OK, so Im running x86 but what difference does x64 do for me & how do I change. Did I say Im inexperienced with PCs????? X86 = 32 Bit X64 = 64 Bit That's why you may see some files that say something in the title like x86_32, you know that file is for a 32 bit operating system. The reason he brought up a 64 bit operating sytem is because I think with a 32 bit you can only access a total of... 3GB of RAM? To utilize the full four, and to better utilize multi-core processors, 64 is the way to go. However.... not all programs are written for 64 bit operating systems. It's getting better though. As for upgrading from 32 to 64...... I always have trouble with that topic, upgrading the OS in general actually. So I'm not going to comment on that area since I know very little about it, just enough to squeeze by the certification exam =D I'd recommend checking out the Microsoft website. Hi, As Im SOOOOOOOOOOOOO inexperienced with PCs Ill leave things alone. Thanks for your imput Lrchr
