Please Please Please help me out. I have been downloading alot of software from diffrent downloading networks. Now my computer won't open any jpg or mp3 files when I double click them. they don't appear to be associated with any programs. when I double click the files they change from blah.jpg to blah.jpg.exe. I can open my jpg's with photoshop, unless I have tried to double click them already. also, when I go to control panels, none of the icons open up to anything. i can open up the control panel items if i try to access them through help. is this fixable? am i going to have to reinstall windows? is there anyway to tell which program is the trouble maker?
