When I install my new GeForce GTX 780, my computer wont get past acer boot screen.

CPU : AMD FX-8120
MoBo : Acer Aspire M3450(all I can get)
RAM : 16.0 Go Dual-Channel DDR3 @ 665MHz
PSU : 750W

What is the +12V rating on that "750W" PSU?

bioseb31 · Nov 29, 2013

+12V@62A
this I guess?
It's the only +12 i saw in the specs.

OK. That should be enough for the GTX 780. What card did you have in before? Did you uninstall the driver before removing it?

I had An AMD Radeon HD 7670. And I need to uninstall that?

Yes. Although I'm surprised it doesn't boot to windows anyway. But let's do that first. It's the correct way to do it...

With the old card back in, boot to windows, uninstall the driver, (it will ask to reboot), just shut down instead. Change cards and see if it will boot back to windows and load a generic driver. If so, install the new Nvidia driver. If all is well, run CCleaner to clean up junk files and registry errors: https://www.piriform.com/ccleaner

I uninstalled the driver, It didnt ask me to reboot so I manually shutted down. I changed cards but i still didnt went through acer boot screen.

It didn't ask to reboot? It had to have. Are you sure you uninstalled the right driver?

Pretty sure i did, my resolution went back to 800x600. I went in device manager, Video card, Pilot tab and then uninstall.

Hopefully you don't have a bad card. Put the old card back in, reboot and run CCleaner. (the generic driver should allow you to change rez if it bothers you) Have it do the Clean and Registry portions both. You may have to run it more than once if your system is badly messed up. When it can't find anymore registry errors to fix, you're done.

Then download and install Driver Sweeper: http://www.techspot.com/downloads/4266-driver-sweeper.html
Boot to safe mode (tap f8 at boot), run DS, and have it remove any AMD, ATI, & Nvidia GRAPHIC driver remnants it can find. Shut down and install the new card. See if you can now boot to Win7.
