Can somebody recommend a good computer support teach that will come to my office and troubleshoot my computer? I'm having issues where I can receive but not send e-mails (but yet head office is having no problems with the same e-mail server) and Office keeps crashing. And also sometimes I can't receive e-mails either. I work for a non-profit agency, so I'm looking for somebody that's good and reliable, but not too expensive. I have done a vrius scan, and found no issues, so I'm out of ideas.
