Windows XP and Windows Me offer System Restore, which lets you roll back your computer to an earlier configuration. By default, Windows creates periodic checkpoints either on a scheduled basis or when you make changes to the system. In case of a problem, the System Restore wizard lets you step back to a prior state when your system was running better; it won't delete data files, but will restore system files and Registry entries. To get to the System Restore wizard, go to Start | Accessories | System Tools | System Restore.
Access crash logs.When a crash occurs, an app called Dr. Watson saves info about your memory and configuration to a crash log file. In Windows XP, the default location is C:\Documents and Settings\All Users\Application Data\Microsoft\Dr Watson. The crash log is a text file called Drwtsn32.log, which can be read in Notepad or sent via e-mail to a tech-support person. Dr. Watson can also create a crash dump, which contains similar information but is readable only by a debugging utility. If you have to call for support, this may be helpful in a quicker diagnosis.
Know your systemResolving a problem over the phone requires a series of questions, often having to do with the specific hardware, operating system, and software you're using. Know the model numbers for all your hardware. You can access CPU and memory info by selecting Control Panel | System. Choose Hardware | Device Manager for information about other devices such as your sound and graphics cards.
Try to remember any new software, no matter how small or insignificant, that you've installed or noticed lately. It can also help to jot down any services running in the background. To access a list of what is running on your Windows XP system, press Ctrl-Alt-Del and select Task Manager. You can also get very detailed info from Start | All Programs | Accessories | System Tools | System Information.
Roll back driversSometimes updating your drivers can backfire. If something breaks when you update a driver, you should use the Driver Rollback utility, which works much like System Restore but only on a specific device driver.
To roll back to a previous driver, open the device manager (Control Panel | System | Hardware | Device Manager), select the device with the driver you want to roll back, right-click, and open its Properties. Under the Drivers tab, you can update, roll back, or uninstall the driver.
Check your connectionsThis may sound too obvious, but check all the cables to make sure they are plugged in securely. Don't ignore this step. USB, printer, and serial cables have a way of working themselves loose and causing problems.
Update your systemMake sure that you are using the latest drivers for your hardware--and that you've installed all the Windows Updates--and you are properly running both antivirus and ad ware blocking applications--and check for updates to any applications you use, especially any that seem to be related to your current computer problem.
Microsoft is always updating Windows with minor patches and bug fixes. Go to www.tnics.com and click on the Windows Update icon and scan your system and install any critical updates available.
RebootWindows sometimes gets into a confused state, and by simply rebooting you can clear the memory and everything will work fine again. If you're having a problem connecting to the Internet using a dialup connection, often times, a restart fixes the connection issue. If you have DSL and also have a router, reset BOTH the DSL modem and router by unplugging and rebooting them.
Back up your dataBefore you start following directions over the phone and tearing your system apart, make sure you have a backup of all your important documents, e-mail, and other data. Although many fixes will be as simple as downloading a new driver, you'll be glad you have a backup if you find yourself reinstalling the OS. You should also have your original CDs around in case you need to reinstall apps.
Check for IRQ conflicts.IRQs (interrupt requests) are hardware connections that the CPU uses to receive signals from a device. If two devices are using the same IRQ, they can conflict with each other and cause crashes. In most cases, IRQs are assigned automatically when the PC boots. Occasionally, a device may want a specific IRQ, even though this causes a conflict with another device.
To view a device's IRQ listings, open Start | Control Panel | System and select Device Manager. Find the device (sound card, modem, whatever); right-click on it and select Properties, and click the Resources tab. You will see a list of resources: I/O range, memory range, and IRQ. Some devices let you configure these; other configurations are automatic. You will also see the conflicting-device list. Note the IRQ and any conflicting devices. Sometimes swapping two boards or moving one farther away will fix an IRQ conflict.
Narrow down the problemTry to isolate when and where the problem happens. If, for example, you discover your printer isn't working from Word, check to see whether it works from Wordpad or another program. Many times the problem is just a wrong setting.
