I think this means your motherboard is coming lose. Try hammering a few more nails through it to make sure it is secure. Of course, a dirty processor could also cause this. Have you tried pulling it out and spraying some degreaser in the socket? This usually fixes my bugs.

OP, on the off-chance that you're serious, do as following.
If you have ants in your house, make sure every kind of food is sealed away from their reach and even their ability to smell it (which is very keen). King Arthur Flour sells tightly-sealable plastic containers in assorted sizes for anything like flour, sugar, cat food; ants can't get through it. Other kinds of food, keep in sealed Zip-locs or your refrigerator or both. This, plus keeping your garbage sealed up (take the bag out to the outside garbage every night, if you have to) should keep flies out of the house too.
If you have cockroaches or (the Valar forbid) bedbugs, call an exterminator.
If you have mosquitoes outdoors, call your city government office and ask to be transferred to the office that will provide someone to help you eliminate their breeding places. (Short answer: make sure there is no stagnant water open anywhere for them to lay their eggs in.) If you've seen black widow spiders, the same. (Short answer: they like to hide in dark hidden corners and under things; clean up your yard [wear gloves] and they'll go elsewhere.)
If it's really bugging you (sorry) that the world is full of arthropods, go to your doctor and tell him/her that. S/he will refer you to a therapist who will help you learn to take your fellow denizens of the Earth in your stride.
(P.S. This should really have gone in Off-Topic, but what the heck.)
Life is not a journey to the grave with the intention of arriving safely in a well preserved body, but rather to skid in broadside, totally worn out & proclaiming "WOW, what a ride!"
