Problem after installing PCI USB 2.0 and Firewire card After I put in the new card, my computer had trouble seeing my Master Hard Drive. After I opened the case back up and took out the cord from the HD and plugged it back in it started working again but booted up Windows slowly. Windows automatically installed the drivers for the USB 2.0 and Firewire, but has since been running choppy... it took a while after start up to finish loading, music sometimes stutters, and when I'm recording (I have a USB 2.0 pre-amp for home-studio recording), it again gets choppy. What could be the problem? I'm no computer expert, but I did build my PC a year and a half ago. I'm just guessing, but maybe it's the power supply... Any suggestions??
