By now, the thermal compound has dried. The heatsink can no longer wiggle. However, I now have a much bigger problem to worry about...
I completed assembling the computer. All fans turn on, power light is on, DVD tray works, but monitor shows no signal. CPU cooler is on, but is cool to the touch... seems like CPU is not even turning on. (This is where I really wish the Antec 300 had a speaker for POST codes.)
CPU cooler is still stuck and unremovable. I think if I tried pulling the heatsink, the side latches, or the handle any harder, seems like (further) damage to the CPU or motherboard would occur.
What are my options? Should the cooler be clipped off with wire clippers?
