Hi, About 6 months ago, I installed a module of 1gb 667 RAM (had 512mg 533 RAM before). The computer that has the error is my son's and he plays a game called Lineage2. Since the new RAM was installed, he has been always getting BSODs, about two-three times a day. Due to his complaints, I tried removing the 1gb module, but the BSODs keep appearing, always giving the same error (1x07 memory thread exception handle). After reviewing the computer, I tried to reinstall the game in the hard drive of my computer and plugging that hard drive in my son's, but the BSOD kept appearing. I suspect that the problem can be in the old RAM module, but it has always worked fine. I attach the last 6 minidumps, because I can't understand the text of windbg, to see if you can help me. Thanks a lot for your time. PS: Sorry for grammar, my english isn't very good.
