I just built the system, but it can not POST. The green lights turned on after plugging in the power cord. All the fans spin after turning on the power, but NO video , NO beep. Following is what I use

 

Asus P5Q pro

Intel dual core E8500

OCZ reaper DDR2 800 2GB*2

Asus EAH 4850 Top 

 Corsair 550W power supply

Antex p182 Se case

 

I have tried removing 1 of the 2 RAMs, clearing the Cmos, but nothing changed. Anybody has ideas of what I should do.

 

 

Thanks a lot 

buddy get the 4pin power connector plugged in and make sure the 6pin pci power connector fixed too.

 

I did plug in the 6pin pcie power for vga

but there is not a 4 pin  power. The ATX 12V power is a 8 pin power, and I did plug it in

Try with NO RAM, does it beep now?

I would take it out of the case, and lay it on some cardboard, use only the PSU, system speaker, video card if needed, cpu and hsf, and one stick of ram. any luck?

Tried No rams, still no beep

 

Take the mobo outside the case,  with only cpu, video card, one stick ram plugged, still got nothing, but I found a small blue jumper cap on the mother board. I am thinking maybe that's the reason, but I checked all the jumpers indicated in the menu, all of them seem to have a cap on them. Any one has any idea of where this jumper come from.

 

Thanks 

If the motherboard has CLRTC by where the three pin connector is, that blue jumper is for resetting the BIOS to its defaults.  If I am remembering correctly both P5Q-E mobos I had also had a blue jumper which was near the bottom right if you look at the mobo with the CPU socket at the top left center.  Another way to describe the positioning is to have the motherboard in the position it would be in with the mobo installed in the case and you are looking at it from the side and the tower is in the upright position.  If I recall correctly, that was the only actual jumper on the motherboard for my 2 mobos I had as well.

The CLRCT has already got a cap on it. there is a jumper called ov_nb(overvltage the northbridge) ear  the lower right corner, but that also has a blue cap. I search the whole board , especially the lower right corner for the pins the little cap belongs to but got no luck. :(

Does the manual not spell out all the jumpers for you?  Is there a clr cmos one (if missing from there it could be your problem)

Just found out the jumper cap is for the casis intrusion sensor. Plug it back in there, BUT still got nothing, no beeps, no videos. Really frustrated. SHould I return the mobo? 

I would test the video card and power supply in another computer just to make sure they are good. Ive seen video cards cause mainboards not to have post beeps.

Asus mobos use CLRTC as the name for the CMOS jumper.

Tekran:

Asus mobos use CLRTC as the name for the CMOS jumper.

Oh yea, lol    I been getting all with buttons for it lately. forgot that.

Get rid of the video card, still heard nothing. Get rid of the ram, nothing. I am thinking of returning it. I feel terrible.

Don't feel bad.  I am having the SAME exact issue at this very moment.  The only difference from our scenarios is that my asus p5q pro was actually working for a few days.  I went to reformat my drive and when I got back home my pc was on but the monitor had no signal.  Now my pc won't post at all and i've tried what you're talking about too, without vid card or memory.  At this point im also inclined to think that my motherboard had died on me.   Everything was in perfect working order too :(
