Tried rebuilding a system I had put in the closet for a bit. However, I attempted to seat the heatsink inside the case, which may have put undue pressure on the motherboard and strained it.I've always felt I've bent the shit out of this board trying to seat the LGA775 stock intel HS. Other than this, I cannot see anything that has changed since I last put it in the closet.
It was working perfectly when I took it apart. There was an OC on it, but it had been stable for years.
Anyway. I've tried different ram(4 sticks, one must be good, and a known good PSU. I have isolated the Mobo, CPU, and Ram to a wooden countertop with antistatic bag underneath. Upon powering the system, it just jitters on and off really fast. The CPU fan moves momentarily. I have tried with Memory in and Memory Out, same result.
I don't know if this is totally safe, but I just bridge the Power_On jumper to attempt to turn the system on. Rather than trying to get the mobo close enough to a case switch,etc. I have also tried clearing CMOS with jumper as well as removing battery. I have also tried a different CMOS battery, from the board I am replacing (same model battery.)
Upon removing the 12V CPU Power connection, the computer will power on with fans and be responsive to the power button, but I fail to get any signs of post on the speaker. I don't *think* you can function without 12V CPU, and I certainly had it in before.
Thoughts? Would you bet CPU or Mobo?
I am betting it was putting undue pressure on the board trying to get that DAMN stock Intel Heatsink on. (The HS pins have to be aligned in just the right way to get tension) I've always hated the intel LGA 775 stock HS, trouble to begin with. Looks like I might just let this build go, if the mobo went. Spending money on a dead platform is so counterintuitive to me.
I can't think of anything else. I have removed the CPU from the socket and reseated it as it was before (It was working in a system just 1 month ago.)
Appreciation in advance.
