Around 2010, I upgraded my Integrated Graphics card (Geforce 7050) to a Gt 210 512mb graphics card. But since it ran so slowly, I overclocked it
Now, my screen won't start, showing a black screen. Is there a way to re-enable the Integrated graphics card so I can use the computer again?

Plug out your graphic card, then go and plug the monitor cable to the motherboard. It should nicely boot through your integrated graphics and use it.
Yep then once your back into windows, lower the clocks for your video card, because obviously that's the fix. If that doesn't fix it, then you have overclocked a card to the point of no return. It may have gone to far.....into mordoor
