Hey there mc 1, this message only appears on the monitor, when it not connected to a computer, or is not receiving any signal at all from the computer it is connected to. I suggest you have a faulty video card. I recommend you remove the video card and attach your monitor to to the onboard video port. You may have to make the adjustment in the bios to enable this port. If you need assistance with that step let me know. Good Luck!

There could be any number of reasons for this to happen. However, the most likey reason - assuming that it runs for a bit, and then shuts down - is that the heatsink/fan on the CPU is not working, or not installed properly. Once the CPU heats up to a certain point, it will shut down to prevent damage. Perhaps the CPU fan as gone bad, or is completely clogged with dust.

How to restore corrupted BIOS of presario cq60 laptop


Whenever you upgrade the BIOS on your notebook, a copy of the previous version is stored in the HP TOOLS partition of your hard disk drive. Many HP notebook computers have an emergency BIOS recovery feature that allows you to recover and install the last known good version of the BIOS from the hard drive, as long as the hard drive remains functional. This emergency recovery feature is separate from the BIOS and is designed to work in the event of a catastrophic BIOS failure.To recover an earlier version of the BIOS on your notebook:
  1. Turn off the computer.
  2. Plug the notebook into power using the power adapter.
  3. Press and hold the Windows key and the B key down at the same time while the computer is off.
  4. Still pressing those keys, press and hold down the Power button on the notebook for 3 seconds and then release the Power button and the keys. The screen remains blank for about 40 seconds before anything appears on the display. You might also hear beeping sounds. Eventually, an HP BIOS Update screen displays.note.pngNOTE:If the computer fails to display an HP BIOS Update screen, press and hold the Power button for 5 seconds to turn off the computer. Wait 5 seconds and try again. If, after repeated attempts, you cannot open the HP BIOS Update screen, your computer does not support this function or it has a hardware problem that is preventing the tool from opening.Figure 1: HP BIOS Update screenc03376208.jpg
  5. When the BIOS has been recovered, a Continue Startup button displays and timer counts down. You can click Continue Startup to restart the computer or you can allow the timer to reach zero and the computer will restart automatically.Figure 2: HP BIOS Update screenc03376209.jpg
  6. After restoring the BIOS, if the computer repeatedly displays a message that the BIOS has been reset, then perform the steps in HP BIOS Application Selected is Corrupt or Missing .
  7. After restarting, Windows may display a message stating that the computer was improperly shut down or that a boot problem was detected. Read and respond to the screens to continue.

I got a code purple trying to restore my computer to its factory settings and now when my computer tries to boot up normally I can't log in using my old password or username and the only way I hav


With the code purple error on the screen, press the shift+f10 to open the cmd prompt.
Whe the cmd prompt opens, type the following command without the quotes "notepad C:\hp\bin\checkdmi\checkdmi.cmd", then after the REM lines add the following code without the quotes "goto cleanup". Save the file and exit notepad and restart your computer by typing the following command without the quotes, "shutdown -r -t 0".
This will cause the checkdmi function in an HP computer to bypass the tattoo check.
Hope this helps

Try the WD USB hard drive in another computer. If you can access your data on another computer then backup your data.
If the WD USB hard drive is faulty then -
It is not possible to recover data from faulty hard drivesby mortals such as you and I.
There are companies that can recover data from faulty and damaged hard drivesBUT they wll charge an arm and a leg for their services.

What will happen to the hard drive in power failure?


Power failure as in whole house power failure? Or the computer's power supply failure?
Whole house failure, nothing, the computer will shut off and require rebooting, at which time you may receive a message the computer was not properly shut down, just continue as normal.
Computer power supply failure, same thing, nothing, except the computer will not reboot as the power supply has failed.

Can't turn off Hard Drive


The error means that you are using a file on the external hard drive and that it can not close that file when it is use. You have to close the program that is using the file first.

Example:
Lets go on the assumption that you have your music collection on the external. If you still have your music player running when you try to disconnect, you will be greeting with the same error message.

If the external contains any files that your Operating System uses, you will get this message anytime the computer is on. An example of this can be your "Page File".

Shutting the computer down correctly is your safest bet until you find exactly what file is being used and what program is using it. During shut down, the computer closes any running programs. With no programs running, it will safely disconnect from the external HD because there will be no files in use.

If you manually disconnect it while the file is in use, you could very easily corrupt the file and make it unusable. This is comparable to an Operating System getting corrupted from a computer not being shut down correctly (pulling the power from wall without doing a shut down).

Hope this helps.
