I have a strange problem.. when I turn ON the lights in my room my USB ports disconnect and reconnect. And sometimes when I have my Mobile Phone near the computer and it rings it will act the same. I searched everywhere for an answer.. but with no success.
I bought a UPS device.. thinking it will solve my problem.. but it didn't. I re-installed the USB drivers.. I removed the "Allow this computer to turn off this device to save power" from the USB Root Hubs. I checked my outlets with a multimeter to see if there are any fluctuations. There are non when I turn on the lights. I checked the voltages from my motherboard to see if there are any changes. Non that I could observe.
I don't know what else to do.. I'm running out of options. Please.. if someone could help me.. I would really appreciate it!!
