Windows 7 requires that a computer meet certain minimum requirements in order to run. To run well the specifications are even higher.

The CPU and the motherboard are two that are possible to upgrade but cost more than a used computer that meets Windows 7 specs.

SEE specs. Then download a program (FREE) called Speccy

and compare your computer against the recommend specs. Then decide if you really can upgrade.

i would go no less than 2gb ram for windows 7.

To re-start just turn it off, then on.

An old computer will not run Win7.
