Nothing to tell as far as I'm aware. The PC just stops functioning, no matter what I'm doing. No keyboard or mouse and if I'm doing something with sound, there is this buzzing noise that just about scares the crap out of me if I have the volume up.
Here is the kicker though, I did swap memory modules. Before the swap, I was getting BSOD's along the same periodic schedule. Occasionally and I do mean very in-frequently(been along time since my last episode) my video stops responding and refreshes itself.
And now for my final little quirk, for some reason every sixth or so boot, the Repair Menu comes up. I'm not sure why, when the PC was shut down properly the night before. All I have to do is tell it to boot normally and everything is fine. This didn't seem to start until after I purchased my 60GB Agility III SSD.
And to be honest out of all the systems I've had, I didn't seem to have BSOD's until after I purchased my GTS 450. BTW, the BSOD's spanned across two systems of which the GTS 450 and my 1TB Seagate HDD was the only common factors. I'm highly suspecting my graphics card but am puzzled why the BSOD's switched to freezing when swapping memory modules.
