ok so i have a Toshiba Satellite M(something) and there is something wrong with it and i cant put my finger on it......so here is what happens....i can start up my computer like normal and all my little things load up like aim, yahoo, and internet explorer... any programs i use that are on my desktop and have a desktop icon if i click them everything is fine.....but if i click a folder to try to get to some information my computer will close the folder and then all my desktop icons go away and i cant acess anything....i can press ctrl+alt+del and then open the same folder again and then every thing pops up again like normal but it will do the same thing if i try to open the folder again....any suggestions?

i can get any information you need if that can help you figure out whats going on.... btw i did a full sweep of my computer with Spy Sweeper and then i did a visrus sweep with Trend Micro Anti Visrus and all came up negative
