off topic but figured I would check

Check with your electric company if there's something going on around you and your neighbours are having issues as well. I recently learned that if it's a transformer issue and it's causing damages, the utility company is likely responsible and will cover repairs. Power surges are generally caused by lightening and don't just happen. I've been dealing with this on a 200,000 sqft building and HVAC equipment being fried, but have ruled out surges. You may want someone to come in and do a thermoscan of your electrical in your house if nothing is found on the main equipment.
