PC Performs Slower even with 3 GB of RAM – How to fix it?

Every personal computer has a certain amount of Random Access Memory (RAM), which is essentially the short-term memory of the computer. It is a form of high-speed temporary storage that a computer uses to store program code and open files until changes are committed to the hard drive. Addition of RAM not only increases the memory space, but also enhances the speed of the Computer. But, even having 3GB RAM the computer performance is poor. The possible cause behind the issue is described below.

PC Running Slow

Hard Drive Issue

Hard Drive issues can make the performance of the computer to slower down. All computers retrieve data from the hard drive to load programs, files and the operating system itself. A conventional hard drive stores data magnetically on rotating metal platters. Hard drives, therefore, have physical limitations that RAM does not. DDR3-SDRAM can transfer data at rates faster than 30 GB/sec, while a high-performance notebook hard drive transfers data at just over 100 MB/sec. RAM, therefore, has negligible impact on the loading speed of Windows and applications. Install a faster hard drive to increase the computer’s data transfer speed, or switch to a solid-state drive, which uses flash memory instead of magnetic platters to store data.

Latest Processor

Before installing RAM, make sure that the processor is of latest version. As features are added to new versions of software programs, the system requirements of those programs increase. For example, Windows XP Home Edition requires a 233 MHz Pentium processor, while Windows 7 requires a 1 GHz processor and performs best on processors with multiple cores. A single-core 1 GHz processor would provide excellent performance running Windows XP. However, it would barely meet the requirements for running Windows 7, and would likely perform poorly even with a large amount of RAM installed.

Update Video Card

While running applications such as games, etc. have a great effect on computer performance and has negligible effect on system RAM. The Apps like games depend highly on the performance of the computers video card rather than on RAM. If the computer performance is poorer while playing games, then an upgrade of computer’s video card will give better result in terms of speed rather than installing an additional memory.

Random Access Memory (RAM)

Lack of RAM can be one of the reasons behind the computer performance, even if the computer is installed with a high amount of memory. If there are many running applications or open files. If you use virtualisation software such as VMware, for example, a virtual machine can consume half of your computer’s memory while it runs severely limiting the number of programs that you can run on the host operating system without experiencing slowdowns.

Press the “Ctrl,” “Shift” and “Esc” keys simultaneously to open the Task Manager. Click the “Performance” tab. This window displays the amount of free physical memory remaining in the computer and upon looking to that you can find out the exact cause of you PC being acting slow. If there is a lack of memory then you need to delete some of the items from the system to fix the issue.

Windows Task Manager Performance Tab

All computers use random access memory for their memory allocation needs every moment. RAM is the place where the data are stored by the running programs.Thus, always adding an extra RAM doesn’t boost up the Computer performance. If the problem persists then you need to upgrade the RAM.
