Blue Screen Of Death.

I have a Windows NT workstation 4.0 installed on an intel 810 chipset motherboard. Intermittently the system crashes to the Blue Screen. The screen reads at the top “page fault in non-paged area.” I am running IE5.0 with service pack 4. I tried running IE5.5 with service pack 6a. with the same results. I’ve tried installing IE first then the SP. I’ve tried installing the SP first then IE. It makes no difference. The BSOD appears mostly when I am in IE moving to links in web sites or to a new website. It also occurs when My computer is accessed ( But far less) If anyone has an idea please let me know
