How to fix graphics card on my pc?

I moved my hard drive from one PC to another and now it says that I don't have a Graphics card?

• I had 2 pc's one of them was very old and stuff it had a virus deleted some system32 files so i couldn't use it anymore and the other pc's motherboard was fried so it didn't work anymore. So i took the hard drive from that pc and placed it in the old pc and everything works fine except the graphics card. the old pc had some sort of Intel graphics card and the other one had Nvidia GeForce 7200. when i check my video card it doesn't say its Intel anymore. instead it says that i have Standart VGA graphics adapter and that it has no memory. i tried placing my graphics card to the old pc but i couldn't because there were nowhere where to place it. My friend says that i need intel drivers but i dont know the correct name of the intel graphics card. is there any other way to fix it?
