I have a new Dell Inspirion One with Windows 7 & to my extreme frustration it keeps on acting up. The problem is all of a sudden the screen goes black , and stays black , but the power is still on. This happens with more & more frequency but Dell has just reset, then completely erased my computer twice & it is still doing this.I've run every scan on my computer & even on the Windows site & the computer comes out clean & it only says ''unknown event occured''.When i'm watching streaming t.v the picture will freeze first and often make a strange noise like a Emergency Broadcast sounding beep. Dell will fix the computer for free , but they are saying this is software & want me to pay 200- for software support. I know nothing about computers but they erased it twice, so how can it be Windows & how annoying, the damn computer came with Windows & they want me to pay to fix it ..... Please Help !!!!!!!
