I have an HP Omni 100 PC. Today i turned it on, typed in my password and everything was normal. 5 or 10 seconds later it froze for a long period of time. so i decided to press and hold the off button to turn it off. then i turned it on again, and it wouldnt let me go to the password screen. all it says on the top left corner. "Disk read error occurred. Press Ctrl+Alt+Del to restart" i pressed it 3 times and all it did was restart and take me back to the "ctrl+alt+del" screen. i tried pressing f8 almost 12 times (i only press it when the PC starts) Also it didnt come with a re-installation windows disk when i bought it. im starting to lose hope on this computer...? HELP ME.
