Hi I m not sure if I m in the right place but my HP Pavillion dv8000 will not let windows boot, I was transfering some files from my notebook to another so I did a copy and paste on msn messenger it started sending the files then all a sudden it froze and I think there was a message saying that there was not enough space to transfer or copy the files, then the screen went on like standby mode (off) and wouldnt turn back on so I pressed the power button to shut it off in order to turn it back on. now it will not even boot the windows xp system it just turns on and stays like that the screen is still off and the system would not boot. Can someone please give any idea on how to fix it or what could the problem as I am extremely desperate and I dont know what to do
