I have managed to get onto the hosting site, so I have attached the minidumps in case someone else cannot access them. Each of the three dump files are different, but they all reference the same file and address, ntoskrnl.exe, and they all happened at the same time. STOP: 0x0000000a IRQL_NOT_LESS_OR_EQUAL Probable culprit driver:
ntoskrnl.exe STOP: 0x00000050
PAGE_FAULT_IN_NONPAGED_AREA Probable culprit driver:
ntoskrnl.exe STOP: 0x000000c5 DRIVER_CORRUPTED_EXPOOL Probable culprit driver:
ntoskrnl.exe Probable overall cause:
I would really check and update ALL of your drivers
in particular your grapics and network cards. Don't miss any out, and make sure your copy of Windows and your anti-virus is fully updated. Make sure the games you are playing, and lightroom, are also fully updated. It is also probably worth running a memory testing tool and chkdsk.
This may not be an option, but if you have a wireless network card, and an ethernet port, try the other one (ie. If you normally use the wireless card, use the ethernet port, and vice versa). Now disable the one you normally use, and try your multiplayer game again. Tell us how it goes, but it will probably just lead us to nowhere. Make sure you update the drivers for both of them.
