Hello recently my PC came back from repairs and when I got my computer back home I had a look inside the computer and took out my graphics card to compare it to my brothers. However when I put it back in and turned on my computer the display was all jumbled up with the screen resolution being too big and lots of "dashes" of colour sprawled across my screen.
I tried to change the resolution and the colour-quality option to a higher level however after I selected two higher options I tried to click ok however the display stayed the same with none of the changes actually happening.
I decided to go onto the device managed and I saw that my Graphics card (Nvidia GeForce 8500 GT) had a yellow ! next to it with a "This device could not start - Code 10".
I decided to uninstall my drivers and take out my graphics card and load my computer without any graphics card inside and the computer loaded up fine, the screen was fine, the resolution was fine etc.
So I put my graphics card back in and the jumbled screen thing came on again, I put in my CD and installed the drivers etc and then restarted my PC but the problem was still there including the ! error.
I tried downloading the latest drivers from Nvidia but after I went through the procedure I got the message "This system was not modified."
Once again the PC without the graphics card is working fine.
I do not know what to do now, any help getting my graphics card to work again would be greatly appreciated.
P.S. My graphics card was working fine before I first took it out.
