We don't seem to have a peripheral category, so here I am! I've built a desktop with an Asus P8Z77-M Pro mother board, a Core i5 3570K CPU and a SSD. I use an Asus VE 228h LED monitor. After a week or so with the dongle in any given port, the cursor becomes erratic and eventually it will actually freeze. Sometimes a change of ports rectifies it, other times only a reboot. Definitely not the batteries or drivers. Well I guess you can't always say definitely not the drivers. Any theories? Thank you!
