Who Do You Call?

[Morch]

We're having some reoccurring problems with both our PCs. Rattling sounds for the HD, noisy fan action, "disappearing" drives on the XP, LAN MIA as well most of the time. All of these come and go at their pleasure. Over the last few months changed MB (which did solve some of the problems for a while), last week changed the power supply thingie (ironically dubbed "the silencer") - got more noise, and the impression that the power supply wasn't all that smooth (noise level varies).

Had enough of running down to "our" shop at Panthip, only to find a bit later on that something is wrong. Don't suppose all that moving around does much good to the comps as well. As I'm not what you'd call technically inclined (yeah, I know...ought to sit down and learn some stuff), I was hoping for some advice and/or recommendations regarding computer repair services that do home visits (in Bangkok).

Thanks, and sorry if this isn't the right place for this post.
