Ok, i'll list the system and the specs.....

My problem is this. While the computer is on and this will happen at completly random times but mostly when it is in the middle of a game. The system will turn off and not crash or restart simply immedietly power itself down as if the plug to the computer was yanked outta the wall.

Specs:

Gigabyte SLI MB
2- BFG Nvida 7800 GTX
WD 200 GB SATA HD
AMD FX55
SB Audigy Gamer
16x DVDR
3 Gigs Corsair PC3200 DDR
Thermaltake 680w PSU
I have in it 4 case fans, 2 fans on the powersupply, 1 fan on the heatsink, and 1 xtra blower fan in the expansion slot.

I have tested the PSU and it seems fine. I get no warning that it is gonna shut down either it just turns off. I keep spot checking the temp on the cards but they never go above 66 degrees Celsius.

I am completely at my wits end its driving me crazy. Any ideas
 
How have you tested the psu? thats what it sounds like to me is a bad power supply. How old is this system? try swapping the psu out with another one and see if you have same problem
 
This system is brand new. Just built the other day. I brought it to the tech shop and they tested it with an atx psu tester said it was working fine. I wanted to swap out the PSU with my antec trupower 550 but it doesnt have a six pin connection for the Video Cards. THe Video cards shut down temp is 115 C and it just shut down at 78 C. Next question would be do the make an adapter for the PSU to convert a connection to the six pin. Or is there something else i am missing to check for the cause of problem
 
Ok,

New update to this problem....

I installed a new PSU and it happened again. I am now leaning more toward maybe a bad connection on the MB maybe with the SLI switch or something. Am i thinking crazy. I can rule out the overheating video cards(cuz they aren't hot) i am ruling out the CPU (its running cool as well.) To the best of my knowledge this cannot be a HD related issue nor the soundcard or DVD player. I am left with the possiblity of a bad MB.

Make sense to all of you?
 
Make sure you have the newest versions of every driver for your system.

I would also check to see if there is a newer version of the BIOS available from the manufacturer.

This might just be coincidence but every thread I have seen in the past couple of days with this problem has had a Creative sound card installed in the system. Try pulling that thing out of there and see if that solves the problem.
 
Really the sound card......

Never thought that would be an issue....

I'll give it a shot and let you know

Thanks
 
well i am trying everything now i have disabled the soundblaster and disabled the sli feature through the nvidia control panel and still the same problem. Could it be a bad motherboard it only happens when it is running a game. If the computer is just siting in windows i can run for hours upon hours a game starts up and longest i've got it to stay on was 1 hour


Any other thoughts?
 
New Update

I tried just 2 sticks of ram and it didn't work.

I took out 1 video card and changed it from SLi back to normal and that didnt work.

I tried multiple sticks of ram in different locations thinking it was a bad stick somewhere and that didnt work.

I added a blower fan underneath the video cards and that didn't work.

What am i left with. Could it be the CPU overheating and just shutting the computer off. I have the BIOS set to shut down at the highest temp setting and to warn me just before but it never does. I then set the BIOS to disable CPU temp and it still shuts down.

This shutdown is now also happening outside of gaming its happening in windows. My next thought is it something with the FX55 and windows xp.

I also have never checked out the hard drive. Its a sata connection. I don't see why it would be causing an auto shutdown.

Also all the fans in the system are stock with the Lian Li case. Should i just swap em all out for better ones and if so which.

The graphics cards are heating up at some points to over 80 celcius but that doesnt seem to ignite the problem since i have had shut offs at 57 degrees.

I am now completely outta ideas so any light you can shed on the subject would be great.

Thanks.
 
I have a crazy idea...

Go to your bios and turn on 'reboot after power failure' and see if it starts rebooting instead of shutting off...
 
Well, not to be a jackass, but you are using a Gigabyte motherboard so that right there is a good indication of your problem. You've really ruled out pretty much everything else. There is one more test though. Pull everything you can from your system and try running it that way. By that, I mean you should have connected:

Motherboard
CPU
1 stick of RAM
1 video card
1 hard drive

Nothing else, no CD drive, no sound blaster, nothing. If it works fine, then add hardware one piece at a time until you can replicate the problem and viola you have found the bad piece.
 
I have scrapped and run from just basics and yes it still did it and now i am running on a abit k8n sli board and not the gigabyte.
