I just built a new system P4 prescott 3.0 ghz, 1GB Kingston pc3200 Ram, 80 gb serial ata drive with an MSI 865PE Platinum motherboard and Aspire ATXB3KLW/350W case. For some reason, my front and rear usb ports do not function in windows. The additional 2 that I have in the back occupying a slot above the agp slot has lights flashing so it is getting power. There are also 2 in the front that I am positive I have plugged in correctly into the mobo (5pin over 4pin connection). Everything is enabled in the BIOS as far as I can tell but still no luck? The USB ports located directly on my mobo work fine, any ideas? This is like the last thing I have to get working right on my new PC. Thanks!
