Bad diagnostics.

I've been off the air, so to speak, for a few days since my computer was in the shop.  It had started making this terrible noise and I was afraid it might burst into flames or something.  The shop had it for a number of days and when the guy called he regretted to say that, although the machine had been left on, nothing happened.  I asked if they had looked INSIDE the computer.  Nope.  Geez.  Seems to me that if the noise is coming from INSIDE the computer one would look INSIDE.  Well, they looked inside and guess what?  They found some little itty bitty pieces of black plastic and a teeny, tiny brass cog-like thing.  Could that have been the cause of the noise?  Maybe....but now my CD drive doesn't work!  I'm calling them today to register my displeasure (to say the least) and let them know that I don't believe I'll be taking my computer to them anymore.  And when did I give them permission to install Malware software?  I didn't so I'll let them know I am unhappy about that, too.
It's good to be back and I've caught up reading all my favorite blogs.  Looks like I may have to invest in another computer or find someone who can fix this one without costing an arm and a leg or the price of a new one.  Oh, I forgot to mention that when I said my caps lock light didn't work I was told that it was part of the keyboard and therefore the keyboard would have to be replaced.  NOT!
Y'all have an interesting day......
