p4p800 boot failure too

I'm having the exact same problem. Just RMA'd 1st one to newegg, installed 2nd one. machine seemed stable for several hours -- ran memtest on my 2 sticks of Crucial DDR3200 512MB with 0 errors.

I was in the BIOS about to tweak mem settings per AnandTech article, but saw a "Burst Length" one I didn't recognize so I set it back to defaults.

I may have set the Performance mode to Turbo before rebooting, now nothing!

BIOS reset with jumper & battery has no effect.

Arrggggghhhh...

I left the PSU leads disconnected, the battery removed, and the reset jumper on 2-3 all night.

I didn't have any luck with using the Insert key during power-on.

I'm starting to regret jumping from AMD & Epox.

Ralph -- sounds like the identical problem as I'm having. I don't have any CL2 mem here. may see what the smallest, slowest CL2 mem I can find.

However, my board doesn't even generate beep codes now (with CPU and RAM removed). Prior P4P800-Deluxe MB would at least do that. I'm wondering if it's totally dead now!
