Ok, so this is a confusing one for me. I was just playing a game that I play everyday like normal, and all of a sudden I exit out and my desktop icons look funny. They're all there, just no pics on them. so I try to open internet explorer and I get a msg saying that there is no file association for that program and to go through the default program thing to make one (I have windows 7, btw). But i can't even open that. Or literally anything. I did some searching and found some reg files to try to restore all of my file associations but when i follow the instructions to open the regedit without being able to open .exe files (going thru task manager and starting new task, or using the command prompt), it will NOT let me open it! I can't even right click the reg files and click "merge", the option isn't available! This is a two month old computer in great shape, and the only thing i can imagine is it got a virus. but I cant run my virus software or even system restore before it doesn't recognize how to open the programs and I can't change the associations like its telling me to thru default programs because I can't even open that. my computer won't open either and says "The parameter is incorrect" and I've gotten "No such interface supported" somewhere along the line too. Please help.
