    Same problem here. My notebook is only functional long-term when I keep the GPU disabled. When I enable it, it can go about a maximum of 36 hours before it'll crash itself and I'll need to go into Safe-mode to disable the card. If I miss my chance to Safe-Mode, then the option no longer pops up and I need to do a system restore back to a point where the GPU was last disabled.

    I've done so much research by now that I don't really need to go to a repair shop to know that the cause is heat damage. Originally, HP's Bios' fan algorithm was disfunctional but I only found out of the update too late so it's likely either my motherboard, GPU, or the cables in between the two were just fried.

    Very poor manufacturing on both HP and NVidia's part. Their machines should be built as maticulously as passenger vehicles are built to ensure lives are not lost- because it seems after about a year, give or take, everybody who buys an HP notebook eventually finds their computer falling apart. It's a shame.

    I've finally purchased a new notebook- A DV-7 from Hewlett-Packard, and will be treating this new machine of mine like a piece of medical equipment; because if anything does go wrong and it's younger than two years old, there'll be no doubt about it that it's HP's fault and not mine.
    And, accordingly, if anything does go wrong with this second HP notebook of mine, they'll find themselves dismayed to know I'll be no longer doing business with them, nor any other mainstream computer marketer. Albeit pricey, Alienware'll be my third destination. I'm sure, as a smaller company, they have enough time and consideration to actually care about their customers welfare; post-purchase and in the long-run; UNLIKE Hewlett-Packard has led me to believe.

I am posting this just to let people know how pathetic HP is

I am having a similar problem with my DV9740us Laptop. As Felorah said, I had to go to safe mode and put the driver to an old version coz as soon as the new drivers are installed the monitor goes for a black screen. Even with that and screen flickering it worked till yesterday. Now I’m left only with one option; to go for a new laptop. I spent about 1400 $ for this so called top of the line entertainment notebook not to pay another 900$ to replace the mother board (yea it costs over 900$ to replace the mother board where I live- Sri Lanka).
To be honest, I can’t afford another laptop within this year and I had to work overtime just to buy this one. FOR SURE my next laptop is not going to be HP and as a consultant I would never recommend HP to my clients or to anyone I know to that matter coz they just rip people off

HP will not cover the repair if guaranty is expired.

Video card on your laptop is integrated on motherboard, and the repairman must replace the whole motherboard to fix it.

I quote : "Only half the screen works the rest is justa grey colouring." that is more likely a problem with the ribbon cable, connecting LCD, or with LCD screen itself, in some case , as said by the repairman , it can be the video card.
if the repairman did not open and inspected the laptop LCD display , connector and cables, then the problem it is probably the ribbon cable or the LCD panel.
The technician mentioned the motherboard, because that is the most expensive repair service, so that he can cover his back.

Ask a quote to a different technician, see if this can give you different quotes for all possible faults.

The possibilities are:

1 Replace ribbon cable

2 Replace LCD display

3 Replace motherboard.

Yes, it's true: the GPU , that in your pc is part of the motherboard, has died. But before replacing the entire motherboard try to install an separate video card - the rest of the motherboard might be working. If they have tried that and it failed then yes the only thing left is to replace the motherboard

The HP Pavilion DV's have a common problem with their motherboard which relates mainly to the overheating of the video processor to a degree that its connections (solder points) with the motherboard melts by usage, causing loose connection & hence failure of the motherboard. This is a common problem well-known by laptop repair technicians for this family of HP Pavilions.

The DV6000 and the DV9000 have a bad history of failure at the video card. Most of the failures are caused by an overheating issue. The most recent BIOS updates being released by HP have resolved many problems by making the fan run faster and more efficiently to reduce heat. Also when you buy motherboards for these systems, retailers are including small copper plates to put between the heatsink and processor and video chip to help reduce the heat load. Check any forum that mentions the DV6000 and the DV9000 and you will nothing but complaints about the motherboard problems. Most of which were or are out of warranty and consumers told to pack sand by HP support.

HP PAVILLION DV9500 everything works except the monitor??

This question requires a techincal person to first, attach an external monitor to the laptop to see if there is video going to the external monitor? Then while the external monitor is hooked up he should run full diagnostics to see if the motherboard video adapter is fully functional? If it is? He has to open the laptop and trace to see if the plug from the motherboard to the monitor needs to be reseated. The worst case scenario is you will have to replace the motherboard.

According to geek squad- motherboard problem on hp pavillion a220

If you've been told the motherboard needs replacing it could be true, especially in older laptops. Thinks get hot, brittle, and then a circuit gets broken. I recently had new motherboards installed in two Dell Inspiron 8200 computers. I found the boards on ebay for $70 ea. and had a local shop install them for another $70 ea.

Keep in mind Ram and video cards are common failures too.

There are quite a few diagnostic utilites out there to check for yourself before replacing the motherboards. If you want to spend the time look for ones from your computers manufacturer.
Let me know if this helps you

One long beep, two short beeps

You are correct, this does refer to a video problem. The video card controller is part of the motherboard and cannot be repaired.
There is a slight chance that the RAM is faulty or not making proper electrical connection and this is causing the video to fail because it uses part of the RAM (memory) for video memory.
Reseat the RAM (remove and reinsert a few times) then reboot your laptop.
Best of luck.
