Check if system is booting in bios. Disconnect external peripherials except keyboard and mouse.Restart the system in safe mode,Do msconfig,disable startup and non microsoft services.If issue persist ran a diagnostics on memory and harddrive. Try to start system using 1 memory module at a time if you have 2 memory modules.reseat memory module and check.

SOURCE: my laptop is on safe
Let's diagnose your laptop together tiffanythao, and see if FixYa can help cheer you up.
Let's start by shining a flashlight at the LCD screen of the laptop, laptop on.
Shine the flashlight at various angles.
Do you see Faint images?
Another test if you have a VGA monitor available.
(CRT. Looks like a small TV. You can also use a flat LCD screen monitor, if it has a VGA cable on it.
More information on what a VGA cable looks like, and the VGA connector on the back of your laptop,
Laptop off, plug the VGA cable from the VGA monitor into the VGA connector on the back of the laptop.
Turn the monitor on, wait until it 'lights up'.
Now turn the monitor on.
If the monitor does not show any graphics on it;
Press, and hold down on the Fn key, then tap the F4 key.
This F4 key is a toggle over to an external monitor Hotkey.
Hold the Fn key down again, and tap on the F4 key.
The monitor used may be the internal monitor still, and not the external monitor. (VGA monitor)
Still no? (No faint images with using a flashlight, and/or no graphics on an external monitor)
Then I bring you to a sad diagnoses.
The HP Pavilion dv2000, Pavilion dv6000, and Pavilion dv9000 series of Notebook PC's share a common problem.
Graphics chipset overheating.
A) Chip and Chipset are slang terms to denote I.C.
B) A graphics chipset is a GPU soldered to a circuit board.
Graphics Processing Unit.
1) A GPU can be soldered directly to the motherboard (A circuit board), which is Integrated Graphics.
(Another term for Integrated Graphics is OnBoard Graphics.
Soldered directly to the motherboard. ON the motherBOARD)
2) A GPU can be soldered to a removable adapter card.
Graphics adapter card, or for short, graphics card.
The GPU in the Pavilion dv9000 series of Notebook PC's, is soldered TO the motherboard.
The method of mounting is a BGA surface mount.
Ball Grid Array,
To explain this type of mounting I'm going to use one of the older Intel Pentium 4 processors.
The one's that used a Socket 478 processor socket.
The bottom of the processor has 478 pins sticking down, from it's flat circuit board.
These pins lined up with 478 socket holes, in the Socket 479 processor socket.
Using a BGA surface mount there are no pins, and no socket holes.
The bottom of the GPU's circuit board has Solder Balls which take the place of the pins.
(Not 478 of them. I don't know how many)
The motherboard has matching Copper Pads.
The graphics chipset is set down on the copper pads, so that the solder balls are aligned with them.
Heat at a specified temperature, and length of time, is applied.
The solder balls melt soldering the graphics chipset to the copper pads.
In essence soldering the graphics chipset to the motherboard.
The Pavilion dv2000, dv6000, and dv9000 series of Notebook PC's have a poor cooling system.
Specifically the part of the system that cools the graphics chipset.
The graphics chipset overheats, and the solder connections start to melt, and this develops a bad contact.
Same cooling system as your Pavilion dv9000z,
Scroll down to about three-quarters of the page until you come to Step 25, and Step 26.
That is the cooling system for your laptop.
The flattened curved copper tube is the Cooling Tube.
The aluminum looking X shape at the far left attaches to the cooling tube.
It sits on the top of the Processor's case, and absorbs heat from the Processor.
The heat is then transferred radiantly to the Cooling Tube, and towards the black Fan Assembly.
The next aluminum looking shape to the right, (square shaped tab that comes off of the side), sits on the graphics chipset.
The Cooling Tube goes on to connect to the finned black object on top of the black Fan Assembly.
The finned black object is a Heatsink.
The Heatsink absorbs the heat from the Cooling Tube. The thin, long fins of the Heatsink radiate the heat away.
Air from the Fan helps to carry heat away from the Heatsink.
The aluminum looking square tab is a heatsink also. It collects heat from the graphics chipset, and transfers it to the Cooling Tube.
This heatsink is TOO small.
More on what I have just described in a video.
(The gentleman is selling a repair also. I am only listing the video so you can see more in-depth of what I am 'talking' about, not advertising),

test all leads that attach to your hard drive including electrical extensions SATA the leads from your (motherboard to your hard drive) make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty even something as small as faulty fan lead can cause you problems computers need all of the data and power to travel through every working device and to have an end for a computer to be able work properly a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive check all electrical extensions make sure they are securely seated even the cd/dvd drives need to have current go through make sure these devices are working check the CPU central processing unit make sure it has thermal paste and dust free secure seating also check your computer ram modules and cmos battery make sure it has charge and they are dust free and securely seated some motherboards cmos batteries are soldered in
hope it helps
test all leads that attach to your hard drive including electrical extensions SATA
the leads from your (motherboard to your hard drive) make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty
even something as small as faulty fan lead can cause you problems computers need all of the data and power to travel through every working device and to have an end for a computer to be able work properly
a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive check all electrical extensions make sure they are securely seated even the cd/dvd drives need to have current go through make sure these devices are working
check the CPU central processing unit make sure it has thermal paste and dust free secure seating
also check your computer ram modules and cmos battery make sure it has charge and they are dust free and securely seated some motherboards cmos batteries are soldered in

Restart your computer
During the boot process you will see on the screen to press a certain key to enter setup usually the Delete or F2 key
this will vary depending on your computer and operating system
Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart
hope this helps
