I suppose its possible I shorted something. How do I determine what it is? I think it may be the motherboard.
I do not think it is the heatsink because even if the heatsink wasn't on, the machine would still start right?
I noticed that the 2 internal fans on the Asus board do not run at all while the machine is on, but when I turn it off one starts up. very odd..and so very frustrating. I paid a lot for this machine and it looks like Im going to need to spend even more.
i've had same issue before, cleaned dust out of pc, stripped down then rebuilt only to find when i turn pc on i just had black screen no beeps nothing, i stripped motherboard back out removed cpu etc, then re-built it, reset the bios again, this time it worked, dont ask me why or what 1st problem was but it works again now, maybe my cpu was not seated correctly the first time although i cant really say.
On that ram/slot, try reseating it a couple of times.
Make sure you are gounded, Winter time = LOW relative humidity which means you can easily build up a charge. <1KV probably would never notice, but ram is 1.5V. Contrary to popular belief, you do NOT have to touch an exposed pin, just getting very close can induce a charge imbalance on an IC.
On the HSF being on correctly, you are correct, it would not have prevented initial power on as it would take a 20-> 60 sefor the CPU to reach "Shut down" temps (around 95C)
