Hi Lee2008,

Firewire is a type of connection. Perhaps if you provide the model of your computer, we'll know if you have a problem.

The model is a dell studio 540 Quad core processor, 6 g ram, 9800gt graphics card (nvida). BFG 550 watt power supply. Baracuda 500g hard drive. I thought I would go into detail since I did modify this computer a little. I just installed another fan that was a plug in. I did plug it into a component on the power supply. I did this so that way it would cool the tower off a bit since nvida likes to run hot. I also have another question. I am getting alot of low frames per sec or a jump from 60 to like 30 even lower in world of warcraft. I have modify firewall in windows, allowed ports to my router, and had to install a new hard drive into my computer since the old went bad. This was done yesterday. I installed a fresh copy of vista, updated all software and drivers known to man kind. I have also rolled back some drivers also, still nothing seems to improve. I calculated how many hours I have used up on my power supply since they said it was 18000 hour power supply. I have used up close to 15000 hours. So basically my question is  could my supply battery gone bad since I first purchased it. I have done a burn in testing that is where I found the firewire issue. So I am kinda curious my frames per sec issue has anything do with this firewire thing or two separate issue. So I try and get another battery and see if it works or is this firewire issue cause a problem. What do I need to do to fix it.

Thanks again

ok thank you. Any ideas on my frames per sec.

So I am kinda curious my frames per sec issue has anything do with this firewire thing or two separate issue.

separate issue

firewire is most commonly used for the importation of video files from a camcorder

The Studio systems are not really geared toward gaming. If you need suggestions on a video card upgrade, try over in the desktop video board.

Good luck!
