A year ago, I bought a computer system with an AMD Athlon-XP 2400+\nprocessor and an MSI KT4AV mobo. Today the USB completely stopped\nworking. This system runs under both Windows 2K Pro (SP2) and Mandrake\nLinux 10.0, and USB won't work under either O/S. Moreover, every time I\nboot into Win2K, the new hardware wizard starts up, but installation of a\nsupposed new USB device fails.\n\nUnfortunately, I now know of the inferior quality of VIA chipsets.\nEarlier this year, I had problems with the on-board LAN (on both O/S's),\nso I installed a PCI LAN card. I have also had occasional problems with\nthe on-board sound (again, on both O/S's), so I plan to get a PCI sound\ncard soon.\n\nNow with this USB problem which, once again, seems to be independent of\nthe O/S, I have thought about getting a PCI USB card. But I am skeptical\nthat other VIA-based features may go screwy in time. So my questions are:\n\n1. What other VIA on-board features besides audio, LAN and USB are likely\nto have problems?\n\n2. Would it be worth it to just get a new (non-VIA) mobo instead of the 2\nPCI cards?\n\nThanks in advance for any information you could provide.
