Huge problem with random reboots and no boot.

I just built my computer a couple of days ago:

Asus A8N-SLI Premium
AMD Opteron 165
XFX 7900 GT
Hiper 580w PSU (I think this is the problem)
Corsair XMS DDR 400 (2x1GB)

My computer worked great for a while, then when I started up Oblivion on high settings, it rebooted randomly on me. I tried again and another reboot. Ok... so I tried to play a bit of Quake 3, reboot after 15 minutes, again and a reboot right away, once more and a reboot after 3 minutes. I also just tried to check my event logs and had a reboot while trying to do that.

I did get to check my logs, I saw no dumps at all, nor any references to dumps. There is no BSOD, just a reboot.

Now I can't even boot at all. I get nothing on the screen.

Help sorely needed!
 
I'd strongly lean toward you PS being bad/weak. Swap it out and hopefully that will solve the problem.

Other than that, you could have a bad Vid card or bad mobo.

I checked temps with them just in case, but they seemed to be just fine.

And wouldn't I normally see some artifacting before a reboot with my vid card?

Edit: Tried to run Memtest86, it rebooted about halfway through.

Seconded. Minus the video card imo.
 
Another for a bad PSU/MoBo.

Strip it down to minimum spec to lower the load on the PSU.
Remove all cards bar the vid card.
All drives bar one to run memtest from.
Etc, etc.

If it still reboots then its leaning towards the mobo being bad.
If it runs 3 loops ok then I would lean towards the psu being weak.

Luck........ :D
 
I'm trying an alternate psu right now along with memtest, I'm gonna let it run a couple of passes. Lets see what happens.
 
\Ran Memtest and it found no errors. Tried to load up Oblivion again and it crashed.

I only have my dvd burner, 1 hd, mobo and vid card hooked up. I also have another PSU that I know works properly.

Now I'm trying different ram. 2x512 OCZ ram. It was unsuccessful.

So, known good ram, known good PSU, Vid card is good, CPU is good?... mobo autoshutting down?

Edit: Tried to run Quake 4, got to the to the Server Select screen then a reboot. It seems that it reboots when something is intensive. CPU?
 
Seems all that's left is the motherboard, or possibly CPU.

Have you checked the CPU temp? Quite a few boards will either shutdown or reset the system if the CPU overheats. Open the case when it's on, hold on to the case, and touch the heatsink. How warm/hot does it feel? Are you using the stock heatsink? No overclocking?

I'm using a Zalman cnps9500. CPU temps read 37-42c idle depending if I have the front on or off.

Heatsink seems rather cool, right now I'm running a Prime95 torture test. and it's gone good for about 30 minutes now. I'll give it a bit longer and if everything works out well, I'll send back my motherboard.
 
Have you tried diff vid drivers? Maybe something is pooched in there and causing windows to crash.

Runing the torture test will put a heavy load on the CPU which is good for testing out all the math functions but it won't test the vid card which is what this issue seems to be tied to.

You could also try re-arranging the power cords in your case to isolate the power being provided to the vid card from all other devices.

Do you know anyone else with a similar config as yours so you can try your vid card in their system? That's about the only way you'll be able to completely eliminate that from being the cause.

I'm using the newest Nvidia drivers. 84.21. I've already isolated the power to the video card. Unfortunally I don't know anyone else with a similar setup.
 
Try rolling back to a previous version or patching your oblivion.

/stop hacking Oblivion to see boobies

Hah, the problem isn't just Oblivion though. It happens with other games too.

And what I do with the ladies of Oblivion is my business.

Argonians... :eek:

Edit: Tried reloading the video drivers and had the same problem.
 
Just out of curiosity, I tried to reinstall windows.

Reboot.
