VGA to USB driver?

Hello,
I recently bought a cheap VGA to USB adapter for my Alienware laptop, but i bought it from a cheap Chinese website to avoid paying $50 for a name-brand one. Although, when i install the driver that comes with the adapter, it causes really weird graphical-errors on my computer. Google Chrome appears as a white box, every single game i have on Steam shows a black screen, and my Nvidia card acts weird too. After uninstalling the driver, the problems still existed. i had to do a factory restore to fix this. After that, everything worked fine again. I do not want to reinstall the driver, because i dont want to risk harming my laptop again. Does anyone have a link to a driver that can act as a replacement for this? Does anyone have a kind of universal driver that should work with any VGA to USB adapter? Or should i try reinstalling the driver, to see if it was just an error that occurred during installation?
Thanks!
Also, if you need me to post my PC specs, i can do that.

 

Did you mean to buy an external USB video card? A USB port can't put out a video signal without some sort of graphics card technology. I don't think you mean that you want to plug a USB device into a VGA port, right?

You'll need drivers specific to the device. I'd be more concerned about the cheap hardware permanently damaging your motherboard or power supply.

 

No, i already bought an adapter that plugs into my laptop via USB, then at the send of a cord that plugs into the USB is a box that the VGA cable from the monitor connects into. Here is the exact Ebay page i bought it from:

That's what I was describing. I've never seen one that cheap. I would suggest buying a legitimate, name brand external graphics adapter.

 

It's an Alienware 17. I really dont want to spend full price for something like that. i just want to be able to make due with what i already have.

 

This is what you should have purchased: mini HDMI to VGA

It seems that what you have isn't working. I don't know of a way to make cheap, bad hardware fully functional. Maybe others have better suggestions. Good luck!
