I wasn't sure if this would go here or in the driver section since I think that is what the problem is but I'll just post it here. I recently got a GeForce GTX 260 OC along with a VGA Booster with VGA Booster 400W to power it. I uninstalled the Intel Integrated Graphics and disabled something called a VGA Graphics Adapter. I installed the latest Nvidia Drivers, but my system keeps crashing when I am running with the 260. I don't think it is a power problem because I could be playing Fallout 3 with settings maxed, no lag, no problems for 3 minutes and it will crash, or I could be just using Firefox and it cuts out after 1 minute. The VGA Booster is designed to like an additional power supply. It takes up a DVD Rom expansion, connects to the motherboard and Main Power Supply, but also uses its own Outlet to power. The temperature can't be a problem because SpeedFan says I never go above 60C (45-50C in Idle) and everything is cold after the crash happens. The screen goes different colours when it does happen and then everything stops responding(I have tried activating Caps Lock on the keyboard and the light doesn't turn on). I could be in the middle of listening to somebody talk in Fallout3, the screen goes 1 colour, but I can still hear the person talking, or I hear the ambient sounds of the Tech Vault. I still haven't gotten out, how sad is that. The only way I can restart my computer is by pressing the power button. I think I have disabled the graphics in the BIOS as well, it only gives me a choice between PCI or PCIEx first, it is set to PCIEx. This doesn't happen when I connect my monitor to the integrated graphics, which I thought I disabled, as well as tried to un-install. I have looked around and there seems to be a lot of people that have trouble disabling the integrated graphics on a dell. I have tried re-installing the Nvidia drivers a number of times now. The only way I was able to type this long post was by connecting to the integrated graphics by the way... Any help is appreciated.
