I suspect that you either have a malware problem or a network config problem on your PC. There should have been no reason for an invalid hostname or an opendns.com cert to show up when you were using OpenDNS, or for the Chase site to open up using an IP address instead of a hostname when using your ISP DNS servers.
I would suggest booting from a Linux ISO (pick your own flavor), and then see what happens when you try to access the Chase site. If you still have SSL certificate and or obvious DNS problems, then I suggest connecting your PC directly to your modem (if possible) instead of going through a router, and testing again with the Linux ISO boot.
