KT7 Problems

[lyzrd]

Hey there just picked up a Abit KT7, Duron 700, 128MB Stick of Memman Infineon PC133 RAM, Antec 300w Power Supply, and a ThermalTake ORB cooler. The system runs great for about 20 minutes and then just start freezing. This also happens if I attempt to play any video file.

Any ideas?

Thanks.

Have you tried striping it down to just video card as only add on?
