I have no idea what is going on. i might not still fully understand what you are doing wrong.
i don't get the "MSN or Google thru MSN" is MSN your start homepage?
if thats the case you just need to change your start page in the settings.
the bad image on youtube could be that you are running youtube in HTML5.
try this link: YouTube
if it says at the bottom of the page "Join the HTML5 Trial" then you are not running youtube in HTML 5.
if it says anything else, then click on it.
I have no idea about the clicking noise.
you obviously have some problems. you could also try to restore windows to a time before you installed chrome.
you hit the window key (open the start menu), then type in "system restore" and hit enter.
go through the guide and choose the data before all this happend.
