What should i do?!?

[sirplayalot]

I get CONSTANT rebooting and blue screens with my A64 3500+ Socket 939 and gigabyte K8NS-Ultra and Kingston HyperX PC4000 DDR500 RAM! I read in a lot of places now that their is an issue with the k8ns ultra and the 3500 winchester core. Also another thing is that CPU-Z and stuff say that this mobo is a nforce 250 chipset when its infact an nforce ultra! WHAT SHOULD I DO? Im using the F4 bios from gigabytes site!
