phoenixrising2015Hi Sorry for taking so long to get back to this project, In answer to bcavaugh post, yes I did replace the Thermal Paste when I resealed the CPU heat sink. I also just purchased a new 700 watt Power supply with new cables and all. Still the same issues, however, I believe it must be heat related because when I first start the PC in the morning it will run for about 30 seconds, then subsequent power-up will only run for about 5-10 sec until I let it sit again. I used a product called NT-H1 Noctua thermal paste for the CPU to the heat sink seal. Is that a known good product for thermal paste? Is there any way to monitor the CPU temperature or dose it log it somewhere? Any ideas on what to next would be helpful,Thanks
phoenixrising2015Well, sometimes the problem is right in front of your eyes. Upon inspecting the Mother Board I noticed that one of the CPU Heat Sink posts was not properly seated in the Mother Board. I removed the heat sink, reapplied the thermal paste and properly seated the heat sink -- System now starts and runs great !!! Thanks for all the help and ideas, this forum is very helpful.
