I really like this site, the top pic with the servers is awesome. Get rid of the drupal drop as your icon. Other than that keep up the good work!
I would post a mini google maps on your page so that people can easily see where you are. Possibly some customer review instead of credentials. And like Brandon93 said, change the drupal icon.
I would suggest doing some keyword research on Thousand Oaks computer repair Newbury Park computer repair Westlake Village computer repair Palmdale computer repair Find out how many searches per month there are, then writing some articles targeting these keywords
computer tips section is not user friendly. these article not relevant according to the site need. try more interesting content with relevancy.
