Hi guys I've been read threats that are simular like mine but i can't find any solution. I was playing fifa 11 when my computer reboot and when it starts again there was a display issues of the motherboard loader.Then my windows loaded normaly but aero effects does not work and when i pressed Screen resolution/Advanced settings/adapter/ All information status was unavaible.So i removed the graphics card and paste it again, i start the computer and there were not display issues over the model of the motherboard loader. I installed a new driver got from nvidia.com for 9800gt and everythig was working, I start playing some game and everything freezed including the sound. I pressed the reset button because there was nothing to do and windows loaded normaly but with the same display issues and without the aero effects. When i see the display adapter in device manager Display adapters/NVIDIA Geforce 9800Gt/Properties/Windows has stopped this device because it has reported problems. (Code 43). So I don't know what to do? I will be very gratefull if somebody know anythings about this type of problem.
