Ive been using an extension cord with a surge protector to plug my pc and monitor and other stuff, but it is comnected to a 2 prong outlet amd the extension cord was supposed to have a 3 prong but the ground prong was removed by the electrician and said it was "ok" and said that "we usually remove this, its ok" should i be worried? ive been using my pc for a year and no problems (only ram ones giving me blue / green screens)
