求助，电脑蓝屏！

我的电脑是vista的系统，开网页及word时突然出现蓝屏，并有以下提示：A problem bas been detected and windows has been shut down to prevent damage to your computer.win32k.sysPAGE_FAULT_IN_NONPAGED _AREAIf this is the first time you✀ve seen this stop error screen,restar your computer.If this screen appears again,follow these steps:Check to make sure any enw hardware or software is properly installed.If this is a new installation,ask your hardware or software manufacturer for any windows updates you might need.If problems continue,disable or remove any newly installed hardware or software.Disable BIOS memory options such as caching or shadowing.If you need to use Safe Mode to remove or disable components,restart your computer,press F8 to select Advanced Startup Options,and then select Safe Mode.Technical information:*** STOP:0x00000050 (0x8828DAED,0x00000001,0x81160F8F,0x00000000)*** win32k.sys - Address 81160F8F base at 810A0000,DateStamp 498f9e9dCollecting data for crash dump ...Initializing disk for crash dump ...Physical memory dump complete.Contact your system admin or technical support group for further assistance.无法热启动，关机重启后进入安全模式，可正常使用，后来再进入断开网线后可以使用word，其他程序没有试，第二天开机就无法进入系统了，请教高手是什么原因，如何解决？vista也是不新装，我已经用了很长一段时间了，硬件的时间更长了，而且软件方面也没有最近刚装的，都是之前的，这个屏蓝得很是突然啊！
