Hassan, were you gifen a Motherboard CD (this has all the drivers required on it)?
Ethernet controller (driver)...is another name.......for the LAN card set-up.
Multimedia Audio controller (driver).........is for your onboard Audio, I persume that is what you are using.
Both of these can be found.......on that Motherboard CD.
If you do NOT have one.......visit the Manfacturer's website.........as PZ has suggested, which is the correct place to be looking.
If you use the "Add New Hardware" program.......with the motherbord CD in your CD/DVD player, follow the 'prompts' it gives......to install these drivers....from the motherboatd CD, or the FILE download.
Whenever one does a 'clean install'....of the OS, regardless of what that OS may be.........it always pays.......to LOAD ALL the drivers, once the OS has been installed.
Do NOT take this action.....for granted, as the installtion of the OS being used...............MAY or MAY NOT......set up the Motherboard.....with generic drivers!
To get your PC started, that's all.
Your challenge, therefore, reflects.....on your lack of knowledge, and the lack of proper preparation.
In order, when you do re-install any/all OSs, it is......the use of the OS Install CD, 1ST.
The Motherboard CD (the one with all the required drivers!), 2ND.
Your Interner set-up (ISP Provider), 3RD.
ALL the the Software/Programs.....you have been using regularly......this includes a decent Anti-Virus/Anti-Malware program, 4TH. (And, ALL the latest patches/updates.....to your favourite Programs! This also includes ALL the updates....for the OS!)
This is not a job...you can do, in 5 minutes.
Try more than 5 HOURS, if you are not prepared.
About 3 and a half hours..if you are.
