Why won't WinZip or UnRAR open a Minecraft .jar file?

Episode 895

William from Redlands, CA

Leo thinks the Minecraft.jar is obfuscated or further encrypted, so he can't get into it. He wants to install modifiers for his Minecraft game. Chad of OMGCraft says that's not the way he'd want to go about it though. Chad says to use MCPatcher, which will patch the mods he wants into the Minecraft JAR files. This program will let him install his mods without having to do any coding by hand.

Why do I have to reseat my graphics card once a month to fix artifacting in games?

Episode 879

Christian from Norway

Leo says it's possible that the graphics card could be slowly working itself out of the slot causing him to have to reseat it, but then it would just stop working altogether. Leo thinks it's more likely overheating, but Christian doesn't believe that's the case and thinks it's the motherboard instead. Since Asus made the motherboard, Leo advises running the Asus PC Diagnostics. He also should try updating the firmware.

Why won't my old game give me the choice to select a better video card?

Episode 873

Mike from Riverside, CA

Mike has an older PC game, Motocross Madness 2. Leo says that if it worked on an older version of Windows, chances are it will work under Windows 7 too. Microsoft tries really hard to be backwards compatible with every program ever written for Windows. Games are the most challenging, however.

Mike's main problem is that the game doesn't allow him to change which video card it uses. Because the game is older, it probably won't be possible to select the newer card because it wasn't available at the time the game was written. This is a hardware restriction, not a Windows 7 issue.
