I have been using Google Chrome for 3 years and I got it the fastest browser ever. But I got a few problems with it from a few days. I like to browse it for my workings but I?m having many troubles with even I can?t access my own website for a few times.

I tried to update it but could not update it. They are showing the message that ?UPDATE SERVER NOT AVAILABLE?. I want to update it for faster browsing.

Is there any way to update it without losing my bookmarks? OR
Should I have to download it again for better browsing?

Your help will be appreciated.
