I have had this Dell desktop into the Microcenter for repair 8 times and still is not working correctly. I have a Nividia Geforce video card. Some times the screen will go black and then a few seconds later come back on and a error message appears stating that a "Nivida video driver kernal error occured version 353.06. I tried updating the video driver and it stills occurs. Looking for a solution for this issue. The system ran great until a about three months ago.
