It depends on the kind of computer you have. In desktop PCs, you would need to open up the protective box (while the computer was off, of course) and access the RAM straight on the motherboard. There it can just be snapped off and replaced with RAM of the same settings for that motherboard (i.e., SDR or DDR, appropriate clocking speed range for the motherboard). In laptops the concept is similar, but gaining access to the RAM is very brand-specific. Often times easy access is only available for additional RAM. I would recommend looking at the instructions that came with your laptop.
Yes, you can sometimes you it can fail and you will have to replace it.
The engine computer is the voltage regulator, and yes you can replace it.
The way you increase the size of RAM is to replace the RAM cards in your computer with some that have more space on them. There is no way to make a 1GB RAM card 2GB without replacing it.
I suspect RAM problem, replace your RAM, but see your motherboard manual too. But if you have AMI BIOS, then one short beep is RAM problem
RAM speed is how fast your computer goes. The more RAM, the faster your computer.
Yes, but you will need the proper engine computer.
The transmission is controlled by the engine computer. It can be replaced.
RAM ( random access memory)
The amount of RAM depends on the computer.
If the motherboard on your computer has some spare slots in it, you can buy RAM from most electronic hardware stores and either pay them to install it or install it yourself. If your motherboard DOESN'T have any spare slots then simply replace the current RAM with higher one. Make sure your purchase RAM compatible with your computer. Most computers today use DDR2 RAM while older computers (such as mine) use DDR RAM.
"First you much purchase additional RAM, after verifying how much RAM your Mac can handle. Next, make sure your computer is turned off, then turn it upside down and take out the screws on the bottom. Once inside, take out the previous RAM and replace with new RAM. Now you must replace the screws and you are finished."
The engine speed limiter is part of the computer programming and is not removable. You would have to replace/ reprogram the computer.
