Right now I have the problem of PFN_LIST_Corrupt Stop:0x0000004E Before I though is the Ram problem, but it seem 0 error found, I also have tested 4 pair of different ram, all go the save BSOD. I downloaded the dumpchk, when I try to install it, another BSOD comes up. I have no idea what's going on . I have updated all the driver all the motherboard , dvd rom firmware.
