Hi there, Firstly i'm new to the forums as you can tell, so thanks in advance for having me! (I've tried almost everything! Trying to troubleshoot things in the past myself usually fixes the problem but i'm lost now.) I've been having serious problems with my PC recently and it's all came on so sudden. It started about 5 days ago and it's progressively got worse. I can't say for sure what's triggering them, it's just so temperamental. It triggers mostly with online gaming and varies between the two messages: Error code 1000007f, parameter1 0000000d, parameter2 00000000, parameter3 00000000, parameter4 00000000 Error code 100000d1, parameter1 00000000, parameter2 00000008, parameter3 00000008, parameter4 00000000 I've tried updating all my drivers, Graphics, Sound Card, Motherboard/Chipsets and nothing's resolving this issue. I'd really appreciate any help for where to progress next... thanks!
