Theres nothing to do but recheck I guess. Does anything pop up on the display when you turn it on?

Check the thermal shutdown temp in the BIOS. It might be set too low. Adjust it to match your processors max temp - 5 Celsius (or similar). Check the CPU fan and make sure it turns. Check the heatsink and make sure it's flat against the CPU. A CPU heats up quickly.
