Could it be an alternator problem but my cluster lights went out and power steer

What is your question?

Power steering went out and cluster lights went out and I had the AC on and I noticed it don't do that when I turn it off? Also abs lights and airbags and traction control light and battery light stays on... at one point they turn off when I accelerate and I get power steering back on so I don't know if it has to do with something else like computer problem?
