Was running on Windows vista Home Premium 64 bit, but recently have made the switch to Windows 7 Ultimate 64bit. Running a Nvidia GTX 260, Drivers are up to date. Never Been Overclocked. But recently have been getting A Fatal Pink Screen of Death Error that crashes the video of my computer, The sound continues for an average of 30 then crashes also. It is more of a Pink/Green mess of pixels. Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1033 Additional information about the problem: BCCode: 124 BCP1: 0000000000000000 BCP2: FFFFFA8007D518F8 BCP3: 0000000000000000 BCP4: 0000000000000000 OS Version: 6_1_7600 Service Pack: 0_0 Product: 256_1 That is the latest Error Dump I have recorded. This error only seems to occur only when playing recent games (Fallout New Vegas, Left 4 Dead 1 & 2, Deadspace 2 etc) And doesn't seem to occur on older or more simple games. (Medieval 2: Total War, Minecraft, Super Meat boy) I am wondering if it is my Graphics Card over-heating, As the fan is only at 40%. (1400 RPM) My Case is a Thermaltake Armor+MX. I will attach as much information as I can collect. Any help or advice would be much appreciated. Kiwi Gamer.
