How to test computer memory to determine if it’s bad
Windows Vista, Windows 7, and Windows 10 have a Windows Memory Diagnostics Tool that can be accessed by clicking on the Start Orb and typing “memory” in the run line. Running this command opens the Memory Diagnostics Tool with two options: “Restart now and check for problems” or “Check for problems the next time while booting up computer.” Choosing either of these options runs the computer through a memory test the next time it starts up.
Memtest86 – Our recommendation for testing computer memory, Memtest86 is an x86 compatible, free memory tester.
DocMemory – Another great software solution to test the status of your computer’s memory.
PC Diagnostics – Another company that offers both hardware and software solutions for testing the majority of computer hardware in your computer, including memory.
If you have found the memory to be bad, we suggest replacing the memory with new memory.
What makes a computer fast and powerful?
Although today’s computers can execute billions of instructions every second, the processor is usually waiting for those instructions from the slower types of memory in the computer. Because RAM and the hard drive are slower than the CPU, computer processors and motherboards use cache to transfer data between the processor, memory, and components in the computer. The cache is the fastest type of memory and a computer with more L2 cache or L3 cache is capable of storing more instructions and send those instructions to the processor more efficiently.
A computer with more memory (RAM) will be capable of storing more programs that are currently running in memory. If your computer runs out of memory, the computer must swap unused data stored in memory to your hard disk drive until it is needed again. By adding this extra step and because the hard drive is the slowest type of memory your computer can become much slower if it does not have enough memory.
The bus speed of the motherboard can increase or decrease the speed at which data is being transferred between all the hardware components on the computer. For example, a Front Side Bus (FSB) of 66 MHz is going to be much slower than a 400 MHz FSB. If the computer has a slow bus, the processor has to wait longer for the instructions, which makes the computer run slower.
Crucial SSD There are several components of a hard disk drive that can make it slower or faster, which makes your computer run slower or faster overall.
An SSD drive has no movable parts, which makes it much faster than a traditional HDD.
Older computers use EIDE (ATA) cables and ports to connect the drives, which have a much slower transfer rate than the SATA cables and ports used in newer computers.
The RPM of the HDD is how fast the platters inside the hard drive spin. A 5400 RPM hard drive will be much slower than a 7200 RPM drive.
Since the cache is the fastest type of memory, a hard drive with a larger cache allows data to be handled more efficiently when it’s transferred between the computer and the hard drive.
If you play the latest computer games, a powerful video card with its own CPU (GPU) and its own memory make the game run faster. These types of video cards help with the performance of the computer by taking on the responsibilities of processing the 3D rendering and other complex tasks. The more powerful the video card is, the better it can render the 3D graphics and the faster it can handle the overall processing of graphics for the game.
The interface of a video card is also a contributing factor to the performance of the video card. For example, older AGP video cards are much slower than newer PCI Express video cards.
