Does the message tells you specifically that is a hardware failure? If not, "Stop 0xC2 or BAD_POOL_CALLER" Blue Screen can also be caused by a faulty driver or software recently installed. If you can, start the PC and press F8 immediately once per second to get into Booting Options and choose Safe Mode. If you get Windows started without any problems then it's a device driver or software causing the crash. Post back,ok? Good Luck!
