Windows 7 64-bit My desktop keeps on "flashing" while I'm browsing the web or playing games in windowed mode. The flashing happens randomly and I can't find the cause of it. So if I'm browsing the web in firefox, for example, I would see my desktop background for a split second at random intervals. I've tried looking this problem up and all I found were people reporting that they fixed the problem by opening up the registry editor and deleting some of the registries underHKEY_USERS/.DEFAULT/Control Panel/Desktop. I, however, can't find any of the registries listed as the suspects. Any help is appreciated, thanks.
