Hope you guys have understood according to the title whats the problem. It is one of my friends Windows Xp home edition system that wont allow us to login, neither in normal mode nor in safe mode. I tried to search the solution on google but seems like mine is unique problem. Because the problem is not of wrong password that is not allowing me login, but actually the system login me in for few seconds when I hit enter after entering passwords and throws me out immediately in few seconds. Any solution ?
