when i start my computer now this is what comes up:

A prompt window displaying: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again.
(Then in 4 other languages below it.)

panic(cpu 0 caller 0x483cbb): "_MALLOC: kalloc returned NULL (potential leak), size 4260636295"@/SourceCache/xnu/xnu-1504.15.3/bsd/kern/kern_malloc.c:572

Some more information: i havent recently updated my software or installed anything either, i read that it is possible that programs like vuze will cause this to happen but i dont believe it is the problem because i havent used it in a while.

Also i dont havr my start up disc but i do have a windows 7 disc would i be able to just run windows now?
