Hello everyone, So I have this problem which happened only three so far since I formatted and reinstalled winxp about three weeks ago. Broni helped me scan my computer very thoroughly at the virus removal section, but he couldn't find anything suspicious. He did however advise me to post my problem here if it returns. It did, so I'm posting: So suddenly the computer would start reacting wirdly to muse clicks; I can't even explain all of the phenomena other than everything just goes crazy - the right mouse button brings out the menu but pressing items or double clicking other items doesn't work - they just don't respond. The "start" from the start button disappears and only a green rectangle remains. The clock and the icons near the clock disappear and when I try ctrl alt del it brings out an error message: "taskmng.exe - Application Error - the application failer to initialize properly (0xc000012d). click on OK to terminate". Than when I try to shut the PC down it either brings out the log off panel instead of the shut down one and becomes all graphically messed up and transparent. I hope that you guys will be able to figure this out. Thanks in advance, Max.
