Video card not working, pls help

[mirrorlake]

I have this problem for weeks and don't have a clue. I am using a Abit KT7A with raid mobo and a radeon 7500 video card. It was all working fine before I went aboard for several months. When I came back, I can't get anything on the monitor. The video card is working well at my friend's PC. When I tried his card on my board, still no signal. So the problem is on the mobo? The weird thing is I've had this same problem before and that was why I replaced the mobo (Asus K7A). Has anyone had any similar experience before or I am just the unlucky one? Do you have any suggestion?

thanks!

yup... i've had kt7a+ before and the video just died... i tried many things until i concluded that it was the mobo... returned it, they replaced the mobo, and it works fine now
