I lost on avg. about 2 computers every 6 months dew to black outs and brown out's.

Basically the power spikes too high or too low and this fries circuit boards and frequency sensitive parts. This was happening with UPS battery backup's and lightning protectors.

After rewiring and doing a ton of research a electronics engineer from UK said I should get a "Automatic voltage regulator" and this will stop the slow death and loss of data/hardware even tv's / electric oven.

I then bought a several
OPTI-UPS SS1200BLK 6 Outlets Voltage Stabilizer
This cost's about $20 and since installing it I had no more hardware loss.
My power also dims the lights when the tumble dryer and other stuff goes on even after rewiring the house.

Apparently the incoming load in my area is unstable as the actual power lines is sometimes overloaded and the hillbilly town I stay in is last in line for AC 110V in the priority list. Poor town planning. Extreme town development / expansion etc.

Belkin and other Battery backup manuf. will not even pay out unless it is lightning related.

Not sure if this will help but it saves a lot of money and even my cable modem is now working normally.
