A friend convinced me to have a look at his 32 bit emachines ET1161-07 tower running Vista SP2. It blue-screens pretty much if you just look at it nasty.
It started out with a IRQL_NOT_LESS_THAN 0x0a screen just on booting. I'd get to the 'Windows could not start...' screen where my only options were Startup Repair or Start Normally. Normally never works, sometimes the BSOD above, sometimes just hanging for hours on the splash screen. On one of the few times Startup Repair DIDN'T blue screen, it said it could not fix the problem. Advanced options to the command prompt allowed me to run do a dismoumt and chkdsk /r. It found some errors and corrected them.. A restart just took me back to the repair or normal options again.
I've also gotten to the prompt and done a bootrec /fixboot as well as a fixmbr. No change.
I have 3 Vista 32 bit disks. I have tried all of them. Sometimes I get the IRQL screen after loading files is complete. Sometimes I get a PFN_LIST_CORRUPT (0x4e) BSOD, sometimes a MEMORY_MANAGEMENT (0x1a) BSOD. Sometimes I get a BSOD without a heading, just saying that a problem has occurred (0x7e). One time with one of the disks I was able to do a system restore to last week. A reboot took me to thse same 2 options.
Only once did I achieved a complete start of Windows that held for more than 15-20 seconds. Than time I opened an elevated prompt and attempted to run sfc /scannow. I got to 52% and died with no cursor movement, no taskmgr response, nothing.
My friend doesn't care about saving anything on the PC, so I used a Partition Wizard disk. I get to the boot choices, but booting into Partition Wizard stops and becomes unresponsive after a few minutes. I let it sit there for almost an hour. Nothing.
Obviously I can't perform the steps you'd like me to take because it won't boot. Should I be removing the drive and slaving it to another PC? And then formatting from there? Or what? I have no ideas...
