Question about ASUS P4P800 SE (890552603657) Motherboard
When turned on the fan runs, no beeps no post.
Have checked most of the power fets,seem to be O.K.
Tried memory replacement, CPU,video card,bios chip.
Is there any common problems with this boards?
I have another P4P-800SE board that is the same way.
The best advice I can give you is to remove the motherboard battery (UNPLUG THE PSU BEFORE YOU WORK ON THE MOTHERBOARD) and let the system sit for about an hour. If the CMOS settings are corrupted, removing the battery will erase the corrupted data in the CMOS, which will automatically reset the CMOS to the default settings... Then, plug the battery back into the motherboard, and try to boot the system...
If that doesn't work, you should disconnect EVERYTHING attached to the PSU, and remove ALL of the add-in cards (modem, NIC, soundcard, TV tuner, whatever you have), and install ONLY the CPU, the heatsink/fan (don't forget to PLUG THE CPU FAN IN), ONE stick of RAM... you get the idea. DISCONNECT the HDD, the FDD, the optical drive, and ANYTHING ELSE from the PSU. When you're ready to test the system, you should have ONLY the CPU, the HSF, and one DIMM plugged into the motherboard. Attach the PSU connectors (both the main ATX connector AND the auxiliary 4-pin 12-volt connector) to the motherboard, and try to boot the system. If it works, SHUT DOWN and UNPLUG THE PSU; then install ONE component (the floppy drive, for example), reattach the PSU, and reboot the system. If the system POSTs, shut down, unplug, and add another device. If the system does NOT complete the POST process, the last piece of hardware you installed is probably the culprit.
Take your time with this; be methodical, and make GOOD notes about the steps you've followed, so we can help you work through this problem...
Best of luck to you; keep us "posted" on your progress...
