Windows 7: BSOD Issues

Hi!

I've been having this particular BSOD STOP 0x00000124 error for a week or so, but only whilst playing BC2 so far. At first I thought it might be overheating as one time there were unusual temperatures on one core of my CPU, but as I don't overclock and a couple hours of Prime95 didn't raise the temperatures much above the low 50s C. I then ran memtest for ~9 hours overnight, and came up with no errors. I've also updated every driver I can think of.

Somewhat at a loss as to what might be causing it.

My specs are

Gigabyte P67A-UD3 (Not B3)
Intel i5-2500k - Stock speed, not been overclocked
ATI Radeon 5850 1Gb - Also stock, not overclocked
2x 2Gb G-Skill F3-12800CL9-2GBRL
Seagate ST3320620AS ("320Gb")
WD WD5002AALX ("500Gb")

No cards in PCI/PCIe slots bar the graphics card.

In an Antec 300, with a Thermaltake 750W Toughpower PSU.

Dumps are attached.



Thanks for any help.
