Hello
unlike items purchased separately, graphics card, hard drive, ram memory, if you buy a computer already assembled, you only have the manufacturer's warranty
Here HP, therefore, the computer and everything that is installed has the HP warranty, if it is one year, it is one year for everything!
If you modify a component, the warranty may no longer be applicable.
