I just recently replaced my heatsink on my computer from the stock Intel one to a new Zalmann (CNPS9500 AT RTL) one. I am running a C2D E6600, no overclock. I changed heatsinks because the stock one was not giving me the desired temperatures. All I did was pop off the old one, clean the processor's heat dissipator with a lint free cloth and high purity rubbing alcohol, take out the video card so I could unscrew the motherboard from the risers, put the back plate on the motherboard, put the mobo back on the risers, set the new heatsink on, and plug it in. Now I get the green status LED on the mobo to light but when i hit the power nothing happens. My only idea is that the plate on the back of the motherboard that holds the heatsink has metal touching the mobo and is shorting it. Does anyone else have ideas? I cant even turn it on to get to BIOS or anything. I changed no critical components like RAM, HDD, anything like that. Thanks for any help.

Just something quick and simple that you may have checked, you sound like the type of person who would have but have you knocked any of the wires between the MOBO and power switch? i only asked because its something ive done before and not realised for sometime lol

It's usually best to have the motherboard out of the case to mount the heatsink because of the pressure applied the engage the clips. Yes if the solder traces are touching the base it will ground out. That's the purpose of the brass stand-offs. You mentioned cleaning the heatsink but didn't mention using any thermal compound. Was that an oversight?
