Sorry to hear about your issue but I will attempt to assist you.
It sounds like you may have a overheating issue. When you were inside checking the hd's and connections did you by chance blow the system out with a can of air?
You want to make sure the fan on the CPU and the PSU vents are cleaned out.
If you have the system running please do the following.
Download
Speedfan (The download link is to the right), and install it. Once it's installed, run the program and post here the information it shows.
