I have an Emachine. I recently bought a bunch of new hardware: motherboard: PCChips P23G v3.0 Via Socket 775 MicroATX Motherboard / Audio / AGP 8x / 10/100 Ethernet LAN / USB 2.0 / Serial ATA / RAID / CNR graphics card: ATI RADEON 9600 PRO / AGP 8x / 128 Bit / 256MB / Open GL / DVI / DirectX 9 memory: 1GB DIMM I bought all of this thinking to upgrade my computer, now I have a problem, my CPU won't fit into my motherboard. the CPU is a Celeron D mPGA478B and the motherboard is LGA775. I know this sounds pathetic, but can you give me a link to a CPU that would be compatable with the motherboard? I bought the graphics card and the memory first, and when the graphics card didn't fit into the motherboard (AGP isn''t exactly compatable with a PCI slot, I didn't know then) I bought the new motherboard, Im kinda getting scared of choosing my own because im worried i'll get another problem. Another thing, should I get a new PSU?
