Can I install a driver for new A8-3800 AMD APU upgrade, from an A6?

I just replaced my A6-3600 APU for an A8-3800 FM1 socket. When I start the computer it says critical error, driver missing. Can a reinstall of the OS fix this? Or should I put the A6 back in and see if I can even find the drivers from AMD, I'm not sure how to go about this, or if it can even be done. There's very little info about this.
I upgraded an AMD APU on another computer I had owned about 10 years ago. It was a duel core apu upgrade and went fine, the computer just had a bit more punch to it. So I thought I'd try it with my Gateway SX2370, but maybe not.

When I press F12 for bios it takes me to a small screen with a choice of booting to the hard drive or dvd, except I lose control for the key board and mouse at that point. lol. So no safe mode.

I tried F8, and I tried the shift key with two boots, I get a solid blue screen with either one.

Nope, it just gives me a blue screen, I tried a some other F keys just to see, and nothing but a blue screen. Maybe it just won't work with the A8.

Can you get into the bios? might just need resetting for the new processor or possibly you might need a bios update.

No, it won't let me into bios. It only sends me to a small screen that gives a choice of two boot options. But after that, it kills control of the key board and mouse. Weird how the F key works, and then it goes dead after it sends me to a new screen and I can't do anything.

Well, I put the old processor back in, and she's not a happy camper now. It took 8 reboots to get the machine running, and the cpu is just cranking away relentlessly at 70% and nothings open. I just couldn't leave well enough alone.
