Hi guys i have an intel i7 920 on an x58 with 4 gb ddr 1333 ram,a zotac gtx 480 a 21" dell monitor.A couple of months ago my ups (luminous 1 kva) would no longer give power backup if i was playing a game , while it would if i wathcing a movie or surfing the net . I have tried another ups microtek 1 kva , but the problem persists. Nowadays when my pc is connected to a 32" led tv even a small fluctuation in voltage causes the pc to restart .Plz help
