Hi. I moved about a month ago and it turns out that whenever there is an air conditioner or washing machine on, the lights go dim in my house and the top left of my screen starts shaking. Also, when the lights dim, my computer seems to hang for a second too. Now I don't know if I can do anything with the house (haven't asked the landlord yet) but if I can't, is there anything else that I could do?... such as buying backup power supply thingies (UPS) or an amplifier of some kind? I have no experience with any of these so any help would be appreciated. Thanks!
