So I just built a new computer and a couple of growing pains but thought I had it all figured out and now I have this new problem. This computer is only weeks old, all brand new parts.
Here are the specs:
-ASUS Sabertooth 990FX R2.0 AM3+ Motherboard
-AMD FX9370 Vishera 4.4/4.7Ghz Black Edition 16MB Cache Socket AM3+
-ASUS AMD Radeon R9280X-DC2T-3GD5-V2 R9 280X 3GB GDDR5 PCI-E3.0
-Corsair CMZ8GX3M2A1866C9 Vengeance 2x4GB DDR3-1866 CL9
-Seagate Barracuda ST1000DM003 1TB 64MB 6Gb/s SATA3
-ASUS DRW-24D3ST Green DVD Writer SATA
-ASUS PCE-N15 Wireless N300 PCI-E Adapter
-Corsair AX Series AX860i Digital 860W Modular Power Supply 80Plus Platinum
-Nanoxia Deep Silence 1 Mid Tower
-XSPC RayStorm 750 AX240 WaterCooling Kit
Now... Originally I didn't have the water cooling and I only installed this upon finding that the original cooling I had was far from adequate. (The processor is like double the wattage of normal CPUs) So if the problem is possibly an inadequate power supply due to the water cooling upgrade then this may have been the 'tipping point.'
However when I first installed the water cooling it was working fine. It was only on about the second day that it started crashing if I played BF4 on full spec for a few hours (crashing as in suddenly cutting all power, no blue screen etc). Then it did the same thing again a couple of times in the next week, both times after playing BF4 a lot, too. However these times it would crash long after I'd exited BF4. After all of these crashes I would press the power button to try to turn it back on but within a second I would hear a large 'click' from the PSU and it would turn off, only to not turn on again at all unless I flicked the I/O switch on the back of the PSU, but then again it would also make a 'click' after less than a second and turn off again. Only a long downtime allowed it to turn back on.
So a few days ago I played BF4 for a few hours. Then I stopped playing and browsed the net for a while and shut it down normally. The next day I got back from work and I encountered the same problem. Only this time the computer hadn't crashed last time I was on it, and I hadn't used it in a good 16 hours. It did this for half a week and it would click and turn off each time I tried to turn it on without fail. I thought I wasn't going to be able to get it working again.
However just now I unplugged everything from the PSU except the mobo and CPU and turned it on and it worked fine. Then I plugged in the HDD and tried again. Fine. Then I plugged the GPU in and voila, here I am again using the same computer I am/was having problems with. The only thing that isn't plugged in right now is the CD/DVD drive and I'm scared to plug that in again as maybe THAT is the problem if I've seemed to got a working computer again without it being plugged in...
I did a power supply calculator and I was pretty generous with my inputs and as far as I can tell 860W is plenty for this system. So now that I've got the computer back on again and everything seems to be in order and working just fine, I'm really confused as to what this problem could be.
Does anyone have any ideas?
I'm going to play some more BF4 tonight and see if I get the same problem again without the D: plugged in. Until then... ???????????
Make sure everything is fully seated and nothing is shorting to the case, haven't seen any issues like that lately but in the old days I had some problems with something shorting to the back of the board and it acted like that, they used to recommend paper washers on each screw where it went through the motherboard to the standoff. Make sure your memory is fully seated too but in that case you'd probably get a beep code not what you describe.
The "click" you're hearing sounds like a breaker in the power supply kicking and then your comment about it won't start again until you hit the physical power switch on the back adds credence to a bad or overloaded ps. With most items that have breaker protection hitting the power switch is how you reset the internal breakers. Is the fan running on the power supply? Could it be overheating because the fan isn't running? Did you put it on a tester to see if all your voltages are at spec? Tiger direct has a fancy tester that has a screen that actually gives you voltage readouts, not just a light. 800+ watts "should" be enough for a single video card and that power hungry cpu, if you were running crossfire I think I would have gone for something larger. I would suspect your power supply. Sometimes it's really hard to troubleshoot a bad ps too. See if you can borrow or buy another one that you can return and swap it in for a test. I am fighting with the "secondary cpu" error and it just goes black and plops and in my case it was power management, I don't think power management could have anything to do with your issue but you never know.....
