Hi, I know it's a bit daft but I had no choice. Here goes: I recently bought a Geforce fx 5500 agp to replace my radeon Pro x800 that for a strange reason was rendered faulty after moving home. At first I was glad...I finaly could go on the net ETC...The display is correct but the probleme appears when I play games in 3d. The display freeze for a while every 5 mn the the sound loops. I tried evwerything, updated drivers, also tried clean reinstall with older drivers, scanned for spywares, scanned for viruses...ETC I believe that the problem comes from the heat sink that doesn't allow the heat to be diffused properly. I also got a Xfi fatality lately. Could there be a conflict between those 2 cards. OS: windows XP Ram 1GB CPU: athlon 2400 xp Any suggestion?
