Error on my ASUS Installation Disk

My Asus laptop was experiencing slow performance and so I decided to reformat it. The reformat process was successfully done but when I installed its drivers using the Asus CD Driver, my frustration had started.
I had loaded and run the Assussetup.exe but in the middle of the installation process, it was interrupted with this error prompts “Cannot Execute Kernel Mode Drive Service” and “Can’t Load ASUSWIO.DLL.”
What is the matter with the CD driver? I had already visited and consulted the ASUS service center to ask a help from them but it took time for them to respond. Therefore, I decided to post this concern in this site hoping that you can help me as soon as possible.
Thank you.
