My brother has an HP Pavilion DV7 laptop with 8GB RAM and an ATI Mobility Radeon HD 4200 series graphics card (AMD vision engine). We downloaded minecraft and played quite a bit over the summer, until a problem arose in August. He is able to play Minecraft for about 5-10 minutes with near flawless framerate (from vanilla to CrazyCraft) before the computer freezes with a black screen and a series of vertical lines (sometimes blue, other times orange, or red, or green, etc.). [It just now crashed with a brown screen...that's a new one...]
At first we though the card was overheating due to some dust buildup, so we took apart the computer and blew out the insides with compressed air (LOTS of dust in there), but he still had the crashing problem. We then looked toward software problems. We did a clean install of minecraft and Java. He is using Java 7 update 51 (64-bit), though it was still crashing with previous versions. We have updated Java and tried the 32-bit variety to no avail.
We have looked for crash reports, but conveniently enough, the system logs are actually shut down just before the crash occurs, and neither Java nor Minecraft create crash reports. We have tried to minimize the amount of other running programs, increased Java's allocated memory, and altered the graphics card settings to optimal/high performance, but nothing seems to be halting the problem.
In short, does anyone know of a way to mandate a crash report, or locate the source of the problem? Or has anyone else resolved a similar issue?
It occurs every time, no matter what. Whether he's playing a Vanilla world, to playing a modded world, to joining a LAN server on my end, to joining an online server. I am beginning to think it's not limited to minecraft, as it crashed in a similar way while attempting to play toribash last night.
Well, come to find out, it was something related to the power supply on the motherboard of the computer. Everything works perfectly fine as long as the laptop is not plugged in. That was and unexpected revelation.
