Required Tools for PC Repair?

kennethrona asks: "I seem to be spending a lot of my time installing friends' WiFi access points, replacing power supplies, hard disks, blocking ports, installing software, etc. I can usually find any of the software I need on-line, but am thinking about putting together a "toolkit" for PC repair. What tools, both hardware and software, does the community think are essential for PC repair? Bonus points for free software (I always install a free firewall and spyware checker). Also, keep in mind that most folks are running Windows."

      > A philips screwdriver is always needed.

      Always. A slatted screwdriver also comes in handy sometimes. If
      you have to work with Compaq systems, you'll also want a set of
      six-pointed-star ("Torx") bits, including a couple of the ones with
      the hole in the middle ("Security Tee Star" -- you NEED these,
      because the only _other_ way to get those screws out is with a
      drill; Compaq is evil) and a spare NIC, because Compaq systems tend
      to use a NIC that Windows will not recognise on install, and while
      the OEM system has the drivers you need, if you have to reinstall
      for any reason it can be painful trying to figure out which drivers
      you need -- especially for Deskpro models, which don't have the
      exact model number _anywhere_ on them. A spare NIC, worth $10,
      can save you hours of pain.

      I also keep around a tray with multiple little compartments in it,
      for screws; very handy. A spare IDE cable might be no bad thing too.

      One of the very best things you can have is a complete working
      system (preferably, a multiboot system). One of my favourite
      tricks is to pull the HD out of a non-working system, and put it
      in a working system as slave, so I can mount the drive and look at
      it. This is similar in principle to the Knoppix idea, but it has
      the additional benefit of isolating the hard drive from the rest
      of the system hardware.

      Oh, and a pair of needlenose pliers comes in handy for an
      astonishing variety of things. They fit certain types of screws
      that no ordinary screwdriver can manage, or can be used on the
      outside of the screw head in some cases. They're great for
      retrieving things (jumpers, screws, ...) that have fallen into
      places they shouldn't have. They have other uses as well, and
      if nothing else you can fidget with them while you think.

      Oh, and: you need a set of boot floppies, one for each major
      version of Windows, containing the following:
      * FDISK, SYS, FORMAT, and SCANDISK
      * A text editor you can use in an emergency.
      * REGEDIT (Know how to use this in command-prompt mode.)
      * An ATAPI CD-ROM driver general enough to work with most
      ATAPI drives. The Mitsumi one has worked for me.
      * MSCDEX
      * DEBUG
      * A hex editor, if you're not really comfortable with DEBUG.
      (You still need DEBUG though, for other things.)
      * A third-party boot loader that can install from the
      command prompt. BOSS for example.

      It's also good to have pkzip (and pkunzip), preferably the Win32
      console version, on floppy. These don't have to be on each boot
      floppy, just have them someplace, and a box of blank floppies.
      Sometimes you have to get manufacturers' drivers for a NIC or
      modem before you can get internet connectivity working, which
      means using another computer to download them, and they can be
      too big to fit on one floppy. The span-disks feature will get
      you around this problem. If you don't have it, or some equivalent
      compression and chunking solution, the other way out involves
      moving the hard drive over to the system that works (as a slave
      drive), depositing the files on it, and then putting it back where
      it goes. PKZip can save you from that sometimes, especially if
      you're dealing with a SoftPAQ that comes to 2MB or so; PKZip will
      fit that on two floppies for you.

      I also second the Knoppix suggestion. It isn't obvious at
      first glance, but Knoppix comes with mkdosfs (_very_ handy
      when the Windows CD has FORMAT embedded in a CAB and you have
      no filesystem to extract onto) and dosfsck (which with the -v
      flag gives better information than scandisk). Plus of course
      the Linux version of fdisk, which is somewhat better than the
      Windows version, and a decent text editor[1], and other things
      that can come in handy. And if it recognises your NIC, which
      in many cases it will, you can use this in lieu of the floppy
      solution to get NIC/modem drivers downloaded.

      [1] By "a decent text editor" I of course mean Emacs.

    Here's a few suggestions from my toolkit that I've put together over the years. I might work on anything from a Sun server to a Wintel or Mac so the tools are pretty generic.

    A power screwdriver. Most PCs have a large number of screws and doing them all by hand is (literally) a pain. I like the Milwaukee 2.4-Volt 2-Speed Cordless Screwdriver -- it's more expensive than some but is a quality tool that'll last. Get several extra batteries and an extra-long driver bit for easier access to motherboard screws.

    A set of nut drivers. These are screwdrivers for nuts, especially those little nut-screws on the back of the PC that hold the serial and video connectors on.

    A multimeter. Useful for all sorts of things from checking power at the outlet to grounding. Skip past the Wal-Mart cheapies and get a quality instrument like a Fluke.

    A set of ball-drivers. These are hex (a.k.a. Allen head) driver tools with a ball on the end so you can work at an angle.

    Torx drivers. Handy for working on laptops or newer machines. When you need it you need it -- no other tool will work.

    A DOS boot disk.

    An assortment of cables: a normal Ethernet, a cross-over, IDE, Floppy, USB, and serial. If you work on Unix or Linux servers or routers you might need to be able to hook up a serial terminal connection. I also like to have a set of extension cables for keyboard, mouse, and video for hooking up to equipment on racks.

    Several extra PC power cords.

    A cordless soldering iron (and the knowledge to use it). Not used very often but you never know...

    And, last, a book: "Upgrading and Repairing PCs" by Scott Mueller. This books is an amazing resource -- it'll tell you the pin-outs for everything from an ATX power supply to an IDE hard drive. It's handy to have when working with old or odd hardware.

    • It's also a good idea to keep a known-good network card handy along with driver disks.
    • Get a good DOS bootdisk. Try to get one that will let you mount SMB shares from DOS.
    • I seem to recall utils to let you read NTFS from DOS too, so try to get that on a disk or CD.
    • Copies of Norton Ghost and Parition Magic can come in handy sometimes.
    • Is there a way to write to CD-R from DOS? Or maybe Knoppix will work for that. Might be useful for backing up stuff before major surgery.
    • Heck, CD-R drives are pretty cheap now ($50-60, I think), so bring one along if you want a very complete kit. Or maybe just pack a cheap 30GB hard drive (I recommend you keep it at 30GB or less so it will work with older BIOSes).
    • Knoppix and Memtest86 (as others have mentioned) are very good. Tomsrtbt is also good.
    • Pack some zip-ties for making wires and cables neat. And bring something to cut out old ties.
    • Bring a paper clip for ejecting stuck CDs.

    • A pair of long, thin "pliers" that lock tight when you close them for gripping things. I forget the name, but they almost look like a medical instrument for clamping veins and such.
    • IDE cable, floppy cable, phone cable, ethernet cable. Extra screws of the normal type for computer cases. Extra jumpers.
    • A kit to mount a 3.5-inch drive in a 5.25-inch bay.
    • I think you can fit the install files for win95/98/Me all on one CD, so burn one and keep it handy for when windows demands the install CD for drivers.
    • It might also be a good idea to burn all the service packs and bug fixes you can find for old versions of windows. Include the latest version of IE and DirectX.

    • Partition Magic - Being able to shrink a partition just to be able to make another partition and do a clean OS install is invaluable.
    • Norton Ghost - The best in drive imaging.
    • CD with DOS boot floppy images (and some spare floppy disks stuck in the back) - You will need dos floppies to flash most bioses.
    • AV software - There are free AV scanners out there.
    • AntiSpyware software - Make machines run cleaner/faster.
    • filemon, regmon, etc - Small apps to figure out what applications are doing what to the system.
    • memtest86, burncpu - memory tester and cpu heat tester - keep images on a CD and spare floppies to dd them to.
    • GNU software disk - Latest stable releases of OpenOffice, Mozilla, CDex, etc for obvious reasons (e.g. "What can I do to stop pop ups while browsing? How can I write papers? How do I make mp3s?")
    • Free proprietary software people would be interested in - For example, Trillian.
    • CD copies of any legitimate OS CDs or utility CDs you own - Never, ever take the actual CD with you, it will be destroyed sooner or later. Make copies.
    • CD of windows updates and patches - Many people have 56k connections - you don't want to wait for the downloads.
    • CD of virus definition updates for common AV software - Again, you don't want to wait for software to update over 56k connections.
    • CD or reference materials - I find that a good set of hardware documentation works wonders. Of course, you can always use dead-tree format, but a CD is a lot more compact.

    Now, the tools:

    • A phillips screwdriver.
    • A flat head screwdriver.
    • A collection of nut drivers, good for badly stripped screws.
    • A collect of torx head screwdrivers for those damn Compaqs!
    • A collection of small phillips and flat head screwdrivers - useful for laptops and the occasional rewiring of LED and USB connectors (use the smallest flathead screwdriver to pry up the tab, slide the metal wire out of the connector, then push the wire into another connector.
    • Needle nose pliers.
    • Tweezers.
    • Bright flashlight.
    • Small container of common computer screws.
    • Container of compressed air.
    • Bandaids (some [usually cheap] computer cases have sharp edges).
    • Cable ties.
    • Some people suggest a small dental mirror as well, and a screw retriever - I've never found either to be that useful though. :)
    • Digital multimeter.
    • Outlet polarity and ground tester.
    • Small tablet and pen for notes.

    Now, replacement parts to be able to swap in and out:

    • A run of a mill ethernet card (ne2000 compatible or common 3com card seems to work best - try to get one that is DOS, Novell, Windows and Linux compatible)
    • A boring soundblaster sound card (cheap soundblasters are far from being the best cards out there, but they tend to be well supported by OSes)
    • 33.6 or 56k hardware modem - you can find the 33.6k modems dirt cheap used, but the 56k hardware modems will run you $50 or so new - either works well for testing out bad internet connections.
    • Known good PCI video adapter.
    • Working floppy, and 80-Wire IDE cable.
