over roughly the past 3 months i've been receiving random reboots while i was gaming, no specific time involved.. just a reboot at a random time during gaming. I really never cared too much, but it's starting to become annoying. Anyways i have an onboard ATI video card, and i just bought an nVidia 7300 GT the other day and installed it.. ran driver cleaner and everything to get rid of the excess ATI material, hell i even downloaded the new drivers from the nVidia site. However I still get this error, now im pretty dead sure it's caused by my video card because when i checked the blue screen, the source of the error was NV4.dll(my video card driver!!)... here's the error report Error code 10000050, parameter1 e571ab40, parameter2 00000000, parameter3 bfa76d67, parameter4 00000001. could it possibly be some conflict with the onboard? please help me!!
