Hi guys.
My custom built rig has served me flawlessly the past 3 years. The other day I experienced a sudden BSOD code 124 while rendering a video, and now it won't boot.
The post stops after initializing the HDDs and the screen remains black while nothing more happens. The Q-code on the board shows "b2" and the "boot device" LED remains lit. No indications of a memory failure. I've switched to the second BIOS (with default Asus cfg), replaced the video card, but it didn't make any difference.
Given that the rig was working fine just before the crash, I wonder what could have failed. I suppose it could be the CPU but I kind of doubt it. It never complained or caused any troubles prior to this. Disassembling the rig to get to the CPU (e.g. to try reseating it) is a huge project, and I'm not sure it's worthwhile the effort.
I'm not exactly a novice and I always have been able to get around such problems before, but now I feel a little stuck. I'd like to avoid stripping down the build and starting from scratch (it will be like building it up again), and I'd like to try a few things before doing that. My "intuition" is telling me that it's probably something "stupid" getting in the way of the booting, especially giving its flawless function until this crash, but I just can't figure out what this "something" is.
I'd greatly appreciate a good advice. Thanks!
