:sigh: Hi, have been sent here from the hijackthis thread as i was having trouble with some spyware. went through a range of processes with tetonbob and got rid of what the scanners had found. however, my computer is still acting up and today whilst i was running my avg spyware scanner again it got cut off again midscan and the screen went dark, it goes dark but not off and i'm not able to do anything, this was the first reason i posted in the hijackthis thread. i thought it was all ok because occassionally the scanners will finish. have had trouble running the kaspersky online one as well as that always stops in the same place and cuts off. and today between restarts i got a white flash and white stripes on screen until the whole screen went black and then when i ran avgspyware again i got a blue screen and then it automatically restarted. i also get the error message "dwwin.exe" dll missing when i shut down or restart. so tetonbob passed me on to here saying he thinks i have an os problem. any ideas as to what is going on and is the error message linked at all to the problems?
