Blank screen after xp splash screen and then hangs
My colleagues and I work in a tech environment and we have seen several computers with the same symptoms. Namely a failure to boot xp. After the xp logo screen the screen goes to blank and it just hangs.
This looks like a graphics card fault but changing card does nothing.
Booting into safe mode and it stops at agp driver.
Repairing windows gives a lsass.exe error which cannot be resolved.
Scanning hard drive reveals no viruses.
So far we have had to reformat and reload xp - but I just got another computer with same fault symptoms. I'm wondering if anyone has similar findings and have they discovered cause/fix.
There is a small possibility that an av update may have been cause, but no way to confirm this.
