Graphics card help!??

i have windows vista ultimate, my motherboard is a asus p4s800-MX. before my graphics card was a ati radeon 128 mb and it worked fine on vista, bet then after a while it nearly overheated because i smelt it burning so i quickly took it out luckly it was fine. I used the integrated graphics card, which is a SiS 661 FX. after a while i tried putting back the ati radeon but now everything is slower. eveyrthing shows up slower than before. is this because of the graphics card??? if it is, isnt the ati radeon better than the SiS??

Wow, you SMELLED it burning? That seems like there could be some extensive damage to your graphics card. I'm surprised it still works. It could just be that some circuit that controls accelerated graphics is broken. If it's still under warranty, I suggest you return it.

Did you install the proper drivers for the 2nd card and configure it for your system? If so, then its a good bet that its slower than the first one.

You might just have a bad card - if your graphic card is still under warranty then contact ATI and have them replace it.

Check your case to make sure you have sufficient cooling inside your computer, that could be the cause why it overheated. Further you want to make sure that it doesn't happen again.
