My co-worker purchased a completely new build with near top of the line hardware. The build is so high-end because he would like to use the computer for Finite Element Analysis which requires a LOT of computing power.
2x XFX Radeon 7950
4x 8GB Corsair Dominator DDR3 1600
Intel Core i7-3930K Six-core Processor
ASUS P9X79 Deluxe LGA Motherboard
Corsair Professional Series HX850w (Silver Cert.)
The issue is this: After all hardware was installed, but no software (including windows), he would press the power-button for the first time and the computer would enter a 2-3 second boot loop. On for a few seconds, then off for a few seconds, then back on for a few seconds. He said it was not reaching POST. The CPU fan does not begin spinning either.
We diagnosed the problem and I believed it was caused by a bad motherboard because:
1) CPU fan was not turning on
2) Computer did not reach POST
Newegg sent a new Motherboard and he replaced. This time the computer worked and he was able to instal windows and start installing other applications. He then ran a benchmark program. While the benchmark program was running heavy graphics tests, the computer just shut off. After that, the computer would enter a boot-loop like before. This is currently where he is at.
A few updates though:
~He mentioned that he may have put too much CPU coolant on and it leaked off the processor (could this cause the problem?)
~He is exchanging the Radeon 7950 cards for 2 of the new gtx680 cards (personal choice from what I understand. Does he have to worry about SLI compatability with this Mother Board?)
~He has tested the PSU using the "paper clip" method, but I have doubts about its effectiveness...
Here are the major hardware components:http://www.newegg.co...N82E16820233229http://www.newegg.co...N82E16813131799http://www.newegg.co...N82E16819116492http://www.newegg.co...N82E16817139011http://www.newegg.co...N82E16814150590
What could be causing this boot-loop problem. I still believe it is the motherboard considering the problem stopped (if only for a short time) when it was replaced. Also, I noticed the Mother board has a pretty bad review with a huge mix of 5 eggs and 1 eggs. It looks like a hit-or-miss board and he is missing hard with it?
Your advice, comments, and other thoughts would be much appreciated
