I have about a 3 year old eMachine T4200 pentium 4, 2.0 ghz. It came with nvidia TnT2, I recently purchased the radeon 9200 128mb and after installing it, my computer would reboot anytime i tried playing a game or changing the settings on my display. I thought i had updated the display drivers and drivers for the motherboard/chipsets. Did i install the wrong drivers and how can i make sure not to do that again. I know i have intel 845 chipset but dont know the motherboard. the mother board uses Phoenix BIOS 4.0 release 6.0 and i have the BIOS ID 31811.em.0000.d.01122613319. What should i try? :confused: Thanks in advance
