evinnon Posted October 11, 2009 Share Posted October 11, 2009 My system is no longer SLI so I figured I might as well get a lower power unit and sell it to a friend who actually needed the extra power. I bought this from Canadacomputers.com 2 days ago. the problem is every time I move the mouse across the screen the HX520 emits some sort of buzzing noise. If I run ATitool the problem is even worse. The buzzing noise graduates into a constant whine. I have tried disabling C1E and EIST in the BIOS and forcing vertical sync in the Nvidia control panel but they don't solve the problem. What other solutions can I try? Thanks in advance! Link to comment Share on other sites More sharing options...
