Hi, I started reading MDL and i feel that you folks would definitely be able to answer the questions I have. I definitely like this site so far. I started experiencing some errors awhile ago, frequent BSOD. I had someone help me with troubleshooting to the point that we found my RAM was not suspect. I haven't had help in over a week (I would link my original thread but I think there is a rule against that) so I started researching on my own. Through a few guides on trouble shooting BSOD and the usual causes I found a tool called "Who Crashed". I found out it was the OS that was causing the frequent crashes about 90% of the time. I had not updated windows OS (windows 7 Ultimate 6.1-64-bit) in awhile so it makes sense. I started to update windows (avoiding the WAT update which I have heard is the cause of much misery) and I got decently far. I updated to the point that the service pack 1 is now next to update with the prerequisite completed. However, now when i try to "find updates" through "windows update" it often crashes. When i do manage to get past that i start to download and then install the update. I never manage to get past downloading the update through the windows manager. To work around this I downloaded the service pack 1 from the Microsoft website ( File name: windows6.1-KB976932-x64). Upon attempting to install I got an error. To resolve this I went to the microsoft website and used the System Update Readiness Tool. When trying to run this i received an error code which the Microsoft website said was not able to be solved by the tool. The error code was: 0x8007000D ERROR_INVALID_DATA The data is invalid. So at this point the manual attempt of installation isn't working and I can't use the automated Microsoft downloader because that will cause a crash(has every attempt thus far). I'm not sure where to go from here.
