I currently have a 1.60 GHZ P4 on a pV4xasd2 VIA Mobo, brand new power supply purchased a month ago with two 256mb DDR Ram sticks. I recently attempted to install a newly purchased intel 865GBF mobo, but after install system would not boot (fans spin, but no post) all supplies meter check ok, monitor ok etc. I then replaced the original mobo and it too would not boot/post. (tested both with only the CPU and Ram installed). At this point I suspected that I had damaged the CPU so I took it too the local shop to have tested in a known good system...tested OK. I did read something in the material of the intel Mobo on a potential differentiation (and thus incompatibility) with the 1.60 P4 that I have and a 1.60a? I've ensured that all the standoffs are OK (not grounding to the chassis) Any ideas?
