Im not sure what happened to my machine over the last week or so, it seems to have gone into meltdown. Windows installed some updates then suddenly after restarting it would give the blue screen of death just before the login screen. After a few times of doing this it booted into recovery mode and attempted repairs on the machine, it seemed to have worked and I got into windows and surfing. All of a sudden it gives me an error box in the screen taht keeps re appearing if I click ok, it was an error about net framework missing a dll. I searched a bit around and found that net framework 4 might be a problem and to uninstall and then re intall it, I tried to unistall it but if gave me an error that it had parts missing and couldnt continue. I ran windows update again thinking it might be able detect a failed update and fix it by reinstalling what ever had gone wrong. After it did a few the computer restarted again and again I got the blue screen of death just after typing in my windows password. I then again got to recovery console and tried to repair the prolems and went back to windows when it was finished. Dont think it fixed it properly as when I run windows live messenger the opening window is just black and I cant select or see anything, I even tried to reinstall windows live messenger but the problem stayed. I also dont seem to have sound, all the devices are working normally and I checked the device manager console. When I ry to test the sound by configuring the speakers it gives an error saying unable to play sound. I have no idea what the hell happened all of a sudden, it was working fine so far. I usually hibernate until I need to restart so Im not sure when this actually happened or what caused it. If anyones got any ideas please let me know. Additional info, for some reason I cant even see previous restore points to restore back to, it only has the ones for the windows updates I just did yesterday, even though I know I installed itunes last week and it should have one for that. Windows update also keeps showing the same file to update everytime, not sure what it is called as Im not at home, but I guess its not installing properly or is the one that was previously updated and started the problems. Can anyone help with this. As the only option I can think of otherwise is to reinstall Windows and I dont really want to do that, but might have to if I cant get the sound to work or stop the blue screen.
