How to Troubleshoot a Compaq Presario C700

For many years the Compaq name has been associated with business computers, but the Presario line of desktops and notebooks is widely used in the home environment as well. But no matter what type of Compaq PC you have or how that computer is used, it is important to have some basic troubleshooting skills. While new Compaq computers come with a warranty, when the warranty period on your Presario C700 is over, repairs can be quite costly. Knowing what to look out for and how to fix it can save you a lot of money.

      Click the "Device Manager" button to see a list of devices installed on your Presario PC. Click the plus sign next to each device and look for any yellow question marks or red exclamation points--these are indications that the hardware is not functioning properly.

      Right-click on the malfunctioning piece of hardware and choose "Update driver" from the menu. This will force the operating system to install an updated driver. Pay particular attention to the network adapter section of Device Manager--many Presario C700 models were prone to problems with the network adapter drivers. If you suddenly lose network or Internet connectivity this would be the first place to look.

      Turn your Presario C700 off and disconnect the power cord. Remove the retaining screws on the back of the case and take off the computer cover. Place a grounding strap around your wrist and snap the clip to the chassis of the PC. This will reduce the chances that static electricity will damage the computer.

      Locate the memory modules on the system motherboard and remove them one at a time. A bad memory module can cause a variety of symptoms, from a computer that simply runs slowly to one that refuses to boot. Flip back the retaining clips that hold the module in place and remove each module one at a time until you locate the faulty one.
