old thread is practically my problem as well, mine started just yesterday after windy conditions caused a brief power interruption, maybe a second, 2 systems running, one with battery backup stayed up, zero problems, my other system went into BSOD booting reboots. Ironically, I have copies of the OS on other systems, pulled the HD to the faulty system, left the "faulty| drive in, redirected boot to the new drive, works perfectly, just had swap in a different modem (couldnt find compatible driver online), I could get online, played an online game, played a local game on it (its my serious gamer system) zero problems, switch to the bad drive,, reboot reboot reboot.
I can view and explore all contents of the bad drive in the good one, I have scandisked, repaired, did not do a fixmbr for the potential loss of data, I will copy the drive over first and see if the copy has trouble.
I literally want to find the actual problem on the "bad" drive. I tend to not believe its a hardware non-HD issue. I think some data got corrupted in the poweroff.
If I figure out where what, I may be able to copy over the files from the good drive, but the last resort is a new hard drive, but I have already bought a new drive as I planned to expand HD room on that system anyways. It runs fine as I type now with the replaced drive with the bad drive still intact.
system is my own custom build with AMD 3600 dual core 2G ram
