we experience voltage drops and occasional cut-offs for just a
second or two with our power company, and I had the same problem as
you, until I bought a BACK-UP battery pack for my computer.
IT keeps the power going even if the electrical power goes off and
prevents voltage spikes.
It also has a warning of loss of electricity so you have adequate
time to properly shut down the computer in such occasions.
I think ----- if you talk to a knowledgble rep at the computer store
--------- he should be able to get you taken care of with such an
item.
