Relation of RAM with System BOOTING (Display)

By bhavanisgreat ·
It is one of the most common problems that you start up your PC.. It powers on and you don't get a display....
As a basic step every one refit the RAM into its same or another slot by cleaning it by dust and again power on the PC and there is a display.
So my basic question is that what is the Linkage and Relation of a RAM with regards to the system to get an initial display, System Start up,
Many a times while installing Windows Xp during first 100% file copying phase it gets haulted or restarted at OEMBIOS.BIN file.. and administrator says there's a RAM Problem..
Or some times you receive a Blue Scree of Death that time also RAM is suspected for having proper working..
So how does RAM actually makes entire system and operating system work properly..
Thanking You.

To put it simply, RAM is used for all temporary data storage. From the time of the first IBM PC, problems with lost BITS in RAM have accounted for the majority of intermittent data errors. Where other parts can be the cause of a full system shut-down.

As to the POST when starting up a system. It is true that the initial startup of the system and the POST process are stored in the BIOS ROM. However, you need some RAM to run the code and send commands to the video system. No RAM or corrupt RAM, no POST and no video.

In the case of installing Windows, the test that the BIOS POST runs on the RAM is fairly rudimentary. If all of the RAM is present and not terribly mis-matched to the system, you will pass the POST and be able to start installing Windows. Windows however, places much more stringent requirements on the RAM and will crash the system if the RAM is not properly matched to the motherboard and BIOS settings.

So, you do need to match the RAM properly to the system and install it properly for the whole system to function properly.
