New built PC doesn't POST

[skyeclipper]

Hello,

My newly built PC won't boot. The PS turns on and powers up the motherboard, the video card and the case fans, but that's it. Nothing else happens. Nothing appears on the monitor connected via VGA. I have tested the memory and it appears to be OK even though the MEM-OK LED  has remained on like an angry red eye during all trouble shooting. It has never blinked once. I believe that I have eliminated everything except the motherboard and the video card and possibly the memory.

Also does anyone know if the ASUS P6X58D-E emits beep codes? If yes on beep codes, will they work with external speakers?

Here is the component list:
Intel i7-930 CPU
ASUS P6X58D-E MB
ASUS Radeon 5770 Video Card
CORSAIR 850W PS
A-DATA 6G RAM
ASUS 24” LED Monitor
Western Digital Caviar Black 1TB HD
Lite-on 24X DVD optical drive
 
I am at wits end. If some kind guru could help a skinny, old, bald guy, I would be very grateful.

Any and all motherboards should have beep sounds to warm of hardware malfunction. And they will only work with motherboard-integrated speakers.

Nothing at all shows up on the screen? Can't even get in the BIOS?

Does the motherboard have integrated video? If so, try to unplug the Radeon and boot on the integrated, see if it makes a difference.

Also just to make sure, most high-end video cards require power cables directly from the power supply, are those plugged in?

Ok sorry for being lazy, just google'd your motherboard, and as I can see there is no onboard video. Try to plug in another card if you have one and see if it makes a difference.

There's no onboard speaker, so you won't hear any beep codes.

will they work with external speakers?

If you mean speakers connected through the sound card, no. Usually the speaker comes with the case and you connect it to the speaker header on the board.

These boards do seem to beep, as long a speaker is connected. I found a thread that says this board is fussy about the power supply used, and that it doesn't play nicely with OCZ PSUs.

Thanks for the good info.

Hey,

Good advice guys. I have tried everything that I could. Seems like I won't be able to do much else without beep codes, so I just ordered a crappy internal speaker to replace one I have lost to the fog of time. If that doesn't help with troubleshooting, I will RMA everything.

Thermal paste applied properly ? ?
Sorry i'm late to the party,,,

[AdamLiuu]

ooh,mine has got the same problem.

[blackrainbow]

hmmmm have you made sure all the cables are plugged in, when i rebuilt my naibours pc i for got to plug one wire in and i spent a week testing every thing just making sure the MB did not die..... lucky enought it was just the cable, it could be worth checking

[skyeclipper]

Thanks again for the sage advice.

I am going  to start the build over. My new plan is to buy a crappy little PC speaker and see if the beep codes identify a culprit. If things are still FUBAR, I will ask for more help from you guys.

Thanks again.

Good plan...and Good Luck !

I would suggest that the RAM is a likely culprit. I have encountered similar circumstances in the past, and more often than not, RAM has been the cause. If you can get hold of a single RAM module which you know works reliably, try booting with just that installed. Some motherboards are also very fussy about the type of RAM and the BIOS memory settings. I had an ASUS board a while back which i tried 3 different brands of ram before i found one which would allow booting into BIOS. Once there I was able to manually set the RAM setting to the proper defaults and from then I had no problem with any type of RAM, even the ones which wouldn't work earlier.

If does not solve your problem, I suggest pulling the computer completely appart, then reconstructing it with a bare minimum needed for boot, i.e. just one stick of RAM, and leave out any extra expansion cards such as sound and network cards.

Sometimes the problem is as simple as a component not seated correctly.

Good Luck.
