Frequent post-patch crashes/reboots from game

@whiplash: No, still on 1.00.13 patch. Will try the new one as soon as it's final

No, I don't, but it would be useful, if someone else knows of some software to do this.

I wonder if everyone else's GPUs are running at 100%. If they are, then it would imply problems with the game programming, would it not, and then exacerbated by PSUs not up the task, hence the reboots for some of us?

Done some testing.. after 10-15 min of gameplay... reboot over and over again... Issue not related to nvidia drivers I'm afraid.... GPUs stay at 100% for me also.

Asus P6T
I7 920 no o/c
GTX580 no o/c
12 gb Ram
630 W PSU

Any windows error records?

Hi,

I have also found an issue with the PC suddenly shutting off*. I have come to the conclusion that this is due to the graphics card over-stressing the PSU. The indicator is that the switch off is instantaneous and nothing is logged as abnormal. This is because the system is shut down before the OS can log what is going on. The next entry int the event log was the system starting again.
What is happening? - the PSU has an "overcurrent shutdown" feature which acts like a fuse and shuts off all power rails if one of the rails starts drawing too much power.
Cause - I upgraded my graphics card without paying enough attention to the rating of my PSU.
How to check? - run a GPU benchmark that stresses the GPU, this should also provoke the shutdown.
This is not a "crash" or driver incompatibility as it has occurred with several driver versions.

OS: XP 32 bit SP3
CPU intel core2 duo @2.83GHz
Memory 3.25 Gb
GPU: MSI N460GTX
PSU max 19A on 12v rail

*depending on BIOS confic,such a shut-down may cause automatic restarting.

Hi Swiss,

Yes, as posted at the start of this lengthening thread, I was/am getting a "Kernel Power Error 41".

I looked it up:

http://support.microsoft.com/kb/2028504

...and, if you look under the "Resolution" section, it does indicate a PSU problem.

It probably matters less with games/software that don't max out a major power-hog component like the GPU, but CoD clearly does push the GPU very hard indeed, so perhaps it is the combination of maxed-out GPUs and slightly weak PSUs that's causing us the problems?

What Jetski is saying seems logic... will upgrade the PSU to 800W and let u know. Checked mine... 12V 22A MAX
Thank you

Thx, Jetski.

Makes absolute sense and fits my suspicions.

I recently changed the PSU fan and did wonder about the amperage rating compared to the GPU spec., but left it, because it hadn't caused any problems before (largely on Rise of Flight and Arma 2 @ high settings).

Only CoD has stressed the system enough to expose the weakling PSU.

OK, time to fork out some more cash on a new PSU to be followed shortly by a new GPU.

Ho hum.

Interestingly I can't find any PSU at the local on-line shop I use here in Spain that has PSUs with 40A on the 12V rail - max. seems to be 25A.

Anyone know any manufacturers that make PSUs to handle this kind of loading?

Please get a decent one(~$120+), not some cheap crap.

Well, the ones I was looking at were mostly Antec 850s and 1000s and were about €150-250!!!

They still only had 25A max. @ 12V.
