I doubt if the florescent (or incandescent) lights would be a problem, but if you have a flicker from the power company, a UPS can save you from power surges that can cause reboots and shorten the life of your computer. You can get decent ones for around $50. And of course if you have a room air conditioner on the same outlet, that could cause voltage to drop temporarily which doesn't help either.

Good luck.
Is it OK to have my PC plugged into the same power strip as my fluorescent lights? I've had problems using fluorescent bulbs in my garage door opener and dining room lights with a dimmer switch. Also, what if my room air conditioner is plugged into the same wall outlet as the power strip that has the PC and the lights.
