Minecraft Forums

So, after I upgraded my PC and changed to Windows 8, Minecraft is not starting anymore. I changed my Motherboard, my processor and the memory, but the VGA stayed the same. If I'm not mistaken the video driver is the same, and the website and the windows says its already up to date.
This ANNOYING Open GL error keeps happening, here is what the program says:

This is the last driver released for the Radeon HD 4000 series. Sadly, there is no release for Windows 8.1, only 8. You may have difficulty getting it to install.

Doctor...you are saying, this is it?
I will have to downgrade my windows? No other chance?
Oh doc *sobs*, he was so young!

Also...how can I downgrade my OS? I'm exactly a PC expert...

and, thank you VERY much for identifying the problem.

No, dont downgrade to 8. You should be able still install the driver on 8.1. A quick google search brings up these instructions http://www.philoking.com/2014/03/23/fix-amd-radeon-hd-4800-driver-installer-fail-on-windows-8-1/

The previous link I posted was broken, but this is where you get the driver http://support.amd.com/en-us/download/desktop/legacy?product=legacy2&os=Windows 8 - 32

Hey man, I downloaded and installed the Catalyst Software on that page you linked, but it said it was only for 32bit OS.
Then I remenbered I already downloaded the CCC 13.1 for 64bit and after installing it (it said some erros ocorred dugint he instalation) the control panel doesn't work.
This error happens:
"catalyst control center cannot be started" "there are currently no settings that can be configured using catalyst control center"

Now, Minecraft is the only game I'm having trouble running since I changed to windows 8.1 earlier this year.

:c

What if I downgrade and the problem isn't solved? :/

Yeah, many people with the same error... perhaps the problem is windows 8.1 or the 64bit version?

Did you read this?
I went to the website and downloaded the lastest driver.
Or do you mean something else?

If so, point me the right download.

Look at this thread, since you have similar hardware http://www.minecraftforum.net/forums/support/unmodified-minecraft-client/2187327-minecraft-wont-launch-on-windows-8-1#c4
