Troubleshooting Your Computer

If you’re going to be building computers, adding devices to your computer, altering BIOS settings, or just installing and deleting programs on your computer, then you’ll want to learn the basics of troubleshooting. You might notice that I didn’t say computer troubleshooting. That is because troubleshooting is an independent skill. I learned to troubleshoot as an electronic technician. And most of those same techniques work fine for troubleshooting computers.


Troubleshooting is really a kind of detective work. If you notice, the TV detectives spend a lot of time asking questions and thinking over the facts. And that is where a good troubleshooter starts, asking questions, not with tearing apart their computer, swapping components, or running diagnostics programs.


My intent here isn’t to give you heavy technical troubleshooting instructions, but to provide you with common sense techniques that will likely save you a lot of time and trouble if you follow them.


Take note: I am assuming a basic to intermediate knowledge on the part of the computer user for this article. In other words, that you either build computers or add components to it, like hard drives or CD drives. I also assume you have a basic understanding of the boot process. Finally, I assume you know basic electrical safety rules.


A Typical Scenario


Let’s say one evening you turn on your computer and it starts, seems to boot fine, but stops dead at the point it should start loading Windows. What now? You panic of course. Like most of us you haven’t saved copies of your most important documents for months. And since Windows isn’t loading from the hard drive, you “logically” assume there is a serious problem with the hard drive. It must be physically broken or the data is scrambled.


Since you’re in panic mode you tear the hard drive out of your other working computer and try to boot the first computer. The same thing happens, it stops at the point of loading Windows. What a relief, at least the problem isn’t with the hard drive, your data is safe – there is probably a fault with the motherboard in the first computer.


To make sure, you test the hard drive from your first computer (the one that wouldn’t load Windows) in your second computer, it works fine. That confirms it, there is a problem with the motherboard on the first computer. Probably the hard drive controller, you think, being the expert.

    I can’t connect to the internet on my home computer. there’s a symbol at the bottom in the right, that when I click on it says cable unplugged I cant’ find this cable.

    • Darryl

      check your network cable …make sure cable is hooked into your network card or modem on rear of pc… and that other end is secured into a Modem or router or telephone jack…then reboot gl

    • http://www.cbral.net shekhar gupta

      check your internet cable . first check your modem ya wifi i dont know your connection is wired ya wirless. full service are there for internet service provider. if you checked you internet staus then you check your cable and lan . cable jack also check. easy way to check you lan you hire to lan connector.
      i think u solve this problem.

    Here’s a strange one.
    Every time I power up my computer it takes two attempts. The first try runs at least through the blinking lights on the CD player. The power supply comes on, the CD is checked for boot, and then the whole thing just sits there – blank screen (no initialization whatsoever) with the PS fan quietly whirring.
    Then,
    I simply hit the reset (warm reboot) and it starts up normally – every time!
    I haven’t a clue. If anyone out there can send me in the right direction I will become a one man walking marketing phenomena for this site.
    Fully puzzled….

    • AE Wilson

      What hardware do u have in there? the reason why i ask is that it sounds a little like your power supply might not be powerful enough to power your rig properly.

  • Bill Jordan

    My 2 year old, wellcared fo Acer Notebok 5100 has been running slowly so I transfered all my info onto an exterior harddrive, then I inserted the disk that came with the computer for reformatting (I’m not that computer savvy but I think you know the disks I mean that redo everything that came with you computer when you bought it.
    It only will get to 5% completed until it goes dark again. I have tried taking the battery out and putting it back in as someone told me that sometimes helps. I have it plugged into wall socket,cords seem fine. Any suggestions? If it is motherboard problem, how do I know which one to get? I’ve tried putting AMD turion64 MK36 into various parts searches and no results.

    • Darryl

      clean and retry cd or try another os cd and ….gl

    • Diane

      Thanks for your reply. I ended up deciding that it might be overheating so I put it in the freezer for 15 minutes, then left it in the freezer while I ran the restore disk. Worked like a charm. It installed all the way, but then I had to wonder why it was overheating if the fan was working. I took that back plate off……and yikes the fan was FULL of fuzz. (I don’t even put my lap top on my lap!) I carefully cleaned the fuzz out, had enough to make myself a poodle. I then covered the workings of the computer with a piece of paper and taped it so no dust could get in. I blew the fan area clean with an aerosal air blower. My computer has never worked so GOOD !

      • Darryl

        hmmmmmm thats risky in the freezer..happy u didnt ruin a circuit….mines heat up too a 4 month old Acer….i,ll check now regular the fans air vent…but no freezer…that can ruin the poor thing…ty for the reply

        • Diane

          Didn’t leave it in there like a rump roast…just long enough to cool it and then to see if it would load up the disk (15 minutes) which told me the problem actually was overheating. The relative humidity is probably high in the freezer but probably no higher than some gulf coast states like Texas. So in that small amount of time I doubt it got below 40 degrees which is the temperature around here outside the freezer every morning.

    After booting up my system works normal for the first 10 minutes and then shuts down on its own. I have to reboot the system and then it works fine the rest of the day. This has happened every day for 3 weeks. Any ideas.

    • Darryl

      i would advise a system restore…hit start button to accessories….then click on system tools and find restore….back it up about a month…..and it will reboot….gl

  • lello01

  • Darryl

    Your Computer cant load win xp…damaged some how…hate to say it but u need to reinstall windows..u also said it flashes the blue screen of death….thats definitly a sign of a crashed hard drive….u can try resoring with a windows boot cd….but reinstall is more perfered a reinstall will also let u know if u have bad sectors on Hard Drive GL

    • Elie

      oh ok thanks… so if resintalling doesnt work, would the hard drive be changed?

  • Darrryl

    I have a laptop (IBM ThinkPad), running windows XP Pro service pak 3. Every time I try to download software the computer shuts down, ie., roxio, belkin wireless, adobe.

    Hi, I have a problem that’s stumping me. My computer boots normally, and shows the WinXP load screen, but at the point where my background pic should come up and/or the Windows login dialog should start, both my screens go blank.

    I can load Windows in safe mode with no display problems, which leads me to believe it’s not a video card problem. Can anybody advise me?

    - Jack

    My PC forgets the DAY< DATE AND TIME after the power has been off for the night. Something about BIOS error?
    What is the problem and will it cost big bucks to fix?

  • Byrdie

    I have a IBM thinkpad. My son was using it and every few minutes it would pop up that a virus had infected the system. Now It will start up and we are able to choose the user and then it will not load the desktop. SO I tried to work in safemode and it will not load. Is there something we can do or what can we do.

    • http://www.cbral.net shekhar gupta

    we recently installed/upgraded our pc protection with NORTON 2010, but now the pc is ok in itself, but when we login to facebook we can’t get our homepages to load, but we can get to our wall pages, also when we are on youtube and things like that there are no videos to watch it’s there but it not showing the video itself, and the pc will no longer display the sidebar on our pc homepage…..is norton blocking all of this………..or is it just a coincidence, and the cause is something else????….thx for your help.

    My computer crashed and I ordered a new recovery disc. I ordered win vista 32 bit, but later, checking on the HP site, I am now under the impression that I should have ordered 64 bit. After installing, I try playing Oblivion. The mouse is eratic and the game is constatntly acting as if it is trying to catch up. Oblivion played on this laptop fine, smooth and quick before I loaded Vista Home Premium 32 bit. HP support says that the 32 bit is not the problem. Help!

  • Bob

    Problem solved.

    hi
    I have a serious problem. I use an acer aspire 3000 laptop. Since yesterday, when i open it, it loads windows(xp) then freezes for 1-2 min, showing the desktop image, until the task bar and desktop icons are shown, but then i cannot use the keyboard and touchpad. If i try to shut it down, it will freeze! I used antivirus to scan and found nothing. I reinstalled windows and i still got the same problem. In safe mode, everything is fine though.
    Can someone help? Thanks

    Trying to help a friend – she was trying to post on Craigslist when suddenly the computer just crashed.. When she turned it on again, it went to a porn site and wouldn’t let her go past it. After re-booting again, she can get to the internet – kind of, but when a website is typed in, like google. com, it tells her it isn’t safe and takes her to a website to buy anti-virus software. We tried a bunch of different websites that we know to be safe, but we always end up at the website to buy anti-virus software. How can we solve this?
