Earlier today I tripped over a headphone cord and it flung my computer off my desk. I have an HP omni PC. It's the kind that had the computer and the monitor built together. I picked it back up off the floor. The power cord came out on impact. I set everything back up and was relived to hear it turn on. I selected start windows normally (win 7 64 bit) and it sat at starting windows forever. I eventually manually shutdown the computer. I powered back on and I got an option to start windows normally or use startup repair. I thought it would be a good idea to go into startup repair. It just sat at the light blue screen with the large white mouse sitting there. Nothing happened. Nothing appeared on screen. I turned off the computer again and am just leaving it there for now. I am worried that the hard drive may have been disconnected from the fall and that's why windows won't start. Or maybe the hard drive was damaged. Any thoughts on how to fix this? Is the hard drive the issue? I will open the computer up tomorrow to check out components but I just don't know right now. Please help. I tried doing a safe mode boot but it redirected me to startup repair. Any help I am grateful for.
