It took me 6 hours to properly lap my heatsink Thermalright 120 Extreme, and then I had to take my computer apart with the Mother Board to install the heatsink. I have a thermaltake powerpro 600Watt powersupply and a Q6600. When I put everything back together, my computer won't even respond to power... I know there are thousands of possibilities of what's wrong right now, and tried to correct them, but everything seemed fine... Anyone have any suggestions. My computer won't even budge, I have the 24 pin powersupply connector connected along with the 8pin CPU connector.
