Is it normal for my kitchen lights to lower their intensity for a second when I'm starting my microwave oven? Is it a symptom of a bad/particularly unstable power environment?
The reason I am asking is because I have had episodic problems with my computer turning off at random times, and I have already checked the power/reset button connections to my motherboard, ensured that my power supply unit is running probably, and made sure that my computer is not overheating.
Should I invest in a UPS or run further tests on my apartment's electric stability?
Would an outlet tester help in any way?
