0x7b - 0xC34 - Win7 Pro 32bit
Let me first start up saying that this thread comes from a not-so-shabby IT tech, namely myself, that has worked on the issue for the better part of a week, having the resources of a whole lab at his discretion.
The system in question is my machine that i built myself and that ran (including reboots) successfully for a few months. After my last uptime of about 3-4 weeks was brutally interrupted by a power outage, the computer would not boot with a: "STOP: 0x0000007B (0xC997EA50,0xC0000034,0x000etc)" BSOD during the windows logo start screen. No "INNACESSIBLE BOOT DEVICE" error as i've seen on other threads, but i feel it's the same thing anyway.
A quicklisting of my system:
Win 7 Pro 32bit kept up to date, that ran on ACHI, hosted on a Samsung 830 SSD.
MSI Z77A-GD65 with latest drivers as according to MSI's website. (i have a slight speculation that this might be a cause seeing how the drivers were quite badly labeled there)
And the rest, not like it matters since it ran with them:
I7 2700k
4 GB DDR3
660TI
Let me iterate what i've done:
-Startup recovery - It actually errors on me with "StartupRepairOffline/6.1.7600.16385/Unknown/AutoFailover/29/Badpatch". Didn't go too deep into it seeing how i disabled a lot of Windows services and such.
-Safemode. Gets stuck on CLASSPNP.sys.
-Check for minidump using Bluescreenviewer in Hiren's MiniXP. Nothing gets created. This lead me to believe it really is having an issue accessing the harddrive after it loads, and seeing how it boots a lot of drivers until ClassPNP... this pointed me again to the Intel Drivers.
-I got a nbtlog to create, but given that i got there using totally unorthodox means (6months old backup sys32 thrown over), it's quite disqualified.
-For being thorough, i flashed my BIOS to date and triplechecked my BCD/fixMBR.
-Done the chkdsk etc and the SSD is in working order and uncorrupted, seemingly.
-SFC /scannow with offboot/offwindir from the RE and it said that it found corrupt files and successfully repaired them. The CBS.log didn't help me glean any useful info, but i attached it at the bottom for your perusing. I have a vague feeling running it from the RE was un-ideal. Later Edit: Nvm, ran it again and came up clean.
-I did create a fullbackup of my wininstall before i started messing around, so i have a 'clean' version.
-Various driver turn-around and tweaks ala: turn on IDE drivers(pciide), turn off AHCI (msahci plus anything with ahci in it's drivername and anything intel), which i did via Load Hive/Registry. - Nope.
-I attached a zip which contains a zip/XLS with what drivers boot up in 0/1 states, as in kernel/system boots, and the startup order.
-I also attached a zip which contains SafeMode bootuplists up until CLASSPNP.sys hang via glorious phonecamera acquisition.
-Everything that said on the first 5 pages of Google of various 7b searches.
-Spent more time on MSDN than i'd like to admit.
-Moved the whole disk over to another computer entirely and exact same error.
I let out a lot of parts since it's been a hectic week between work and fixing the same computer at work for 14 hours straight a day.
