated by fault messages and beeps on POST include a dead CMOS assault and battery, hard beat back trial, icon card puzzle or store failure.These puzzle s are as well as listed in the ramble of the easiest to the most difficult to fix. CMOS Battery Power on the computer and press the compulsory key (such(prenominal) as F2) that is required to tape the BIOS program. Upon entering the BIOS make a flavour of the make up ones mindtings, especially the date and cartridge clip. If they are set at some point in the past its promising that the battery could be dead. Also, set the time, turn the PC off, and thusly re spate. If the time has reset then the battery is likely dead and should be re situated. Hard subscribe failure If upon quiver the screen indicates a message such as No Operating arranging found its likely the hard elbow grease has a riddle or is not being recognized. Check the BIOS to square up if the correct involve type is listed. If not its likely the hard mystify has a problem and a symptomatic tool provided by the manufacturer would be the best solution. Video card failures If the computer has no idiot box protrudeput score the connections and undertake the video card in an other(a) slot if possible. You passel also try removing and reinserting the card to see if the machine impart recognize it. fund break Typically a series of beeps nominate indicate a problem present or some type of error message relating to a failure to direct at a point verbalize. You trick try removing the warehousing facultys one or two at a time depending on the configuration and try booting with the warehousing in a divergent slot or without part of the retrospect to try and deduce which memory module whitethorn have failed. Part Two Troubleshooting Memory Problem Error messages indicate a problem with memory. emblem Recurring error messages intimately illegal operations and/or general protection faults appear during formula operation. Note You have not belatedly upgraded the memory. Question How might memory be th e 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 at that place is a problem with the memory its likely only at a certain(prenominal) location within the memory module itself and not the entire module. Since culture is haphazard written t diametric addresses in memory the computer may not everlastingly indicate an error message. real 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 approach to read/write to all locations on the memory chip to detect out if any particular address in the memory chip is failing. other possible way to troubleshoot would be to try the m emory 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 speculative 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 determination out if the problem only occurs in a certain program. It could be an OS issue if its when the computer is boot 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 startup. Symptom When you turn on the computer, the lights on the ride panel light up and you attend the fan spin for a moment, tho then it shuts down immediately. You have imperative data on the hard drive that is not indorse up. Question What is the quickest and easiest way to solve the most imperative problem, which is withholding data from your hard drive? List the major steps you must complete to recover data. Answer The starting time step would be to attempt to boot the computer using a boot disk that contains core operating remains files and then running a read 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 prevent the problem. Each of these steps involves risk of infection 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 notice the critical data by now copying it to the other hard drive or other storage media. If both of the above attempts are no t in(predicate) then there are programs that attempt to recover data from the hard drive. A boot disk should be employ or the drive should be placed into another computer. A retrieval 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 requisite to try and recover the data if possible.
