I ask how this is going on? How to solve? (Does not seem well-being without memory problems). These two are not mutually contradictory Mody? Thank you very much! How will use a 200M memory? I am just getting on plane is such ah?Another very important point is this: the increased memory, I do not think the computer has the slightest change quickly! This is how it's going on?
Experts answer: 1: Your question is very clear to show that you state your video card is integrated. In this case part of the memory used in memory cards (usually defaults to 8M). 512-8 = 504 when you boot if BIOS hardware test shows that you may clearly see that the beginning will show in the top of the screen memory capacity (memory replacement parts), which is the adjustment in the BIOS, and methods is also very simple instructions suggest that you read the following motherboard. 2: When you have the machine shippedOK, while the physical memory will be set as the background process, that is, these programs take up your physical memory. You can see in Task Manager what procedures are taking up much memory.
