No I am not advertising for UPS usage <g>.\n\nI have an older AT7 mobo which has had problems in the past with my USB ports.\nIt seems they were not connecting properly in some way, since often I would boot\nand my USB mouse would not connect and occasionally I would even have problems\nwith my USB keyboard, or if I tried to move the mouse or keyboard to other USB\nports no connection was made.\n\nAbout a week ago I got a UPS for my computer and monitor. Since then all of my\nUSB ports now work flawlessly. This appears to suggest some power issue. Can\nthis be:\n\n1) Brownouts, or an unsteady electrical current, in my normal electrical\nconnections through my home's outlets ( I do live in the country ) ?\n\n2) A computer power supply ( Enermax 430 ) which is not functioning properly ?\n\n3) A short on the mobo ?\n\n4) USB ports that were not grounded properly when I originally inserted my mobo\n? ( I know there are overhanging metal tabs on the top of mobo where the USB\nports are but I never understood whether these should be touching the top of my\nUSB ports or not, or inserted between the USB ports and my back panel in some way ).\n\nAlthough the USB ports are now working properly, I am still interested in\ninvestigating any of the reasons for why they did not work before. Or maybe I\nshould just be satisfied that they now work, and leave things as they are.\n\nAny Abit hardware gurus out there with any knowledge or advice they can give me,\nI would be glad to get it as long as it is well-meant. Thanks !
