My Nvidia XFX 8600 GT 256mb is causing problems.
Yesterday, I turned my computer and my monitor said there was no DVI input signal. So i changed DVI slots on the back of my video card. No help. I checked every cable, swtiched cables and still nothing. I went to the last resort, and switched to using graphics chip integrated on my motherboard.
So today, I went to the store and they found that my video card is defective. So i exchanged it for a new one, which worked on their computers at the store.
I went home, properly placed the video card in the correct place and I got the same message saying the DVI input signal could not be found. So I decided to switch back, yet again, back to my motherboard's integrated chip, then it said you could not find the VGA input signal. Now both things don't work.
Please,a little help?
