Console gaming (XBOX, Playstation, Nintendo, etc) or PC gaming.
Leo says it's likely overheating. There could also be a memory leak of a video driver. Updating his driver will likely solve the issue. He should make sure the fans are working, too. He can also get a laptop cooler that will run fans over the bottom of his laptop. They're pretty cheap.
The chatroom also says that going into his laptop settings and limiting CPU performance to 80% and turning the frame rate down will help guard against it as well.
Matthew bought an Alienware computer and he has issues with video. Leo says that after only six months, there shouldn't be video issues. But the video card looks to be failing and Dell (which owns Alienware) should replace it. There could also be an overheating issue. Either way, Dell should fix it. Check for updated drivers as well, that would be the quick and easy fix.
Nathan is a gamer and wants to get a high end laptop. The games he likes to play are flight simulators. Leo says that a good choice may be a Windows 8 Touch laptop. The Asus Zenbook is a gorgeous Ultra Light. But Alienware makes laptops specifically for gaming. Another great gaming company is Falcon Northwest.
Don has the DOS based Duke Nukem 3D and wants to run it on his Windows 7 machine. Leo suggests downloading the free DOSbox at DOSbox.com. This is a DOS emulator that will run any DOS program right within Windows.
Leo would first check to be sure that his parents haven't downgraded to cheaper internet. If it's fast enough when connected with ethernet cable, then there's something wrong with the router. Unless he's far away from the router. One of the problems with WiFi is that less than strong signal does lower the speed.
Casey loves gaming, but consoles are slow behind the times. Leo says that console games have stagnated over the last 10 years, while PCs have leapfrogged into better graphics and faster processors.
Casey uses his PC for gaming, but he's getting a lot of lag. He's wondering if upgrading his graphics card would improve the performance. Leo says he could upgrade the graphics, but if his CPU isn't fast enough, it will still perform slow. They really work together.
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.
