Windows 7: Black Screen With Flashing Cursor. Cannot access safe mode.

Hello all, first time post. Earlier this week my HP desktop forced shutdown while browsing the Internet using IE9. Upon reboot the HP screen loaded, afterwards a black screen with a flashing cursor appeared. I had used CTRL+ALT+DEL function in which my computer rebooted. Showed the HP screen and immediately showed the black screen with a flashing cursor. Again no mouse cursor was available. I performed a diagnostics check in which the CPU, HDD, etc. checked out, restored BIOS to factory settings, even placing the HDD as priority 1. I inserted the Windows recovery disk and attempted a start up repair, and a restore point with no favorable results. Through the recovery disks command prompt I accessed all my music and documents, so I assume the hard drive is still functioning. I'm thinking as a last resort of performing a repartitioning of my hard drive and performing a clean install of Windows 7.

Any ideas on what I can do to solve this problem? Any help would be greatly appreciated. Thank you, Anthony.

I've had this problem before on a clients machine and the problem was with the "MBR" (master boot record)

Have a looky over here pal, maybe this might help

MBR - Restore Windows 7 Master Boot Record

Use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows

Thank you for your reply. I have preformed both tests with to no avail. Any other ideas on what it may be?
