My vista install started to crash when there is a lot of disk activity. It would crash every other day at first. Then, at some point it started to go down shortly after I initiate PowerUsenet downloads.
I looked at MS documentation for 0x0000007B and concluded that it had something to do with Sata controller. Article suggested to replace cables as it could be caused by a faulty cable but doing so did not help.
Then, I bought a HighPoint Tech TocketRaid 1742 PCI card. Documentation suggested to simply install the card and point to the driver location once Vista detected it. Unfortunately, Vista kept on blue screening once card was installed and I could not reach the logon page.
I installed the card on an empty PCI slot and connected back my Promise SATA controller. After the Vista came up I installed drivers, shutdown pc and removed the promise controller. Then, I reconnected my SATA HDs to the new controller and succesfully booted.
I hope this will end my BSOD issues....Time will show.
