I had a few computers die on me, they were old, but taught me a
lession. I had to tackle my voltage spikes a few ways.

1. Surge surpressor in the panel. Medium cost.
2. Ensuring proper panel grounding. Few bucks.
3. Point of use surge surpressors. low cost.

With all three, I've not had a killed another computer or electronic
applicance. So, what can you get from my experience? Tackle each
problem head on, don't be cheap and try and get a secondary benifit
from another safty device. Good luck.

#3 is not necessarily "low-cost." The el-cheapo surge protectors use MOVs to
clamp the spikes. Problem is, these MOVs, which act like fuses in reverse,
only work once (or a few times). After that, you're unprotected with no
indication of the possible peril. Better is a moderately-priced surge
protector, ~$50, that has sopisticated electronics instead of MOVs.

Look for the ones that guarantee to protect attached loads.
