Autocheck.exe error boot loop

So after installing bootcamp and putting windows xp pro on my macbook pro, it seemed to be workign great for awhile. Then one day after a reboot i got the autocheck.exe missing error, while booting up my windows side. Now i am stuck in a boot loop, and i do not now how to fix this problem on a mac computer. It loads to a login screen which when selecting a user "loads settings" showing a blank windows xp (no start, taskbar, or icons). then says saving settings and returns to the login screen. So i am confused and lost as where to go with this.
