Hi.
I've been having an issue with my PC, which has started only recently.
It's running Windows 7 Home Premium 64bit, and there's a distinct possibility someone has tampered with the system. -_-
I tend to leave it running whilst I'm away, and I've started getting "Windows has recovered from an unexpected shutdown."
It's happened about five times now, especially when I'm running my MineCraft server, but I'm never at the machine when it has.
Here's the problem details:

==================================================JamesThat a fairly unusual error message. I'd suggest you try all standard troubleshooting steps:

1) Update all drivers if there is a more current one available  (your ati video card, sound card, ETHERNET card, chipset, etc)
2) Check for a bios update
3) Run checkdkisk: Right-click on a command prompt icon and open as administrator. In the command prompt window type:chkdsk /r  (then press ENTER). You'll be told the disk is in use and asked if you want to run checkdisk on the next boot. Say yes, exit the command prompt window, and reboot.
4) Download memtest (www.memtest.org), burn it to disk, and check ram
5) Run full scans with both your AV utility and MalwareBytes

Also, look in device manager and see if there are any errors please.
