Hello! I need help from you experts!

[GOEPOA]

Good evening. I'm having trouble with my system, the PC is shutting down with no error, and no warnings.
I need an opinion for setting my BIOS configuration.
Here are the spec's of my PC.

Asus P6X58D-E
Intel i7 950 @ 3.07Ghz (Default)
Memory Corsair Dominator GT (CMT6X3M3A1866C9)
6GB (3X2GB) 1866MHZ 9-9-9-24 1.65V VER7.1A
Power Supply its a Corsair TX850W

VGA its a Geforce GTX580 by E-VGA
HD WD 7200rpm 1TB (32mb)

Info.
The specs are not new but the HD is.
I thought it was the old HD that was making my PC shut-down.
The proc. isn't heating much, when I play bf3 it get around 60 degrees (~140F)
The actual bios settings its full auto (default).
I have some knowledge in overclocking but I don't intend to do an OC with stock proc cooler unless just its for an slightly improvement.

What I need its a nice manual config to maybe stop with the "shutting down" issue.
I believe its bios settings due new windows installation, new HD, and I tested with other 2 power supply from Thermaltake and Zalman, the PC still shuts down.

The pc doesn't need to be stressed to shut down. I play BF3 and for hours the problem doesn't show... suddenly I'm at windows doing nothing and the PC shuts down... Other times when I'm playing... Its very weird..

Sorry for bad English, Im Brazilian.
Thanks for ANY help.

*NOTE: I'm just seeing the Windows Log Event and...
Here it says: Critical/ KERNEL POWER
The sys has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed or lost power unexpectedly

I was having a similar problem, and it turned out to be the fan on the power supply was not working intermittently. You have a really nice power supply, but you might check that and all you fans, clean out the system if you havent, make sure all the components such as ram, graphics card, etc are well seated.

I am no expert, but these are a few basic things to check. Normally, the things I would expect to cause random shutdowns would be power supply, motherboard, or overheating.

 

[GOEPOA]

Yes, I did a full clean-up yesterday, checked the ram, hd, vga, proc connector, cleaned the cooler... I mean, the PC looks brand new..
And about the PSU, the fan looks in perfect condition, it doesn't overheat as well while Im playing.
Im downloading memtest now to check if there is not the memory =/

ty

 

[Rvenger]

I'm betting its the RAM in this case. I have had a bad stick pass memtest on a few occasions. Start pulling sticks and testing individually.

 

[GOEPOA]

Ok Im on it. Going to test mem. right now.

Step 1, test all the hardware.

Use Prime95 or SuperPi (one instance per core) to stress test the CPU and RAM, actually HyperPi is a multi-threaded version of SuperPi and is probably the easiest to use, if you have instability there you'll crash almost immediately.

Use Furmark or 3DMark2011 to stress test the GPU, again if there's issues here you'll get crashes almost immediately. These will generally test the system under high load anyway so a good test for your PSU and mobo in general.

If you can't induce a crash with them, it could be software related, I'd suggest booting in to safe mode with your OS to stop all unnecessary drivers/software from running and seeing if it's stable for a length of time.

 

[KingFatty]

Yes, and even if the RAM passes the test, you can try to play a game with the RAM to isolate it. You have 3 RAM modules right?

Name each module 1, 2, or 3. Then, put in just 2 RAM modules at a time. So start with 1 and 2 in the computer. See if you get the error. Then, put in 1 and 3. Then try again with 2 and 3. Maybe you will find the problem goes away in one of those scenarios, then you know the other stick is bad. If your motherboard supports just one stick, maybe that's another way to try.

 

[Avalon]

I guess the question I would ask is...did this start happening immediately after you installed the new HD?

Generally if you add something new to the equation and start having issues, I'd tend to suspect the new item. Else if all components were existing and a problem developed, I'd go through the full battery of hardware checks to single out the troublemaker.

If this started happening just after you got the new HD, I'd diagnose that first to make sure it's not failing.

 

[Shmee]

sounds like CPU/memory/MCH related. As mentioned, try stress testing the CPU and memory, I recommend OCCT and/or linx/IBT as well.

 

[GOEPOA]

The problem was present before the new HD was installed...
Today I stayed 20hrs online playing bf3 and doing other stuffs... and It happened again.
I tried to remove the mems and turning the PC on. No results, the pc didn't switch on even with no memory, no HD.
Tried to put another VGA (GT250) that I have for backup, and didn't work as well...
When this shutdown occurs, and I tried to turn the PC on. He turns on and off for about 4 times, very quickly. Then it shuts off and don't turn on again. I have to remove battery from motherboard and let he "cool down" for some minutes.
Then to turn on I have to hold the power button (on mb) to turn on.

I will do the stress test with Prime and see what happens.
Thanks.

[GOEPOA]

Don't you guys think that, for the error in event log that says the shutdown was unexpected. This error its probably more related to PSU then to any other hardware?
Just guessing, when that kind of error happens, with mem, cpu of vga some error its printed on event log, or am I wrong?

 

[GOEPOA]

Well guys thanks for all help. I made all stress test possible, replaced VGA, mems.

But the problem, very weirdly was the 2 ATX PSU I had in my home.

I used a TX850W Corsair and an old Thermaltake 420W both of them had problems.

I'm using a poor EXTREAM 550W for about 3 days running with the PC stabled.

As I had problems with PSU before from Corsair Im thinking its the energy system of my building.

Im buying a XFX PRO 1000W.
Hope it doesn't broke that again.

Thanks.

That power supply is way overkill for what you need. Check to see if you can RMA your corsair, they have top notch support and will only cost you shipping.

 

[Rvenger]

I doubt the powersupply is even the issue.
