Geforce 4 ti 4200 problem, need help. I recently got a Chaintech A-GT20, geforce 4 ti 4200 128mb. Sys info: Dell 4400, P4 1.7, 256mb ram DDR. motherboard is Intel 845PT Windows XP The video card DID NOT come with the Dell, it's an add-on. Windows works great. Graphic quality is great. However, any game I play I have a stutter like effect that keeps happening. It appears to happen at certain intervals. It is almost a full pause is what it's like. I've tried getting NVMAX and setting the AGP to 2x, the Intel option. I've tried other settings as well but to no avail. One thing I've heard is that the power supply not being beefy enough could be a problem, but is it this kind of problem. The Dell's, per their web site, all come with 250watt power supplies. Unfortunately the one in my ssytem does not say on it. Any help would be greatly appreciated. Many thanks in advance.
