My wife has an Acer Aspire 7645 running Win 7 Home Pro with 4 gigs of RAM. She doesn't use her computer often and she's sloppy with its maintenance and hygiene. Today she tried to open her gmail account and found that it would not load. It says "establishing secure connection" and then hangs. This shows up on all browsers. Yet, on other sites she loads quickly and without trouble. It depends on the site. For instance, when I try going to virtualdr.com I see "waiting for googletagservices.com". What? I've done a System Restore. No change. I've tried to DL CCLeaner, but browser won't take me to the download page. It just hangs. I know this is pretty broad as a descriptive process but I've never encounter this kind of behavior before. Any ideas? I unplugged and re-plugged our router too. My own desktop works just fine.

Thanks!
