Just take your time: And make sure: 1. You pay special attention to the fitment of the cpu. Read the manual before touching it. 2. Use an anti-static wrist band, or at the very least touch the case frame for a couple of seconds before touching components. 3. Ensure the 4/8 pin CPU power connector is fitted 4. Ensure the 20/4 pin ATX connector is fitted. 5. Always mount the motherboard on stand-off's, and ensure paper or plastic washers are between the screw and the motherboard when fixing it in place. 6. Just take your time really, and remember the motherboard manual will state most things you need to know. If you really aren't sure, take a picture, upload it here and ask - it's better to feel a fool for asking than to proceed blindly and break something.
