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.
The information I want you to post is the stuff that is circled in the example picture I have attached.
To make sure we are getting all the correct information it would help us if you were to attach a screenshot like the one below of your Speedfan results.
To do a screenshot please have click on your Print Screen on your keyboard.
- It is normally the key above your number pad between the F12 key and the Scroll Lock key
- Now go to Start and then to All Programs
- Scroll to Accessories and then click on Paint
- In the Empty White Area click and hold the CTRL key and then click the V
- Go to the File option at the top and click on Save as
- Save as file type JPEG and save it to your Desktop
- Attach it to your next reply

Now please what do you mean about moving it to the basement?
Is the problem only happening when you plug it in there or is it happening where you have it plugged in now?

The next step is to test the system with just the motherboard and no devices.
Disconnect everything from the Motherboard except
- video output
- 20+4 powercable
- 4/8 pin 12v wire both coming from the powersupply,
- Cpu fan wire
- power and reset button to the case
- case speaker
The goal here is just to test the mobo:
If the computer still will not boot up the please remove the motherboard from the computer along with the power supply
place the motherboard on a piece of card board larger than the motherboard,
this will eliminate a short from the mobo to the case which could be a possibility
Install the cpu with, 1 stick ram in dimm 1, power supply, case switch and case speaker
Connect ps2 mouse and keyboard along with the monitor
Repeat the above and power on
If the computer now boots into bios you most likely had a case short so make sure when installing the motherboard in the case that you use standoffs,
and they line up with the mounting holes in the motherboard and none of the standoffs touch anything else on the underside of the board.
Thanks to Cbarnard for these instructions

What I am suggesting as a more logical reason is the motherboard is failing.
From your description when you power it on NOTHING is powering on.
Now the only logical explanation is a PSU that is failing or a motherboard failing.
The PSU is showing good voltages but that could be a false positive result seeing that it is running. That would not discount the possibility the PSU may be failing.
Since the system according to you does not power on when this happens then the above mentioned possibilities are the only two reasons for this.
Heat would not be a factor as neither sensor readings showed a problem with heat. Since you shut it down and move it and then the issue starts the system would have cooled down. Additionally if heat were a problem the system would shut itself down.

The PSU (as per the reports) does not show an issue. I will say it does sound power related. It could be a marginal PSU, a problem with your house power (grounding), or the main board. I suspect a marginal component could be at fault.
I would try another PSU. It is the easiest at this time (unless proprietary like a Dell).
