Hi.. Had a problem with my PC on Monday. PSU did some thing fruity and died a death. Whatever happened seemed to effect my m/board as well because when i replaced the PSU nothing worked (No keyboard / Mouse etc, USB so suspect some surge etc) Replaced the motherboard and had to reinstall XP. Since then i've been having blue screen of death with Driver_IRQL_NOT_Less_OR_EQUAL, Win32k.sys BSOD and Page_Fault_IN_NONPAGED_Area Personally i'm thinking the CPU could be up the nile. I've run the mem tests and they all come back A-OK.... But I know the mem test aint always 100% spot on. I've attached the dump files (Some of them from a few days ago some from today) and it seems to be crashing for different reasons today!! Let me know what you guys think!!
