My graphic card (nvidia geforce 9800gt) is giving me trouble. It works for awhile and then suddenly strange horizontal lines and artifacts appear and then monitor goes black, telling me that there is no video input. When i restart my comp the artifacts appear and then monitor goes black before windows loads. I can run it in safe mode but the horizontal lines are still there. I deleted all graphic card drivers and installed new ones, butt it didnt helped. I cleaned my graphic card and noticed small golden spots on it (look at the picture below), could those spots be the reason? The first picture shoves my graphic card, the second is a sample.

Replace the video card, it's going bad unless you have issues with heat in the case. It s over 80% that the card is bad though no matter what cooling you use now. Run the system with the side open and a small fan blowing on the video card. If it runs stable for a long time though games or a benchmark, then get some better cooling for you case, another fan, maybe replace the heatsink in the card.

I'd just replace the card, for $80 you can get a card a lot faster and that is not much more than what a new good heatsink will cost you to try to fix the 9800.

If the Graphics Card is displaying artefacts that's frequently a warning sign.

I don't know what temperatures the card was running at while under load, but frequently overheating is to blame for on-screen artefacts and the GPU restarting (resulting in the black screen you described).

If possible, test the card in another machine. If it still demonstrates the on-screen artefacts then you could be looking at a damaged / burnt out piece of hardware. The 9600GT is a very old card. It's also possible it's coming to the end of its life.

If it only displays the lines periodically then download some temperature monitoring software such as GPU-Z or MSI-Afterburner and watch the temperatures while the card is under load. Anything over 70°c is cause for concern, anything over 80°c is dangerous to the card.

Thanks for your answer Thelps. The problems with the graphics card appear periodically, when i turn my comp on in the morning it works fine for some time(1 hour), then the described problems appear. If i restart it when the problems appear, i can only turn it on in safe mode, but the strange lines and artifacts are still there. I turn off the comp fore longer time and then it works fine again for some time. I have a program called SpeedFan and i watched the temperatures when i successfully turned on my comp, the temperature did not get over 60, but after one hour the lines appeared and the screen went black. What about the golden spots in the picture?

Your GPU shouldn't idle at anything over 40°-50°c. You may have a cooling problem.

The spots on the card could be the result of some liquid or something in the case melting though I'm unsure, I haven't seen that phenomenon before.

Have you cleaned the card thoroughly to remove dust and particles? Try it in another machine if you get the chance to see if it duplicates the problem.

A friend removed my card yesterday and now i am using the integrated graphic card intel g33 g31 express chipset family graphics card. I haven't had problems since it been removed. My friend has a Mac so i could not test it in another comp. I had cleaned the card with a air blower there isn't any dust on it. And it was not idle, i have been on youtube and some other pages.

I agree with Hang-The-9.

It's quite possible the card is nearing the end of its lifespan. With the stock cooler installed you're lucky to get more than 4 years use out of modern Graphics Cards.

Custom coolers can give them an arguably unlimited lifespan but software progression usually makes all components obsolete unless the user just needs that machine to run a specific set of programs.

Depending on what Motherboard you're using a range of cards can be recommended.

If you're interested in saving then a whole new rig could be considered.

Your Integrated Graphics will carry you through all standard Windows applications with only Photo Editing, Movie Editing, 3D Graphics and Games Applications really requiring a dedicated Graphics Card.

Hang-the-9, Thelps. Thanks for the replies, yes probably it is time for a new graphic card. I have a Intel core 2 duo e8400 3.0ghz, what graphic card that is similar to my old one do you recommend?

Even a low end modern gaming card will be faster than the 9800GT.

Radeon R7 250X is a sweetspot in the value gaming cards and you can move it to a faster CPU at some point as well for about $100 cost. If you want something for more future use if you get a Core i5 system, 260X or R7 265 but you may need to make sure your PSU can handle those cards. The 250X should run fine on the same power supply the 9800gt is on but the 260X or 265 may need a bit more power especially if your PSU is not a very good quality one.
