House wiring? (slightly off-topic)

[IXQY at aol.com]

 Hello everyone,
 I mainly lurk here and try to absorb as much info as I can. A lot of it 
tends to bounce right off though..  ; )   In the near future, I intend to 
post some questions pertaining to modifying my small but growing modular, but 
for now I have a slightly off-topic problem that hopefully someone can help 
with.

 I moved into an 18 year old house a little more than a year ago. In this 
house, I have a problem with light bulbs burning out really often. I probably 
replace anywhere from one to five light bulbs a month (!). This is throughout 
the house and is not limited to one or two light sockets. It also happens 
throughout the year, so I don't think it's related to my central AC unit, 
which I previously had thought.  Some light bulbs go out as I'm turning them 
on and others go out while they are already on.

 For the few times a month that I turn on my synths, I wonder if there is any 
electrical damage being done to them by whatever is destoying the light 
bulbs. The only explanation that I can think of is that the house wiring is 
substandard. Hopefully this is not the case, as I would think this would be 
an expensive repair bill.

 Any help or thoughts are apreciated,
 Andrew Sanchez
