I overclocked my graphics card and now it cannot be detected by my computer

[MrGrace]

I have a Acer Aspire V3 571-G laptop (yes i know, very old). I tried to overclock the graphics card on the laptop to get a better performance on my games. The graphics card is Nvidia Geforce GT630M. I overclocked it too far and now my computer cannot use/detect it.

How do I fix?

For example:
When I run the game I want to play, it displays an error message of an intel driver update.
The Nvidia control panel is inaccessible.

Does this mean that my Nvidia graphics card is no longer usable by my laptop?

Any help is appreciated

Try remove the laptop cell battery, then reboot the laptop to see the gpu can be detected by the computer or not.
