I recently switched to a new laptop running Windows 7. For some reason I am constantly getting certificate errors when hitting sites where I really shouldn't be getting them – twitter, picasa, google analytics (but gmail works), my bank, etc.
This is happening in all browsers. This is happening in all networks (at work and at home). This is definitely an issue with my laptop or operating system. I know the usual cause is my date being set incorrectly, but it's definitely correct.
The error I am getting in Chrome is the following
The site's security certificate is not trusted!
You attempted to reach www.site.com, but the server presented a certificate issued by an entity that is not trusted by your computer's operating system. This may mean that the server has generated its own security credentials, which Google Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications. You should not proceed, especially if you have never seen this warning before for this site.
I have tried manually accepting the certificate, but it doesn't work – I still get the same error every time.
I checked this answer – Endless Security Certificate Errors – and used that advice (reset my Internet settings), but it didn't make any difference.

Your problem might be that your new computer is missing some root certification authority (CA) certificates.
See this article: Windows root certificate program members
where you can manually download and install all third-party root certificates that are distributed via the Windows Root Certificate Program.
