Errors on Minecraft

[Clanky_Minecraft]

Hey there! If anyone knows, there's something going on with my laptop, each time I load Minecraft on it, it works fine, but when I open another program, it just... kicks me out of Minecraft, and shows me a Fatal Java Exception Error, and just brings me to the CW. I think it's a Java or RAM error, but I'm not sure. Any help please? (Also I'm testing out a new signature, with your reply, can you please tell me if it works? Thanks!)
