On my computer I have windows XP Professional operating system. I have a problem: my operating system doesnt turn on properly. Sometimes it reports me some errors while I booting it and sometimes offer me to load last known good configuration and stuffs like that. I cant find what the problem is.
It could be few things. Maybe you need to reinstall your operating system (you have to from time to time reinstall it, and I suppose that you know that). Maybe you have some hardware issue (could be broken RAM or your hard doesnt work properly any more). I suggest you reinstallation first and if it is dont help, then try to find some hardware problem.
