My dad just bought this new laptop about two weeks ago - it's a Sony Vaio CR240N, if it matters. He asked me to blow it out and put a fresh copy of Vista on it, since it was so slow, because of all the bundled software that came with it. Its been working fine for me, but he's noticed that its bluescreened for him a few times, and sure enough, there are four minidumps saved (which Ive attached - can someone with a good set of symbols take a proper look?) I analyzed all four, and all four told me that it was probably caused by ntkrnlpa.exe, so I did a google search on that. I found a lot of people had the same problem, but all the fixes were extremely generic - scan for viruses and spyware, etc. No one actually had a proper fix for it. When I first installed Vista, I installed all the programs and drivers from Sony's web page, so that pressing the Volume Up/Down keys would show up on the display, and things like that. I did a windows update afterwards, which showed no new drivers. (I just did one today, and its downloading one new driver right now, titled "Intel - Networking - Intel(R) Wireless WiFi Link 4965AGN" so if that is what is causing my bluescreens, please let me know ) Anyone have any ideas or things for me to try, other than the obvious (virus and spyware scan, RAM test, etc)? Also, would someone mind checking over the minidump files? I set up Windows Debugger according to MajorGeeks, but it kept telling me my symbols were wrong - probably a result of my horrendusly slow internet connection.
