For some reason, I think I installed my ATI Radeon 9800 PRO 128mb vid card incorrectly. This was my second video card installation but my first video card that required it to be hooked up to the psu. I obviously called my comps tech support so they could walk me through this installation. One thing to keep in mind is that I have two fans installed. The instructions on the 9800 Pro said to install one end of the cable hooked up the 9800 PRO to the psu and the other one to the hard drive. When I called tech support the guy assisting me said to hook one end up to the psu and the other end onto a fan. Af first I thought this seemed logical, I mean the fan is connected to the HD, so why not connect the vid card to the fan. I told him what the instructions said, but he said to trust him. He does build computers for a living. So I trusted him. I've always wondered wether I installed it inccorectly or not. Thanks in advance, I appreciate it.
