Alright, it didn't exactly crash, but here's some logs I found. There were about 18 more in the logs folder though, some were WinRAR archives and others text documents. The WinRAR ones had dates on them, so I chose the one with the date of the last time I had launched Minecraft.\
Alright, screw that. This doesn't make sense. All I did was get a new operating system and 4 more gigs of RAM. There HAS to be something that's making Minecraft freeze when I load a world. I know when I had saved a back up of my data before I switched to Windows 8 64bit. I have it on my computer currently. I'm pretty sure I had to reinstall Minecraft but I don't remember doing it normally. My friend who has MUCH more knowledge than I do when it comes to PCs had installed some sort of program that installed Steam, Skype, and all these other programs all at once. I can't remember if Minecraft was one of them. Could this possibly mean something? If not, then is there something I have to do to the Forge profile maybe? I'm not giving up yet.
EDIT: About and hour ago I tried playing the CrusaderCraft modpack on the Void's Wrath Launcher and upon creating a new world the game shut down entirely, with no warning. Could this also mean something?
EDIT 2: I'm trying to list possibilities, and another one may be hardware. My computer specs (the ones I could find) are:
Processor: AMD Phenom II X2 560 3.30 GHz
Well, that's all i could find :/ Iff any other hardware specs actually matter, tell me which ones.
Okay, so I'm thinking this may have something to do with a mod I've installed's compatibility with another mod(maybe duh). So here's a list(link, really) of the mods I've got installed (everything that resides in my mods folder).
NOTE: I am NOT using ic2, railcraft, or WorldEdit. Should I delete these folders?
