Why does Google Chrome randomly close?

[screechingplot656]

Sometimes Google Chrome will just close without any notification. I have Google Chrome set to save my tabs when it closes, but when I open it back up my tabs are gone. This gets very annoying because I have to go routing through my history to find all the tabs what were closed. Is there any way to fix this? It doesn't happen often, and I can't seem to find anything that's linked to it.
I just realized that it might not just be Chrome, as I also had IE open and it closed. So it might be all browsers crashing at once for some reason. At least IE says it crashed and lets me restore my tabs.

Sometimes Google chrome system files get corrupted.
You have to uninstall it manually & again reinstall it after rebooting.

(Backup your Bookmarks before uninstalling)
After reinstalling it, it will work fine.
