just after cleaning its CPU fan because of its noise...when a open many sites and navigate and when i login to any site (it happenned 3 times while signing in to yahoo), a security alert says "information you exchange with this site cannot be viewed or changed by others. However, there is a problem with the site's security certificate." and it also says "the security certificate was issued by a company you have not chosen to trust...." and asks: "do you want to proceed?"....while signing in to google talk, a connection error come "Could not authenticate to server."....but as i said that this problem accurred suddenly after some hardware cleaning.....also when i turned the pc on, after cleaning the fan, some unnormal things came on but i started windows normally, and will scanning disk after restarting, scanning phase 2 cannot start and it stays 0% all the time!!!!!!

Is this on a company network? Or your personal home internet connection.

The certificate question is to do with SSL encryption keys, and nothing to do with your Fan. Its a coincidence that the two happened after one another.
When you surf to a site with https://... means that (in lay mans terms) you are creating a encrypted session with the web server, for this to happen some companies use a 3rd party Encryption Certificate service, such as verisign. The message you received is because you probably have changed some settings saying you do not wish to trust one of the certificate service providers.

As for googletalk, did you change your password, or perhaps you have entered the wrong username?

I could be wrong, and anything is possible, but I seriously doubt cleaning a fan will have an effect on your googletalk account, considering your googletalk credentials are kept on a google server nowhere near your PC. Unless of course you are actually a sysadmin for Google
