*To start off, I'm brand new to the forums - therefore I may not have put this in in the right Topic. It's under Support.*

OK, so to start off, I wanted to say that this didn't use to happen. From Nov. 2012 - Mar. 2013 I played Minecraft regularly on multiplayer AND singleplayer with very little lag and a two total crash reports. But in late March of this year, somehow, my laptop was hacked. It was DDosed, meaning that whoever it was made it so that I could not type at all or the laptop would immediately shut down. After two months of trying to fix it, I finally made a breakthrough a week ago and restored it. However, I had to reset the laptop in the process. So I re-downloaded all my old files and games and was excited to be able to fully experience the new Redstone Update. But that didn't happen.

The longest I've been able to play so far was an hour and a half on one of my own Creative worlds without it crashing. On a singleplayer Survival world the game will freeze and give me a crash report after eight minutes - sometime it lasts less than a minute. In the process of fixing the laptop, I had to use several different security systems, including Avast! and Trend Micro Titanium Security. I've now disabled them as I have no use for them at the moment, but for some reason they were blocking all Java features. I had to do a lot just to get it to download Java and use it, but the first time I tried to play Minecraft again in browser, it kept saying I was missing Java. I finally managed to turn the Java security down and use all the features, and I switched to downloaded Minecraft. Since then, it continually crashes every time I try to play, usually in about eight minutes. I decided today after researching it to download MCPatcher and use it with Optifine, and convert the texture pack I use (Ovo's Rustic Redemption) to it, but it still is crashing. I don't know what to do at this point, so I'm just going to post the Crash Report below. The reason for the crash is always the same: Updating Screen Events
