Question about Apple MacBook Pro Laptop Computer with Intel Duo Core 15.4 Inch PC Notebook
Computer turns on but soon goes to a darker gray screen with a window that reads: "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button." This is repeated in several additional languages. Of course, restarting the computer just leads to the same screen. Sometimes I get a light blue screen with nothing on it instead of the window described above.
What you are experiencing is simply a kernel panic. (for more information read http://support.apple.com/kb/HT1392?viewlocale=en_US ) more often than not it's just a bad instruction coming from one program to your computer. if you aren't running any applications when it happens it may be related to recent hardware installations. if it's happening close to start up i'd suggest you begin by looking at what applications you have set as start up items.

POST troubleshooting steps. Question: Post troubleshooting steps.
Additional information: This document is intended to help users who are experiencing issues with the POST and may have any of the below symptoms.
Cause: This issue can be caused by any of the below situations.
Disconnect external devices Remove everything from the back of the computer except the power cable. Turn on the computer and see if it beeps normally. If the computer has never beeped keep the monitor or display connected to see if any change occurs.
Identify beep code If you are receiving a sequence of beeps see our beep code page for a listing of different beep codes and their explanation and/or your motherboard or computer documentation. These beep codes are meant as a method of quickly identifying what computer component is failing or bad.
Check all fans Make sure all fans are running in the computer. If a fan has failed (especially the heat sink fan for the CPU) your computer could be overheating and/or detecting the fan failure causing the computer not to boot.
Check all cables Verify that all the cables are properly connected at that there are no loose cables by firmly pressing in each cable.
Disconnect all drives If you were unable to determine by the beep code what is failing or do not have a beep code disconnect the IDE, SATA, SCSI, or other data cables from the CD-ROM, hard drive, and floppy drive from the Motherboard.
If this resolves your irregular post or you now get an error message attempt to re-connect each device one at a time to determine which device and or cable is causing the issue. In some situations it can also be simply a loose cable connection that causes the issue.
Remove the RAM If you continue to to receive the same problem with all the above hardware removed attempt to disconnect the RAM from the Motherboard and turn on the computer. If the computer has a different beep code or if your computer was not beeping and is now beeping turn off your computer and try the below suggestions. Making sure to turn off the computer each time you're adding and removing the memory and then turning the computer back on to see if the suggestion resolves the issue.
If you're able to get memory to work in one slot but not another slot. You're motherboard is defective you can either workaround the issue by running the memory in a different slot or replace the motherboard.
Power cycle the computer In some situations a computer may have power related issues often caused by either the power supply and/or the motherboard. To help determine if this is the cause of your issue try turning the computer on, off, and back on as fast as possible, making sure the computer power light goes on and off each time. In some situations you may be able to temporarily get the computer to boot.
This should only be used as a temporary workaround if you're able to get this to work. Often this is good for users who may have not done a backup and need to get the computer up one more time to copy files before starting to replace hardware.
Disconnect and reconnect the CPU For users who are more comfortable working with the inside of their computer or who have built their computer one last recommendation before assuming hardware is bad is to reseat the CPU by removing it and putting it back into the computer.
Bad motherboard, CPU, RAM, and/or power supply If after doing all of the above recommendations you continue to have the same issue unfortunately it is likely that you have bad Motherboard, CPU, and or RAM. The next step would be either to replace these components and/or have the computer serviced. If you plan on doing the repairs yourself or you are a repair shop it is suggested that you replace the Motherboard first, RAM, CPU, and then power supply in that order and/or try swappable parts from other computers.
