Got a new processor and some games won't run

[frannypack]

I bought and installed a new processor (AMD A4-7300 APU with Radeon HD Graphics), and I've been having problems running games that used to run just fine before. I installed the drivers for the processor, but the problem remains. What can I do to fix this issue?

What exactly happens when you try to run games?

what is the make and model of the motherboard?

do you have a video card installed?
