I've just bought a MS windows XP computer with an intel pentium 4 processor off a friend who before that had it for 2 years and yesterday i set it up and everthing was fine. However, this morning i turned the computer on and it did the normal loading windows XP screen then the screen went black and the green on button on the screen turned orange for a few seconds like it was on stand by. After a few seconds it went green again and came back on and displayed the login screen with all our user accounts. I moved the mouse to click my account and it selected it and then the mouse froze and i couldn't type my password in the box as the keyboard was also frozen then after about 10 secs like this the screen just went blank but the green power button on it still stays on.
I have tried it several times and sometimes i don't even get to the login screen before the screen goes blank. However if i do manage to click on the communal user account that isn't password protected it still freezes the mouse after the one click but after the 10 seconds when the screen goes blank i hear the loading tune as if the computer has loaded the communal account.
Please can someone help me, i don't understand how it has just suddenly stopped loading after 2 years! Thanks very much.
