decided to upgrade my video card and got a :
NVIDIA GeForce GT 440

also upgraded my PSU to a Corsair GS600
also added 2 fans since heating was a previous problem due to gateway not having actual case fans other then the one for the CPU.

now i get random black screens and windows give me this :

Double Check the following :-

All connections are in the right place for the PSU?

Did you fully uninstall the drivers for the old GFX card (although they maybe the same) before installing the new one?

Did you plug it into the correct PCI-E Slot?

Ill check all my connections again. The main one was the one for the motherboard which i made sure to doublecheck more then once to be seated properly.

the way i installed the new graphics card was to just shutdown pc, put new card in, power it up and then i used the disc it came with to install the new drivers. Is there a different or proper way to do it? that was the method i saw online.

And for the PCI-E slot i put it in the same slot where the old card was.

Did you uninstall the original drivers first?

Overlapping drivers can cause serious problems.

Forgot to add that this happens only when i play my PC game (WoW) if that helps any. Could the new card not be compatible with the motherboard? Where could i find this out? i tried googling it but cant find anything.

Ok so I went to device manager and uninstalled the gt440 driver but then it automatically reinstalled it without me accessing the driver files i downloaded from the nvidia site. is that normal? sorry im new to this whole messing with computers (this is actually the first one i ever bought.)

when you download the Nvidia drivers run the installer, there is an option to perform a clean/remove old drivers. Select that option. it will remove the old drivers and and then install the new drivers. Hope that that helps
