About 3 weeks ago my PC started to have ping spikes that vary from 300-2000. My sister's PC runs perfect on the wifi and I switched our wifi adapters out as we both have the same one and that has done nothing. I've updated every driver I could think of, done a full reset/wipe of my pc, and am now starting to think it is one of my pc components causing this issue. I don't know too much about computers and would really love help. Thanks.
