Evil spirits plague my home

We are sure our very old house has unfriendly spirits/ghost, it has become so much worse lately. It is sucking the electrical energy out of everything. Our new oven, fridge, and laptop all died in 2 days of each other. Now my flatscreen! Weird noises and smells and doors opening and closing by themselves. I cannot stand it anymore. I am a nervous wreck and need help cleansing my life and home, though I have decided on moving soon as I cannot afford this paranormal activity financially or emotionally. I have been very unhealthy also, with kidney/gallstones and a blood disorder. I feel so drained and have no energy anymore.
How do I cleanse my home, belongings, and myself? what scents, candles, crystals and colors could help? I really am reaching out for help. All suggestions are welcome, and needed. This is an emergency.
I have tried candles for demon/spirit exorcism and carnations.
