I just recently installed my 280 gtx video card. Everything seemed to work out fine except when i go to reboot it pulls up verifying DMI pool stalls for 3-5 minutes the pulls up a PXE-MOF:exiting NVIDIA Boot agent. Disk Boot Failure, insert system disc and press enter. So when i put in my recovery disc everything works great but it wont boot up by itself, and i have tried getting into bios numerous to look and change what boots up first but cant get in there. Never had it booting to disc to begin with so dont really know why it would just change from putting in a new video card. Any advice much appreciated.
