Computer Repair - Diagnose the fault and repair it - the computer repair guy
Beyond boot disks and other backup routines, it is crucial to know how to identify a failure or a PC
operating system. The biggest problem in computing, it is not so much to repair a PC plant, but rather to
know from where the disagreeable phenomenon.
We have therefore decided to present the case of failure the most frequent form of case study to
explain how the repair. Here's how to diagnose the fault with the different methods that we develop in
this articles, then follow the guide for a micro computer in full form.
First case: Windows can not manually start or malfunctioning devices: Safe Mode failure
It is certainly the routine rescue the most common. Indeed, this kind of system failure often occurs after
installing a new device or new software. Upon restart, Windows can not find his small programs and can
not start properly. The failing is probably a faulty device driver. Turn off everything. Restart by
repeatedly pressing the F8 key on your keyboard when your computer has finished its pre-test. This
command will bring you a custom startup menu. Several options are available.
3 - Start in Safe Mode. " This command tells Windows to be limited to the minimum load (16-color
display, graphics card by default, drivers required ...) to work. His sole mission? Start at any price so you
can identify the source of your power.
Once the system is running, open the Control Panel (from Settings in the Start menu), then click on
System and then Device Manager. Search exclamation points to a device. They indicate that the driver is
broken and may crash Windows.
On the right-click on that device, choose Properties, and try to reinstall the driver. If this is new
hardware, sound card or other device that you just add, try to remove it by right-clicking on the device
and select Delete.
Attention never delete a component of the motherboard! Then turn off your computer and then
physically remove your drive and try to reboot. If all goes well, go to the manufacturer's website to find
the last driver that corrects the fault and attempt a reinstall. Note that for small faults, the simple act of
starting in safe mode before reboot in normal mode can resolve the failure.
Second case: Failed to safe mode, the confirmation step
If the first method does not work, the source of the problem can be located at the windows himself and
loading vxd or dll files. In this case, you must undertake a more tedious. As before, try to start and press
the F8 key repeatedly (or del) before loading Windows. This time, choose the option
4-Step Confirmation (see figure above). It is this time to identify the driver refuses to load. In this mode,
it is necessary to systematically start of each file to yes (Y / N) to note on a piece of paper the name of
file or driver that is problematic. Try to answer Yes until you encounter a problem. You'll certainly get a
file name that must be restored cabalistic since the original Windows CD or the Internet. Reboot into
safe mode and find the normal location of the file and replace it with the new biensur with the same
extensions, same names etc.. Overwrite the old and the new Restart. Repeat as many times as there are
Last event: Restore the last known configuration
The last good configuration is yet another method to restore Windows to a previous state when the
apparation a serious problem. The option is useful when course driver or a problem caused
confuguration or Windows registry. To see if this option can help you, follow these steps.
In the Start, select Shut Down, then Restart, press F8 as the beginning of the boot. In the advanced
options menu of Windows, select Last Known Good Configuration.
Important: How to choose the right method? If Windows opens, but has problems, use the normal
mode and run System Restore. If Windows does not open, use the last known good configuration, if it
does not work, try to open Windows in Safe Mode, then run System Restore. If the armory is not, then it
must go through the BIOS to force the boot with the Windows installation CD.
