My mum has an old pc. 128 ram and 10gib hd. She went on holiday for 3 weeks and switched it off at the socket, when she got home, taking into consideration that the clocks had changed, she got a message, checksum error, click needs setting in BIOS f1 to resume del to setup. She pressed F1 to resume and it got as far as the windows loading blue screen, made a click noise and rebooted with the same option. If she pressed del to enter setup the screen went black and it just hung with a flashing curser. This computer has two hard drives, don't know whether that makes any difference. Has anyone any ideas please. By the way she is not connected to the internet, only uses it to mess around with photos and uses word.
