Hi, So we've finally managed to get Win 7 installed on my new MSI motherboard MSI MAG B550 TOMAHAWK AM4 AMD B550 SATA 6Gb/s USB 3.0 ATX AMD Motherboard. The USB drivers were inside the install because MSI was blocking my mouse & keyboard. The computer is working, but I'm having problems with my mouse double clicking all the time, and even typing on the computer is harder then before. Someone suggesting changing the USB drivers, but we don't know how to do that. I can't insert the link in here b/c I'm a new member, but we got these drivers from a mediafire page. We don't know how to install & replace the existing drivers if someone can help please. We tried installing the .inf files by right clicking & install, but it said it can't. Thanks a ton
