Hi everyone! I've been noticing a strange behaviour from my UPS when playing Call Of Duty 4. Sometimes, during playing, the UPS just starts beeping frantically. As soon as I quit to the menu, the beeping stops. This has also occurred when playing NFS Most Wanted a couple of times. However, it's most noticeable while playing COD 4. Is it some problem with UPS. It's rated at 360W (max). Thanks.
