130V is within the guaranteed voltage Edison supplies us here in SoCal (+/- 10% of 120V which is 132V). If it goes above that threshold Edison is required to do something, otherwise you probably wont get any help from your provider. They don't want to adjust it since it effects others on the same transformer.
You probably can get a buck-boost transformer, though I've never installed one for that purpose.
I doubt that the voltage is the sole source of the problem. All computers should handle the voltage range that the power companies are required to deliver.
I would continue to search, I'll bet you your problem has a different answer
Good luck with it.
