Am getting a BSOD 0x19 on a frequent basis. Sometimes several times a day and then nothing for a week. The only common feature that I can see is that I'm always running Outlook (2007 SP2) when the system crashes. I have run Scanpst to ensure all the PST files are OK. And I have repaired MS Office. But that hasn't fixed anything. I have run memtest, chkdsk, etc., and all is OK. I have tried windbg, but am unable to get to the bottom of the problem System: XP Pro 32-bit SP3 I have attached a minidump file. Any help would be greatly appreciated.
