If you have reason to believe that a DRIVER is faulty or not correctly working such as Sound or Video drivers etc... before posting and asking what to do try some of the following steps to troubleshoot the issues at hand.
Check to be sure you installed the Driver. “I know you may ask well that’s dumb, sadly I can’t count how many times I have seen this. Some people just do not know” How to do this and what to look for.
How to.
Anyone on Microsoft Windows 95, 98, and Windows ME can get to the Device Manager by clicking Start > Settings > Control Panel > System icon > and click the Device Manager tab.
Anyone on Microsoft Windows 2000 and XP may get to the Device Manager by clicking Start > Settings > Control Panel > System icon > Hardware tab > click the Device Manager Button.
Anyone who has a keyboard with the windows key may also quickly get to the system properties by pressing the “Windows key” + “Pause key” AT THE SAME TIME.
What to look for.
If your system declares its self “okay” you will only see a screen that looks like this.
This means all your drivers are correctly working.
However an issue still may exist but may not be a driver issue.
If you have any of the following “an exclamation mark, a red X, or an Other device.”
Here is what they mean,
Exclamation Mark - When a device has a yellow exclamation mark, this is an indication that the device is conflicting with another hardware device.
Red X - Indication that the device has been disabled, removed or that Windows is unable to locate the device.
Other Devices - Windows was unable to locate the drivers for the device and cannot determine the type of device being installed.
Each of the Device Manager Error codes can be found in this MS guild along with some recommendations that MS Suggests Device Manager Error codes
Another great idea to do is check for updates at the Manufactures website place you bought your PC so example, lets say you have a Dell you will need to visit www.dell.com find your PC’s model.
NOTE: Your model can be found in the front of the Tower Case or on the side or rear of your computer Depending on manufacture.
And if you have any after market hardware added to your manufactured PC you will need to consult that hardware’s website for drivers updates or patches.
Clearly I don’t think anyone who builds a custom PC will need to retain to this information there for I am excluding “Custom built PC’s”
If you have tried everything suggested and you are still experiencing an issue consulting one of the form EXPERTS here is the next thing you may consider or taking your PC to a local shop for hands on examination.
This concludes my quick guild to checking for driver functionality and how to solve slight issues such as being sure your drivers are correctly installed and or updated.
I hope this helps.
