Surge protector not grounded?
 

Because I moved the computer from the den into a bedroom, but the surge protector says that the outlet I plugged it in isn't grounded. All the non-bedroom outlets are grounded, but the ones in the bedrooms aren't. Will this affect the surge protector's performance, or will I not even be protected at all? What can I do about it, short of moving it back to the rooms that have grounded outlets. I don't understand why these outlets with the three prongs wouldn't already be grounded.

If your surge protector says so, just call the power company and see what they say. Surge protectors should provide some protection reguardless. But if you really want to be sure, just make sure the power company says it's okay. Honestly, I never had this problem with three-pronged outlets.
You could always buy a line conditioner to make sure the power output is always constant if you're unsure.

There are some two prong outlets that do have grounding (you can tell by the different sized plugs), but given what a surge protector is suppose to do, plugging it into a 3 prong outlet will have an affect on how well it would work.

And also it would affect how well it will stay in the wall too. 3-to-2 prong converters suck for staying plugged in properly.
