I just realized that my PC's surge protector hasn't been grounded for over 5 years because it's plugged into a three-prong outlet using a two-prong adapter. There's a three-prong outlet on the other side of the room, but I'd need a 15-foot extension cord or surge protector to reach it. I'm wondering: 1. Do I really need to worry about grounding? I haven't had any issues in the past 5 years. 2. If grounding is necessary, how can I achieve that without changing the outlets? 3. Is a long surge protector safe to use with a two-prong outlet, or does that pose a fire risk?

You definitely need to be careful about grounding! It only takes one surge to damage your equipment. If you want grounding, look into getting a grounded outlet box and a proper adapter for it. Just remember that using underpowered wires or an extension cord could lead to fire hazards, so choose wisely!
Check the wiring behind the two-prong outlet; it might be grounded even if it doesn't look like it. Adapters can sometimes have a grounding wire that can be attached under the center screw, provided there's a ground wire in the junction box. Otherwise, replacing the outlet could be a good option.
Most people only think about grounding after something bad happens. Your best bet is to install a GFCI outlet along with a good surge protector. Since you have a grounded outlet nearby, running a cable over is basically the easiest and safest solution.
The third prong acts as a grounding mechanism and helps protect your gear from surges. Ideally, get an electrician to install a proper three-prong outlet; it's usually cheaper than buying a long extension cord. Plus, it'll ensure you're safe!
