And finally I think I might have started having a thermal problem as summer set in... I built when it was still cool...
Does the video card interact with the CPU via the NB? Or does the Video card affect the NB in any way? Cause if so I also switched drivers on my GTS and I OC'ed higher...
Then finally... every time I froze up and had to power off had the chance of corrupting important OS files that may have added to the instability problems...
I ask again cause I can never get anyone to answer this question other than Charger who already weighed in on the issue... May I have permanently damaged my NB?
The video card theoretically does weigh in on overclocks. This is one of the reasons that linkboost was removed from the bios in the latest revisions. It boosted voltage through the pci lanes to increase the graphics cards voltage (and supposedly its speed. it was like a mini overclock). That is also the reason I recommend disabling Nvidia GPU Ex as it has a similar effect. So to answer your question, it can affect it. Also, your graphics card may be on the same 12v rail as your cpu and as such the extra draw could be pulling more than the line can stably support. I believe your antec has two 12v rails?
You absolutely have to reset your bios settings to stock when changing the bios revision. The board will try to keep your overclock settings when changing bios but the newer (or older bios if you are back flashing) bios may not be stable at the settings the other version was working at and yet it is being forced to run at those settings (which technically can't happen when you are going in and out of the bios to overclock. If you hit a setting that doesn't work, it crashes or locks up, etc and you reboot and try something different). The short answer is that it can damage the board (And there have been reports of this on the asus forums).
Can you have permanently damaged your NB? Sure, its possible. I have personally fried an NB on a system I built for a friend with this board. We were using a coolit freezone tec for the cpu overclock and water cooling for the nb and sb and graphics cards. While running orthos overnight, the pump on the water cooling system failed and crashed the system eventually. When I rebooted the system in the morning, everything seemed fine at stock settings. If i tried to increase the nb even .1 in voltage it crashed every time. We rma'd the board and got a new one but the nb was definitely pooched.
Can restarting crashed os cause instabilities? Yes in windows it can. You could corrupt one of the system files and it was cause all manner of problems. Sometimes a system restore can resolve this and sometimes it can't/
Hope this helps
