As of last night, my computer will no longer allow any programs to open. This includes IE and all other web browsers. There is no error message, the applications simply fail to open. The hourglass appears as if a program is starting, but then it vanishes and the program never opens. I tried system restore, and that did not help at all. I am not very tech-savvy, so I am really hoping for a relatively non-complex solution. I very much want to avoid complete system recovery. I am wondering if re-installing Windows could fix this. Also, if I do re-install Windows, will I lose my data? Please help me. Any advice is greatly appreciated. Thank you.
