I work in a pc repair shop and have gotten stuck a few times with machines that suddenly get 0x0000007E errors. I actually have two in the shop right now with them. They booted fine, I ran a few virus scans on one and removed norton from the other and now dead in the water. Things I've attempted: Tried removing all the none stock drivers from the windows\system32\drivers folder Attempted repair install, same error CHKDSK /f Memtest & HD tests, both passed I'd really like to find a way past this error, I've had a few machines with it in the past in here and we've just ended up forced to do a Fresh Install almost everytime. Yes I've googled the code and read the various posts, sadly not many of them have a solution other then reformat. Since I started a repair install on the machines, safe mode is not an option. The two machines have different specs entirely, though both sata hard disks.
