No. Unless you take out the defective stick of RAM (and still have some RAM left)
a boot program starts the operatins system stored in Ram
When you try to boot the system, you will get a POST error message and will not be able to boot.
Actually By Default this is present in BIOS(ROM) and at the boot time Operating System loads it to the RAM.
A hard boot can reset a computer's operating system and clear RAM. It should only be used if you cannot complete a manual shut down.
first the booting files are loaded in the RAM and these files are in the boot sector where operating system is installed . after loading these file then these files load the operating system in the RAM , some portion of RAM is Allocated by the OS. after that window is ready to perform tasks.
The computer most likely will not boot,RAM is how data gets from point a to point b, if theres no highway for data to travel(RAM) how can the computer boot?
The computer detects the amount of RAM accessible during boot. On some systems the amount of RAM is printed on the screen during boot.
"Quick Boot" Is a BIOS feature. During the power on self test, the BIOS checks the hardware devices and counts the system memory. Out of all of the different types of system memory, the random access memory takes the longest to be counted. Counting the RAM takes time, and on a machine that has large amounts of RAM, this calculation can take several seconds. In addition to the RAM counting, a few other tests are conducted to ensure that all of the hardware in your computer is working properly. All of these system tests are not needed every time that you boot, and can be turned off at boot time. Most system BIOS offer a feature called "quick boot." This feature will allow the user to turn off these extraneous tests. Other BIOS allow only the memory check to be turned off. Enabling the "quick boot" feature or the disabling of the memory check will not do any harm your system. The downside to disabling the tests is in the rare situation in which your RAM becomes damaged; the BIOS will not catch it and you may receive errors from the operating system and your system could become unstable. If you notice that your system becomes unstable and crashes frequently or will not even boot, go back into the BIOS and disable "quick boot" or re-enable the tests to find out if your system's memory is causing problems.
ROM
/boot directory is where all the file to boot Linux are stored it include the kernel image , initial ram disk. This files are read by the boot loader at the boot time.
An OS reside in HDD, SSD, flash drive or CD/DVD. When you boot the computer the kernel is copied to RAM. Now other parts of OS will be loaded to RAM as and when required.
The most thorough way of testing your RAM would be using a boot-up memory test (unless your computer has a built-in RAM test in its BIOS, which can be accessed by pushing F1 or F2 when the computer first turns on). Here's a link to an iso image you can burn to a CD. After burning it, you would boot the computer from the CD. If it doesn't boot from the CD, you might need to change your boot order from the bios. Set the CD drive as the primary boot location and if it still isn't booting from the CD, you may not have burned it correctly. http://www.memtest86.com/download.HTML
