Dennis,
Go into your bios and check to make sure your date and time in the bios is the same as your date and time on your windows desktop. You might have to change out your battery on the motherboard as that may be the reason the bios clock is out of sync. I just built a new PC not too long ago and started experiencing the same thing on the 737NGX. I have read on the internet that many games require the bios date and time be synced with the windows desktop date and time to run, go figure. Also make sure your bios is updated as well.
