Something is wrong with my computer. Everything was working fine as far as I could tell until yesterday when I played some Supreme Commander and the game crashed at the end of a campaign. Afterwards, I noticed that IE was behaving oddly. Sometimes, new windows or tabs would just refuse to connect to the internet even though other tabs and windows work fine. I decided to restart, which is when I noticed a whole range of problems. I have Vista 64 Ultimate The following software now refuse to start, crashing immediately. Internet Explorer Firefox Windows Media Player Nero 8 uTorrent and Veohwebplayer just doesn't seem to start at all. Oddly enough, IE 64 bit works fine, as does the copy of WMP installed in program files rather than program files (x86). 64 bit WMP? Zoomplayer, Microsoft Office also work fine. Ironically, Supreme Commander and all my other games also work fine. When the things crash, the "program has stopped working, windows checking for a solution" thing pops up, resulting shortly in WerFault.exe-Application Error, "The exception unknown software exception (0*c0000005) occurred in the application at location 0*4b021750" This has got me completely stumped. Since I still can do pretty much everything I did before with 64-bit IE and the apparently 64 bit WMP, I'm leaving things alone until someone can help me figure out what the heck is going on. Using a Restore point from 2 days ago did nothing.
