during time my geforce GT 8800 (yes ik its very old) started to show some problems, at the beginning it started by showing green lines on the screen, but then it started going bit by bit,after that my pc started to freeze everytime i open a game, and now the whole graphics card is not working, i mean its working inside the pc the fan is spinning but when i go to device manager i see an exclamation mark next to my graphics card, ofc we all knw what does that mean.

The thing is that idk where are those lines are coming from, are they caused by the gpu, mother or cpu, etc..

im 90% sure that its caused by the gpu, but also im afraid that its from something else in the pc.

let me show you an example from what i get on my screen

What are your other specs? It sounds like you may have a very old machine. Unfortunately, your card may be dying. I had an old HP Pavilion and I had the same problems. Once the lines started showing up, 3 weeks later some smoke came from the pc and the card completely fried itself. Be careful and make sure you have a backup of your information. If your GPU is in fact about to die (Or go out in a blaze of glory), then you will want a backup of your important documents and pictures.

I'm thinking monitor, that second screenshot shows the system knows what is supposed to be on the screen.

Re-installing the Nvidia driver is a good idea. Make sure to do a clean install with the advanced options.
Try a different cable
Try a different monitor/TV

After that you can look at replacing the GPU. A replacement for an 8800GT will not be that expensive. Something like a GT740 would do. But a recent Intel CPU (6th Gen HD530) has roughly the same performance, so if the rest of the system is as old as the GPU, it might not be a bad idea to just pick up an off the shelf computer for a few hundred.

I was thinking the same thing. I was confused on how the screenshot was fine, but the picture of the monitor wasn't. It could in fact be a monitor issue, but the GPU output could be going bad. Reinstall the driver, check the cable and the monitor, and if you have the option, try a different output on the card.

Vertical lines as you are seeing on the GT8800 graphics card are a sign of partial gpu core failure.
Or can be down to bad solder joints on the gpu chip to the circuit board of the card.

Considering it`s now 2016 the card is about ten years old believe it or not.

Anyway to cure the problem, simply remove the cooling solution from the card it`s self.
Set your home oven to 230 c, wait till it reaches that tempreture.

Find a flat baking tray, and some tin foil.

Make four small even sized balls of aluminum out of the tin foil.

Place each ball in each corner of the card.
Place in the oven on the middle shelf and on the tray with the four aluminum balls suspending the underside of the card from the base of the baking tray.

Leave it in the oven for 15 minuets.

Open the door and remove the tray keeping it level as possible and place the tray on a flat surface that will not burn or be marked by the hot tray.

Leave it to cool gradually for 30 minuets DeadLyInCamo.

Once cool to the touch clean wipe off any old thermal paste off the gpu die of the card, and the underside of the cooling solution that makes contact with the gpu die.

Apply some fresh tim to the gpu die.
Then clamp the cooler back onto the card via the four screws provided that sit in a square around the cards gpu chip.

place the card back in your Pci-e card slot of the motherboard and connect the extra 12v pci-e power the card requires.

And every thin is back to normal and the card works fine again.

Total time to fix is about 1 hour to 1 and a half hours.

I've had a friend do that before but I didn't think it would actually work! He ended up making GPU-Brownies but he might have set the oven too hot and baked it for too long. Hopefully that works!

Seems like a lot of effort for an 8800GT. It may not be the problem either.

And more often than not, people screw this up and melt things into their ovens or make it unusable for cooking due to plastic and chemical contamination.

I vote toaster oven, but then only on something worth fixing. A lot less risk in spending $75 for a new GPU or buying a used GPU for half that.

GPU: Geforce GT 8800
PSU: Apple Mac Pro Power Supply 614-0409 (980W)
Hard Disk: (1)WD 500GB, (2)Hitachi 150GB, (3)Seagate 320GB
