Check it out, I have an AMD 6000 X2 dual core processor in an ECS Nforce 4ma mobo, put in a new Athlon II X4 630 and pc wont post. Tried to download a bios update but everytime I tried to install it, computer says it has onboard bios. Everytime I put the AMD dual core back in the pc, it boots right up. Put the new processor back in it wont post. I put in a new PSU Ultra LSP 550, its has Win 7 64 bit, 8 gigs and a EVGA 240 GT. BTW the mobo is AM2 and the new CPU is AM3. Please dont tell me Im gonna have to wait unrill I get a new mobo, cant get one right now. Any Ideas, Help.
