Dear All,
Can anyone suggest any pointers for dealing with this problem? A colleague has a PCG-K315B which crashes randomly. The worst part is that it does not produce a BSOD, instead it appears to shutdown+poweroff instantly, usually just after booting. Our initial suspicion was that the machine was overheating and it has recently been taken apart and its fans cleaned. The problem continued. I have
reformatted the HD and reinstalled with a virgin copy of Windows XPPRO SP3+updates and installed the Sony drivers. The problem continued. I don't believe the problem is purely a Windows one, due to the
reinstall. Moreover, the machine is stable when running in Safe Mode & Safe Mode With Networking. It is also stable when running Linux (from a Knoppix Live CD). I have exhaustively checked the RAM with
Memtest86 and the HD for bad blocks, both of which are fine. I also tried exercising the H/W (HD/graphics etc.) from a Linux session to precipitate any thermal problem but without a result.
I an effort to get a crashdump I have tried turning on the various options;
Setting HKEY_LOCAL_MACHINE\SYSTEM\{CurrentControlSet,ControlSet001,ControlSet003}\Control\CrashControl\CrashDumpEnabled = 3 (minidump)
Setting HKEY_LOCAL_MACHINE\SYSTEM\{CurrentControlSet,ControlSet001,ControlSet003}\Control\CrashControl\CrashDumpEnabled = 2 (kernel dump)
Setting HKEY_LOCAL_MACHINE\SYSTEM\{CurrentControlSet,ControlSet001,ControlSet003}\Control\CrashControl\CrashDumpEnabled = 1 (complete dump)
NB: This has to be done from Safe Mode due to the crash/shutdown just after booting in normal mode. I can often get a minidump but the machine appears to shutdown+poweroff long before the other options
could dump to disc. Here is an example of the analysis (DebugDiag 1.1 (x86)) of a minidump (performed from Safe Mode). I was hoping for some indication of the where (ie. in a driver) the exception occurred.
The Minidump*.dmp file is typically left in eg. C:\Documents and settings\user\Local Settings\Temp\WER7c58.dir00 rather than in C:\Windows\Minidump [as specified in the CrashControl registry entries], due to the following shutdown+poweroff.

I also turned on the shutdown logging feature;
Setting HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Reliability\ShutdownReason = 1
but there are no shutdown events being logged w.r.t. the problem crash/shutdowns -- the power appears to go down so fast.
Just to check that the machine is capable of producing a BSOD I tried;
which produces the BSOD on demand as expected.
I also tried installing [from Safe Mode] the Omega Radion drivers (v.4.8.442) for the graphics adapter in place of the default Sony ones but the crashes/shutdowns continue.
Any ideas on how to proceed?
Thanks

Hi Tom,
We are not ignoring you - just stumped like you!
This is not a common problem. I have a K215M and would have noticed if we had seen the same or a similar problem over the years.
The fact that it is stable in safe mode would indicate a driver conflict and, as you have already checked, the graphics driver is favorite. I take it there is nothing showing up in device manager - even if you choose 'Show Hidden Devices?
Nothing in the Event Viewer Logs I suppose?
Sorry I can't be of more help - I hope someone else has some ideas.
Hi Blencogo,
Thanks for the tips. I had not thought to check the Hidden Devices but there was in fact nothing amiss there. There was nothing useful in the Event Viewer logs, not originally anyway. However, since installing the Omega grahpics adapter drivers I have seen the ati2mtag "I2c return failed" error described in http://www.pcreview.co.uk/forums/ati2mtag-gives-blue-screens-t2979037.html which looks suspicious. I am going to try turning off some Services and Startup feature using msconfig and see what happens. If I get anywhere I'll post it here.
Cheers

Dear All,
Here is the workaround I eventually found, which makes the machine usable. I'm pretty sure there is a H/W fault here, probably on the graphics adapter and associated with the power management (ACPI).
(1) Installed the ATI Radeon Omega drivers for the graphics adapter in place of the Sony supplied ones. Download file was ati_omega_xp2k_48442.exe.
(2) Disabled the power management using the instructions on http://www.sharkyforums.com/archive/index.php/t-127828.html. NB: in the Device Manager one needs to select
HTH anyone else with the same problem.
Cheers
Tom Crane.
