This sounds like a BSOD (blue screen of death). This usually means there is a serious issue either with the hardware or with windows itself. Normally a bsod will have text, along with a line in the format:
0x00000000 _ _
If you could provide the part similar to above (where the _ _ is two letters or numbers) it would allow for better understanding of the issue.

Hi,
This might be an issue with the Hard drive or the operating system installed on the hard drive.
Try to access BIOS screen tapping on F10 on restart.
If you are able to access Bios try to run the Short smart self test on the Hard drive.
To run the test follow the steps as follows:
on the main window you will see 1 st drive 2nd drive 3rd drive 4th drive.
besides these drive letters you will find your Hard drive listed.
Highlight that and press enter.
on the next screen highlight Smart support and press enter.
on the next screen select Short smart self test and run the test.
If it gives an error code that means the hard drive has gone bad.
2)If not then come back on the main page by clicking on ESC button till you come back to the main page.then Press F5 select yes to load set up defaults and press enter.Press F10 once to save configuration changes and press enter.
It will boot to windows.
3)Still if you face the same issue then you need to perform the recovery using the recovery cds.
4)If you don't have the recovery cds then you can contact HP support and order the cds and perform the recovery.
This should resolve your issue.
Thanks.

Hello,

to get into safe mode, turn on your computer and press F8 immediately. Press the F8 constantly, till the safe mode booting option will come up.

Pressing F8, is the sure way of make your computer enter into safe mode.

Good luck.

Follow these steps:

1. Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple operating systems, you can press the F8 key when the Boot Menu appears.
2. Select an option when the Windows Advanced Options menu appears, and then press ENTER.
3. When the Boot menu appears again, and the words "Normal mode" appear in blue at the bottom, select the installation that you want to start, and then press ENTER.

that's an OS problem, or malware. If you're running Windows, try to boot into safe mode (press F8 and choose "safe mode" or F5) and see if you get your desktop back. You can go directly into recovery mode from the F8 boot mode selection menu also.

Before you format your drive try to boot to safe mode and see if you can try to uninstal the uncompatiable software.

1. Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple operating systems, you can press the F8 key when the Boot Menu appears.
2. Select an option when the Windows Advanced Options menu appears, and then press ENTER.
3. When the Boot menu appears again, and the words "Safe Mode" appear in blue at the bottom, select the installation that you want to start, and then press ENTER.

To solve this will require more information from you. The Blue screen is Windows way of telling you that it has a driver issue with a basic component, usually your video card. Did you recently make any hardware changes? If so please let me know what was changed.

When windows first boots, you can repeatedly press the F8 key until you see a menu giving you choices of windows booting. You need to select Safe Mode. Safe mode should allow you to at least boot without a blue screen. The blue screen could also be cause by a virus or other software.

Microsoft has a description of Safe mode here;
