Computer freezes on start up all I get is the blinking cursor on the upper left corner (looks like the DOS screen) waiting for a command to be entered. I force shutdown pressing and holding the power button wait a minute or two press power. I can hear the fans going, the disk drive moving and the hard drive light blinking then it all goes quiet except for the fans and the screen stays as previously stated. I did receive a BSOD a couple of days before and as the system was creating a dump file the computer froze so I shut down and restarted again in safe mode, run diagnostics it all came okay so I restarted normally and was able to use the computer but that was the last time. I tried to run diagnostics by pressing F9 on HP start up screen, it gives me a fail when diagnosing the memory and then freezes. I am at wits end can anybody suggest a fix to this problem? Is it a hardware or software issue? I will appreciate any and all comments, thank you in advance.

the cursor is a command prompt waiting for an instruction from the OS
it indicates that the OS is not progressing in the hard drive
take it in to a computer repair shop and have them diagnose the problem

It is possible that your computer is not able to start up (normally), e.g. problem with your Windows XP, Windows 7, etc. ... e.g. you see a blinking cursor at the top left corner of your (blank) blue screen.
If this is the case, you can try to repair your disk first ... in save mode, get to a DOS prompt, i.e. >
You may see options/commands (at the DOS > prompt) by typing HELP. One of the programs that attempts to repair the disk is CHKDSK. Type at the > prompt: CHKDSK /? to see the options
Then, run the CHKDSK command to repair the boot disk.
After completing the chkdsk, type EXIT (to go back to Windows). If necessary, shut down and power up again and see if the boot disk has been repaired.
In the worst case, you may have to restore your disk from backup, or boot from a back-up (boot disk / CD) to fix the boot disk problem. But first try to save/store all your (personal) files (while in SAFE mode) before you reformat the disk and re-install the operating system (from an installation / boot CD disk)

the operating system gone corrupt needs re-installtion

Bad hard drive?

You need to run the Check Disk Utility. You've got a missing or corrupt boot or system file.

To run the check disk utility you will need a repair disc or a operating system disc. Put the disc in the cd drive and boot from it. You want to get to the Dos Command Prompt (Black screen with white letters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice the percentages going from high to low, this is normal. Let it run to completion. Then reboot machine.

If check disk fails to solve your problem you might have to reinstall windows. Try doing a Repair Install that way you don't loose your data, documents, music, pictures, videos or programs.

In windows xp you get to the dos command prompt by selecting R for repair when the options appear.

In Vista and Windows 7 you want to get to the recovery console and look down at the bottom of the window for the Dos Command.

You don't say what Windows are you using.
Anyways, it seems like you have a corrupted BOOT problem.
On Windows Vista and Windows 7, you can insert your Windows installation CD, and choose the "Repair my pc" option.
Windows will do it automatically fro you, and you'll be up and running in a couple of minutes.
