Hope someone can help with this:
I have a Dell Studio XPS8000, Core i7-860, 8GB RAM, nVidia GT220, Win7 Home Premium 64-bit OEM which, more or less since new, randomly crashes about once a week if I leave it alone and powered up for several hours or put in standby first. When this happens the PC is either fully shut down (& I then boot selecting 'boot windows normally' option) or has rebooted to login screen automatically.
According to recovery boot it is a BSOD, and each minidump file looks like nearly identical to this, parameter 1 always 0x00000003:
Dump File 041010-18891-01.dmp

Processors Count 8
Major Version 15
Minor Version 7600
Win 7 is fully patched, all Dell recommended downloads applied, and I have latest video drivers direct from nVidia (another thread suggested these as a problem).
I am running McAfee Security Center, Office 10 Beta, IE8 64 & 32 bit and Google Chrome and usually nothing else.
Network card is Dell Wireless 1505 Draft 802.11n WLAN Mini-Card over an 11g network.
As said, this only happens when I am away from the machine or it is in sleep.
Thanks in advance
