m549 overheats video card

[steve roffey]

Greetings all and Merry Christmas!
I have a problem where my video card gets quite hot only in this m549 board. The card is a S3 virge dx, and it worked ok in other machines. This board was in a desktop system, and the power supply was right beside the PCI slot 1. The fan didnt work in the PS so it ran quite hot when i got the machine, and cooked the original video card. I changed it into a tower case, but could not get it to run stable with this new card in PCI 1. Installing it in PC! slot 2 allowed it to operate, so i think that the damage could be on the mainboard itself. The problem is usually when conn3ected to the internet, the screen will go black and the led on the moniter turns from green to yellow, like it is in sleep mode. Touching the video card, it feels hot. just cooling it with my hand seems enough to kick the monitor on again, So I am now running it with the cover off and have a fan blowing into the case. I will try gluing a heatsink on the card, but i wonder is it likely the video cards fault or the mainboard?
P.S. it is running an amd k6233 and is not overclocked 3.5*66
