Bluescreen when idle

[liltwix]

Recently, I upgraded some of my hardware, the parts are listed here: http://www.tomshardware.com/forum/327286-30-upgrading-intel-board . I did a clean install of Windows 7, but recently I've been having a problem when leaving my computer 30 mins or so. I get back, and on the screen there's a prompt saying "Windows has recovered from an unexpected shutdown". This is the details of it:

I haven't had a blue screen during an active session, and I've been playing games for hours at a time. Any ideas as to what the problem is?

That bugcheck code is KERNEL_DATA_INPAGE_ERROR. It means the system was unable to read in a page from the pagefile into system memory. Parameter 2 is the status of the I/O operation that failed which is STATUS_DEVICE_NOT_CONNECTED in this case. From the failure status, it seems like a SATA controller or HDD issue. It could also be RAM-related. I also notice that you're not running SP1; you should definitely install the latest updates.
