It might be an idea to do a safe start or whatever you call it for windows. Use your disk & file utilities to check your system over. Defragment your Hard disk drive. Perhaps clean out the registry if you have a utility that can do that 'safely'. You could also try the Repair option for some of these troublesome apps. ie: Program Add/Remove control panel & select the repair option.

i dont wanna try the safe mode and all that cause i dont wanna end up messing something up and not having a computer that works
