ASUS Support and Download Center
Sites such as Softpedia and Cnet are great because you can find drivers to fix problems you’re experiencing with computer hardware components, and they also have a sizable collection of shareware and freeware software packages. The big problem with them is that quite often they don’t have the most up to date drivers. No matter who the maker of your hardware is, their support and download center on their local website is going to be your best resource for the most up to date drivers available.
I have attached below a number of screenshots showing the process for finding what drivers are available for three separate ASUS products - a laptop computer, a desktop computer, and a motherboard. To illustrate, for a laptop, you would go to the ASUS webpage, select Services, then support. On the support page, you would next select Downloads. You then have three options to find the product you’re looking for, automated detection, model name search, and a manual search. Model name or number search is the quickest method, but I have included screenshots that illustrate the manual method. In my screenshots, the N53SV notebook has been selected. The version of Windows 7 that you have is selected next. I chose 64-bit. Confirm this selection and you are taken to the list of available driver types, whether BIOS, Chipset, audio, video, etc. Locate the newest driver for your operating system and download it to the folder created above.
