Hi all,

Having some BSOD issues with the setup below.

- Gigabyte Z77X-UP5 TH
- CMZ8GX3M2A1600C9
- i5 3570k - offset overclock stable at 4.5ghz
- Enermax NAXN ENM850EWT
- Sapphire HD 7750 Ultimate
- LG CH10LS28 - Blu-ray drive
- AK-HC-05BKV2 - 5.25 memory card reader
- Corsair 550D Obsidian - case
- Western Digital Caviar Green 2TB WD20EZRX
- Samsung 840 Pro 128GB
- GC-WB300D - wireless PCIe card
- Win7 Home Premium - not yet activated

PC is rock solid when on, but sometimes has small issues shutting down. It either hangs on the 'shutting down' screen for around 30 minutes before giving me a 0*0000009F BSOD...

...or it shuts down at a normal speed (few seconds from telling it to shut down) but immediately gives me a 0*000000C5 BSOD.

Neither happens all the time (at least 50% of the time it shuts down fine), and there are no other BSODs , just 9F and C5 errors. The most annoying thing is that no minidumps are ever created - presumably because these BSODs occur when Windows is already 'done'. All my minidump settings are correct (matching those described here - http://blog.nirsoft.net/2010/07/27/how-to-configure-windows-to-create-minidump-files-on-bsod).

So... any websites/ tools/ pointers on how to diagnose these BSODs without access to minidump info?

May also be worth mentioning that the memory has been thoroughly tested, and this issue also occurs when the PC isn't overclocked.

Thanks,
Rob
 
first one is a driver that is changing its power state without completing its pending IRP. I would look for a updated ethernet driver. (maybe a usb driver )

second one is a driver attempting to read from a bad memory location..
Bug Check 0xC5: DRIVER_CORRUPTED_EXPOOL

both could be caused by a driver corrupting shared memory structures used by other device drivers.
most often it will be a non microsoft provided driver. Microsoft provided drivers are updated via windows update, 3rd party drivers require the enduser to look for and manually install those updates. (does not happen until something actually breaks)
