Don't you tell me that you are using 1 GB RAM in Windows 7 operating system. You must be having problem while working on your system, aren't you? 1 GB RAM is the minimum requirement, you must upgrade it. You may try a 4 GB RAM for excellent performance or at least a 2 GB RAM. If you are using Windows 32-bit then you can use 2 GB RAM and if you are using 64-bit Windows 7 then you can use 4 GB RAM. By upgrading RAM system works nicely, we get high performance. Hope this information will be helpful.
