I stupidly ran a pc health check programe last night (comodo) and was given the option to either save or delete some files. I was warned that deleting them may harm my pc. Dont' ask me why but i deleted them!!! I tried starting my pc this morning but i only get to the first stage, the dell logo, before my screen goes blank. I try hitting f8 but my pc starts bleeping and i get a message saying: Dell System Optiplex gx260 series Laptops, Desktop Computers, Monitors, Printers & PC Accessories | Dell Keyboard failure I have tried several time to get past this but haven't been able to. I have windows XP Pro and SP3. Here comes the bombshell. I have absolutely no disk to try to reload or reboot. Can anyone help please.:confused:
