hi guys, i have a foxconn 45cmx series with an ati radeon hd4650 graphics card. Its been working well but just this morning i switched it on and it came on alright but after loading windows, this message came up "no signal". i took the graphics card out and wiped it clean and reseated it perfectly and it still wasnt working. So i switched to the on board and same message came up. I tried the monitor on my laptop and it worked but i dont know why it doesnt work on my pc. Need help asap. Thanks in advance!!!!
