I've done several checks against WWV and the PC's clock is now spot on. Yes, I was having driver problems. I explained that. But I'm no longer attempting to use those and have what I believe is a stable driver for my PCI serial ports I just acquired. I'll continue checks against WWV, but as long as it check ok, I'm not going to fix what is now working ok.

Hi Larry,
Ok, I understand the need for an accurate clock, though I believe you're expectations for being able to track an overhead pass is pushing the limits of orbital prediction pretty hard. Another ham I know locally tried this, and ultimately gave up. His issue was not one of clock accuracy, but of Keps and the mathematics behind them.
But, you've still got a PC that isn't working right, and that bugs me. I just checked my PC, and it was spot on with WWV (clock changed at the chime). So, a question... Did the clock drift before the serial port was installed? Perhaps what you need is a new driver or a different type of serial port, if you haven't exhausted that route already.
