I am using an ATI Radeon 4850 HD video card and can't play Minecraft for more than a minute without getting errors that pause the game 3 times and then crash the computer. I have uninstalled and reinstalled both the 12-8_xp32_dd_ccc and the 12-6-legacy_xp32_dd_cc_whql drivers with no help from either. The 12-8 would actually give me an error message and want to report it and the 12-6 only pause the game with no message. They both freeze my computer forcing me to restart after 3 such errors. I am running Windows XP. I am using the mods WMLL (Whats My Light Level) and Rei's Mini-map. It also does not matter if I am running ANY mods or not as this happens all the time with Minecraft and only Minecraft.

I am at my wits end here. Anyone have any suggestions?

Thanks, I tried that after my 4th attempt at it before I even posted this. That is when I stopped getting the error messages and the game just paused when an error occured.


I just uninstalled it all again and this time I removed every single scrap of AMD/ATI/Catalyst stuff I could find and cleaned the registry afterwards. I then rebooted and reinstalled the 12-6 drivers. I tried Minecraft out and got an error about 15 seconds in, another error after 45 seconds and then it all froze up after the 3rd error about 1 minute in.

I tell you, I used to love ATI! Now I just want to rip the dang card out and smash it into pieces and buy another card! I just wish I had the money to do so.... *sigh*

I tried turning down my Hardware Acceleration more under the Control Panel, Display, Settings, Advanced and then the Troubleshoot tab.

I still have a couple of errors, but they are very far apart and I have not crashed since I changed the setting.

I hope this helps someone in the future!

Believe me when I say that it is not over heating. I just replaced a burnt out fan a couple of months ago, so I do keep up on them to make sure they are working. Besides I checked the video card to see if it was hot and it wasn't. I've had this problem after just starting up my computer, so it's not heat.

I found out that it was both Rei's Mini-map and Optifine HD that was causing my problems. I was mistaken about it having problems while playing Vanilla (no mods.) I got a MagicLoader and tried all of my mods that I used individually and found it was those two mods. Rei's Mini-map caused a few little errors, but none that caused the game to freeze. Optifine after 3 errors froze the game up. I also found that the errors messed with Java. If I Ctrl-Alt-Del and stop Java, I was able to continue using the computer, but would have to restart if I wanted to play Minecraft again. If I didn't restart before playing Minecraft again, I got the Bad Video Driver error.


As for it maybe being a heating problem, it isn't. After I replaced the fan, I found that one of the capacitors in the mainboard had gone bad and a friend of mine replaced ALL the capacitors with high end capacitors. No more heating problems.

Thank you all for your help!
