About a month ago I was trying to connect to my dial-up internet. A message displayed on my computer saying that the modem was not correctly put in. So, I switched the computer off and took it out then put it back in again. The same message appeared when I tried to dial-up and I did the process twice over. The last time that I tried to put the card back into its slot my hand slipped and knocked the power box. It wasn't very hard but it was significant enough to stop the computer from turning on again and it just won't at all, no matter what I do. The computer is from Dell, standing tower and is very compact with everything built into the monitor, such as the graphics card. I've had two people (relatives with background computer knowledge) look at it and think that it might've been the graphics cards which is built in. So, they got an S3trio and tested it in one of the other 'port' 'slot' things which did not work. Another thought they had was that it could be the harddrive, but they think its unlikely. I know it's hard to try and fix the problem without being able to examine or see it, but is there anyone with some ideas as to what might be wrong?
