I just moved recently into an older house, I have literally [b]two [/b]grounded outlets accessible to me besides kitchen ones, only one in a bedroom... I have ran up and down checking all the breakers, removed one receptacle that was daisy chained [b]off [/b]my outlet, but I had to use the already twisted together (with a wire nut) ground from the old receptacle simply as a pigtail since the ground in that outlet wouldn't reach (idk if this is relevant, so I thought it worth mentioning), the outlet itself has no power once it was removed. A few weird things are happening... First and foremost is a random voltage flux even through my UPS (double conversion) with voltage ranging from 123 to 114 at times. Second, and this one is completely weird...sometimes when I plug my phone in with a standard USB adapter it asks to connect to my PC?!? If I use a three prong to two prong adapter between my charger(s) (yes, i've tried many, as well as phones) that never happens, as if interrupting whatever signal its getting. Considering it's on it's own 15 amp breaker (I have shut off all the rest with no issue) and powers [b]nothing[/b] else, not so much as a light switch. I'm wondering if its daisy chained in another unit above or below me. It has to be the last outlet in the chain (if one exists) as it now only has two wires connected (which i've checked, even replaced the Receptacle with a brand new one when all else failed), wire size is correct, etc. I have bought multiple tools to try and check but I'm am no electrician and I am wasting way too much funding trying to figure out this one outlet since its where my PC runs and literally the only one I care about much in the entire house. Is there a proper method from inside my unit to check if someone else is running off my outlet? I'm too green to want to touch the fuse panel. I recently bought an AC/DC Clamp Meter, Own a Multi-Meter, a Kill-O-Watts and a Socket Tester, along with non contact Voltage Testers obviously, but the Clamp Meter just confuses me and the instructions are terrible. So what would my option be? You know, besides tearing the wall down to look? We also have wired phone jacks, a wired nynex box, and a Power Inserter near my fuse panel but its such a mess I can't follow all the wires unfortunately. Any suggestions? Am I the only one who finds this to be not normal? Any thoughts would be appreciated.

I thought this would be easy and it mostly was till the end and the light did not turn on. Wires from switch black, white, ground. Wire in fixture black blue and 2 white. I matched white to white to white; and black to black to blue. What did I do wrong.
