motherboard won't post BIOS. building new cpu. plugged everything in, then by parts. nothing changed. went back to store, replaced the motherboard, still nothing. it came as a combo with the chip so i don't think they are incompatable. Asus M2NPV-VM NVIDIA® GeForce™ 6150 + nFroce™ 430 Socket AM2 mATX Motherboard is the board btw.
