I was ordering some pics online yesterday and the screen went black then up came a load of writing, I just had time to quickly read bits, but it said something about a disc, NTFS partition 1, very important that disc CHCD, I could stop this check by pressing any key within one second but strongly advised against it, before I could press a key it carried on checking. Should I have unplugged the PC or what? Touch wood, everything seems to be working, but does anyone know what it was please. I did a full scan with AVG straight afterwards and it said no problems, but it sounds ominous to me. It had the Windows name in the top right hand corner. TIA Shirl
