Got a new computer from TigerDirect.com- an Acer Aspire 5250-BZ853 with 2GB RAM stock. The website offered to add 4GB of RAM to the laptop for about 50 bucks so we went ahead and did that. However, when I got the laptop, it definitely doesn't run as fast as a laptop with 6GB Ram. I have run multiple tests and have confirmed that the RAM is installed properly, as system scans show that I have 5-6 GB of usable RAM available at any given time. Running Windows 7 with the following system specs- AMD Dual Core Processor E-350 AMD Radeon HD 6310 (graphics card?) 2 GB DDR3 Memory 320 GB HDD Is the problem with the memory? Maybe I installed the wrong type? Not sure. Any help would be greatly appreciated.
