Hello, all! First time poster here. I'm sure this topic has been covered a thousand times but darned if I can see a way to search *forums.* I can see a *blog* search function but no forum-search. I have a new computer. It's a wonderful upgrade from my old machine (the equivalent of stone knives and bearskins, to quote Mr. Spock) but I'm having one annoying issue. There are unexplainable star-shaped artifacts in my SL skies, to be exact. Wherever clouds appear, they're covered with these shapes. This effect is consistent, day and night, and changes to my graphics settings have no effect. I've read enough of the forums to wonder whether the graphics card driver installed on my machine may be the issue, but I'm not sure just what to do about that. Here are my new machine specs: ASUS Notebook G73 CPU: Intel Core Series Processor (1596 MHz) Memory: 6069 MB OS Version: Professional (Build 7600) Graphics Card Vendor: ATI Technology Inc. Graphics Card: ATI Mobility Radeon HD 5870 Windows Graphics Driver Version: 8.14.0010.0716 OpenGL Version: 3/2/9236 libcurl Version: libcurl/7/18.1 OpenSSL/0.9.8j zlib/1.2.3 J2C Decoder Version: KDU Audio Driver Version: FMOD version 3/740000 LLMozLib Version: - 2.01.31935 (Mozilla GRE version 1.8.1.21_0000000000) Assuming that it is the graphics card driver, how do I go about changing that? Assuming that it isn't, does anyone know what may be causing this issue? Stuff like this throws me since, contrary to popular belief, I'm no computer genius. Other than this issue the new machine does SL very well. Thank you in advance! Jo Ellsmere P.S. Is there a way to copy and paste text into a forum post? I tried to do that with the machine specs but apparently wasn't able to? Is there a preview function? Oh...these forums are not for the faint of heart!
