W7 restarting randomly - No BSOD

[rmartignoni]

Hello! My computer started restarting randomly about 2 weeks ago and this problem is getting more frequent now... I don't get any BSOD and the event viewer will log only "Event ID 41 - Kernel-Power"...

My computer just turn off as if I had a power-loss and then turn on again... The strange is that it's totally random... I can play games for more than 2 hours ou run a stress test for 3 hours without restarting but I can turn on the computer and when browsing the internet for 5 minutes it will restart...

I have made a lot of research on the internet but didn't any relevant information but a PSU problem...

All the drivers are updated...

Here is my setup:

Zalman 360w
Gigabyte GA-P67A-UD4-B3
Intel Core i5 2500k @ 4.5GHz
2x 4GB Corsair DDR3-1333
eVGA GTX 550 Ti 1GB
2x Seagate Caviar Blue 500GB SATA 3

What do you think? Should I replace my PSU or this is a know issue on W7?

360w PSU is way to low for that setup, I would get a good 650w PSU.

650 is overkill, but i'd happily agree that 360W is light.

Doesn't explain why it does not gail when being stressed, are these cpu + gpu tests that you run?

I've similar problem with my PC. Ever since I bought my PC two years ago I got random crashes with no BSOD.

During the two years I've changed the graphic card, PSU, new memory, new SSD for the OS and reinstalled Windows 7 several times, but still I got the crashes. I've also run memtest without finding any problem.
So, my problem is probably related to the mother board, the processor or any driver.

My PC:
- Asus P6X58D PREMIUM
- Intel Core i7 920, 2.66GHz
- Corsair 12GB (6x2GB) 1600MHz XMS3
- ASUS GeForce GTX 560Ti 1GB PhysX CUDA
- OCZ SSD Octane Series 2,5" - 256 GB (used for the OS)
- 80GB 2.5" SSD Intel X25-M G2 SATA
- HDD Hitachi 2TB
- Fractal Design Newton R2 650W PSU

nothing in c:\windows\minidump?

either of you?

 

[mackanj]

Nope

 

[13thmonkey]

have you got control panel > system > system > advanced > startup and recovery set to create a minidump?

 

[mackanj]

Yes, I have, but no minidump is created.
The only thing the Windows log says about the crash, is that the PC has been abnormaly turned off.

 

[13thmonkey]

please can you start your own thread maolas, and provide a lot more information.

 

[rmartignoni]

I found the problem.... it's the adaptative power management setting implemented in the newer nVidia drivers.... I just changed to "max performance" and it never crashed again....

 

[mackanj]

Where do you set "max performance"? In the NVIDIA or Windows control panel?

 

[rmartignoni]

yes, on nVidia control panel under "Manage 3D Settings"... in the global settings set the power management mode to "prefer maximun performance"...

Thanks! I'll try it
