I have hp dx2355 km421av which is pretty old I can play crysis 1 in it. So I thought of putting a new gpu to replace the intergrated NVIDIA graphics . I bought a galaxy geforce 9400 gt which is low profile and does fit in the pci-e slot...

Then I shutdown my pc removed power and installed the new gpu and switched it on it opened normal with half blank screen so I clicked to install new driver update when it was installing the screen gave a video tdr failure and reboots normal with half screen any help will be appreciated..
