Frequent post-patch crashes/reboots from game

Russkly · #1 04-09-2011, 12:56 PM

The patch has definitely been an improvement for me (and response duly posted in relevant thread), BUT:

Now getting more crashes/reboots than pre-patch (where it happened but was fairly infrequent).

Can even happen just while taxiing or when flying over water or countryside/towns.

This is obviously very worrying.

Windows records it as an Event 41 Kernel Power error.

I had overclocked my CPU, so I reset it back to defaults - same problem.

Turned off HyperDrive via the ASUS SmartDoctor software - same problem.

Increased CPU temp. threshold to 60c in BIOS - same problem.

Noticed whilst in BIOS that CPU temp was below 50c, but IOH was 75c, so I don't think it's a temp issue(??).

PSU is rated at 720W, so I'm hoping it's not that.

Lowered graphics settings gradually after each crash/reboot, but still happened with everything low except Model Detail, Damage Decal (both high), Land Detail (medium), roads and shadows on, and grass off.

Not seen this with other games, even RoF on maximum settings.

Any ideas, because it's definitely more frequent since the patch?

BTW I have searched the forum under "reboot" and "crash", but couldn't find any similar problem (at least not without searching some of the larger threads!).

I'm experiencing similar problems, except sometimes I get display driver stoped working but has been recovered,

pre patch I did not have any problems and had good FPS over land and sea with lots of aircraft, London was a slideshow.

after patch my FPS is great, and flying over london with most things on medium and models/damage/effects on high..except launcher has stopped working and the occasional message that the display driver stoped working. I had changed nothing except installing the latest patch.

Someone reinstalled MS Framework .4 and solved his issues with that, but I have not been able to play with my system since yesterday.

Thx. I'll try that.

Not getting any launcher (not anymore anyway) or display driver error messages though - just crashes and then reboots itself - very dramatic.

Sometimes happens within a few minutes of starting a mission, sometimes 20 minutes in.

Can happen anywhere, not just over cities, for example.

Perplexed and slightly concerned, because that's a pretty serious thing for a PC to do!

Exactly the same problem here!

Win 7 64bit. Nvidia GTX470 card.

Game plays for a while then PC reboots without any warning.

Installing msi afterburner improved things a bit - I can speed my GPU fan up and keep it cooler but the game still reboots the PC after a while.

COD hammers the GPU..99% ALL THE TIME even after the patch.

I do hope they solve this. Makes the game unplayable for now.

Interesting info, sizequeen.

So, in your case, it's the GPU getting fried? How do you tell?

Mine's an ASUS card which comes with its own management software (ASUS SmartDoctor), and and at the moment all the cooling is on "Auto".

I might try fiddling around with those settings tomorrow.

I don't think it's the CPU, because when I go into BIOS after the crash/reboot, the CPU temp. is <50c with IOH @ 75c.

Let me know, if you get round it.

Hi Russkly

I'm not sure what is causing the Event 41 Kernel Power error message.

I'm guessing it may be related to the GPU (graphics card processor) getting hot and tripping the power to the PSU. I'm pretty noobish with these things however.

My main CPU temps are fine.

I installed a (free) program called msi afterburner http://event.msi.com/vga/afterburner/download.htm

This monitors your graphics card and allows you to overclock/change fan speeds etc. I mapped the fan graph in it to speed up to a higher RPM than it was before. This has stopped COD crashing/rebooting for around 10-15 mins. Before it was rebooting in game every 5 mins or so. The program also shows you how hard your GPU is working in game.

Thx.

I'll try altering the settings in the ASUS software, so that it focuses on cooling rather than on max. performance.

No other game, included maxed-out ARMA2 cause this GPU problems like this though.

Ho hum.

Do let us know how you get on.

I'm still fiddling with settings as well!

Neither have I ever had these problems before. This system is only 6 months old!

A bunch of people (including me) had this problem pre-patch.

There are some fixes in this thread:

My issue got fixed, but I know not how!

Now I have a new problem after the patch...
