If you just built the machine and installed windows afterwords it will have no default drivers.
Lets say for example you just built a lga 2011 machine with this.

After that you have no drivers except for what windows will provide which is the wrong ones to begin with.

Now you go by asrock after looking up your mobo model number on the box.

First you will want your chipset drivers which is vital to the system to keep it running stable.
Then you want you lan card drivers so you can use your cable/dsl internet and adjust the settings from the utility.
Then you want sound card drivers so you arent relying on windows general drivers to play any sounds in crap quality.

This is how you will go about it, if you bought a prebuilt computer just remove the crap/bloatware from the machine.
Install a better AV/Malware suite other than norton or mcafee which still doesn't do much at all when you get infected.
Even windows 10 windows defender puts up a better fight than those 2 antiviruses combined with malwarebytes to help it.

 

To consume up,parts which need drivers :
1)motherboard 2)gpu 3)cpu 4)sound card
All these above with a new p build
Am I right????
Should I trust cd drivers???????
Sometimes aren't drivers already pre installed
for motherboard?????

 

Yes everything is about right of what you listed, you don't need any cd-dvd drivers windows will usually pick up on it.
No drivers are not there at times lets say you need to reinstall windows 10 professional.
You do a full format, install the os which is about 40 minutes long.
Once its done you will no longer have any manufacturer drivers, same thing can be said when building your new machine.

It will start off with nothing except what windows gives it which is generic drivers.
Get into a mode of doing that if you ever have to reinstall an os or you build a new machine.
https://www.cpuid.com/softwares/hwmonitor.html and also cpu-z should be able to pick up on your hardware and give you the model number.
Run the model number on google as shown:

My mobo: GA-H81M-DS2

*1. https://www.google.com/search?q=h81...0i13i30k1j0i13i5i30k1j0i8i13i30k1.EDpokYhqHBg

*2. http://www.gigabyte.us/Motherboard/GA-H81M-DS2-rev-10#ov

*3. http://www.gigabyte.us/Motherboard/GA-H81M-DS2-rev-10#support-dl

See how quickly that took, if you have the right info you will have the drivers to download.
Just make sure the drivers work, if not uninstall them through control panel and look for updated drivers.

 

Can I find all drivers from motherboard site????
What hardware should I add in my pc which needs drivers?????

Moderator note: one question mark is sufficient.

 

Yes give me your model number from your mobo, look on the box or manual it should tell you that.

 

I dont have problem on my pc.My question was just to learn some info
What can I add than needs extra drivers?

 

No you dont need any more "extra" drivers. long as you have the right ones for your hardware and mobo.
Thats all that matters, if it aint broken, don't fix it nor reinstall it in computer terms.

If you're still unsure I could recommend you go by eithers tomshardware or techist forums.

or

Both of them would agree with what I suggested for you if not reassure you of not to do any more than needed.

 

Thank you for your support

 

No problem.
