I think I found the problem. On the computer, the memory is only 1Gig (the ram) so it might explain the reason why it goes in black screen. the machine is 5 year old so I'll try to expand it to 2 gig to give a lil bit of "fresh air". I uninstalled McAfee successfully. thank you for your program. Avast seems to be ok, I'll monitor it on both computer.
So far, both machine behave well.
I can say, another mission accomplished for ken545
