OK, I finally decide to lap my heatsink and apply a generic version of Artic Silver. This pretty much is a no brainer. I removed the heatsink, did some sanding, cleaned the CPU, apply the silver and reattach the heatsink. I think I spent a whopping 10 minutes doing all this and when I powered on the rig nothing happened! It just powers on and thats it, no distinct beeps, nothing! Arrgghh! I was so frustrated so I disconnected everything from the 'puter, opened up the case and checked for the obvious. I made sure nothing wiggled loose and put all back together again. Still nothing! I power it on and just get a black screen. No error beeps, nothing. Anyone have any idea?
