Labor costs at most computer stores are quite expensive, you are better off finding a computer savvy friend to do it for you.
A laptop if you want a complete computer that you can carry around (there is a CPU in a laptop)A CPU if you have a computer and want to upgrade or replace the "Central Processing Unit" which is the most expensive and complicated component.
Your motherboard may need to be changed when your CPU is upgraded.
Hmmm, a CPU (processor) stores no data. RAM or Memory can store data as long as the computer is ON and the Hard Drive can store data indefinately (forever).
There will be no effect on the computer speed if a CRT monitor's power cable is directly connected to the CPU. Though the PSU, or, the power supply unit must be upgraded to a 500 W one .
The CPU, obviously.
The Lenovo b575 is a ball grid array CPU and cannot be upgraded to a higher one. Only a pin grid array CPU can be upgraded to a higher processor.
A local computer store tells me they charge 30$ for a CPU install.A chain store would probably charge you a lot more.However that comes with a warranty.
bios & cpu
The function of the CPU (Central Processing Unit) is the heart of the computer. Everything the computer needs to do has to go through the CPU. The CPU tells the computer what to do, when to do it, and how to do it.
The "main brain" of a computer is usally known as the CPU or the Processor(s) but really if you think about it a brain can compute and store so really the "main brain" would be the CPU and a harddrive or other storage device
CPU stands for central processing unit. As the name implies, the CPU processes everything the computer does and handles everything that goes on in a computer. The CPU is often referred to as the brain of the computer since everything goes through the CPU first. The purpose of the CPU is to read machine language and do what it is told by it. The machine code are the directions on what the CPU should do, but the CPU is needed in order to read this code.
Intrex tells me they will install a cpu for 30$.If you go to Best Buy it's going to cost you a lot more.
