I have been trying to troubleshoot the constant crashing with Crysis 3 and Origin since it was available for download which I had major difficulties in doing because Origin keeps becoming unresponsive and says "Origin has encountered a serious error and must close".

Of course EA has been no help whatsoever, it is not just with Crysis but other Origin games but Crysis 3 seems the most severe out of them all.

When playing single player, it doesn't matter how long maybe 10 minutes after running the game or 1 hour (if I am REALLY lucky) the game and Origin client crash independent of each other, it has even caused me to have to hard reset my computer as it becomes locked up. I have also had the DIGI DEVICE REMOVED ERROR, followed by a BSOD.

The main frustration is with the Multi-player, I will be randomly backed out of the game I am playing in, which most of the time I never get to bank my EXP or crashed to the desktop while Origin tells me it has crashed.

Then I will have to restart Origin and Crysis 3 because the game cannot find any servers after that and my ping will go through the roof (upwards of 350) from the first instance of entering Multiplayer. To quit the game I have to CTRL/ALT/DELETE because the menu in game zooms out and becomes dark and I cannot click on the quit button.

The game is allowed through the required ports in my firewall and so is Origin, I stopped using MSI Afterburner while running either application as it is a crash fest every 2 minutes, other programs which are not needed are closed also.

My PC specs are:

Intel i5 2500k (overclocked to 4.5ghz, but also tried running stock clocks, no difference)
Nvidia GTX580 in SLI (usually overclocked also but MSI Afterburner makes situation worse) been using 310.XX 314.XX and new beta driver 314.14, all the exact same issue.
8GB RAM
Windows 7 64bit

On Windows Event viewer it states:

Level Date and Time Source Event ID Task Category
Error 09/03/2013 13:22:11 Application Hang 1002 (101) "The program crysis3.exe version 1.2.0.0 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.

Start Time: 01ce1cc84d7c27dc
Termination Time: 90
Application Path: C:\Program Files (x86)\Origin Games\Crysis 3\Bin32\crysis3.exe

If that all was not enough I also get the Cry Engine Error, allocation of ******* bytes failed.

I can't say how frustrated I am with Origin and this constant barrage of crashes, I am totally lost as what to do now, I have ran out of ideas and EA is no help as they haven't bothered to reply since launch day.

Any help / ideas would be really appreciated!!

for the bsod can you run http://www.resplendence.com/whocrashed and post the dump report.

also try running only on one gpu as sli has caused problems for some in the past especially people with 5** cards.

also try a slight underclock and see how that goes.

i cant advise much more as ive not had any problems at all.
