You install it and if it works it's OK, if not something doesn't work.

-> There are motherboard testers but they do cost millions and why we just swap boards if we suspect a board.

--> More about the new dead home built PC issue. Most often you find out the new builder installed EVERYTHING rather than worked up to the full machine. That is, wouldn't we setup the bare minimum parts to get BEEPS and power ups prior to adding video, drives and such?

I have tried bare test, no pci cards, no drives even no fans just cpu +cpu fan(coolmaster V8) +1X8gbDIMM.
MB tries to boot 5sec. then turns off than tries again, again, again so on.

Sounds good.

As the video is showing it trying to boot the next step is to see if we can boot from CD/DVD/USB, etc.

PS. Boot defined.

Boot is exactly that. It's trying to boot the OS.

Power cycling is not "boot" so let's be sure we are talking the same lingo.

Sorry guys.
There is a term problem.
It is not trying to boot, it tries to star. There is no video.

So power cycling?

To sniff this out a lot more details are required. One member was popping a new MB, CPU and such on a small case 230 Watt PSU. It just cycled on and off with the member wondering why. (it was the PSU too small issue.)

Some guys told me that if the bios has not upgraded only one slot 8GB DIMM can cause this problem.
What u guys think?

I think more testing is needed.

In reply to: 8GB DIMM

If you suspect this, why not unplug it? If it's that, the power cycling will stop and it will power up and stay up.

If it doesn't stay up, well. Let me ask a question.

Why not build -> up to <- the full system. Start with the bare minimum 2 parts (motherboard and power supply) and test that. If that fails you are looking at the bad parts.

Sure it could be mounting posts shorting out the backside but the first 2 part test didn't include the case.

It stays UP
by ksensoy / July 13, 2013 5:45 AM PDT

when I unplug the DIMM, system powers up and stays up.
Power cycling stops.

with only cpu+cpu fan, system stays on.

is that mean that the problem is come from the 8gb dimm?

Almost sounds like it is.

Or your test is still inside some case and the usual mounting post issue is still there.

Bad news
by ksensoy / July 14, 2013 4:00 AM PDT

You were right Bob, problem is something else.
I have tried with a RAM kit 2X2GB DIMM and it stared power cycling again.

If you guys have no better idea, I will take the machine to repair shop tomorrow.

thnks for all.

If I were to guess. The PSU is the issue.
by R. Proffitt Forum moderator / July 14, 2013 10:16 AM PDT

Try this PSU on another system or any PSU on this one as with only the board, CPU and RAM we only nee a few 100 watts and not the entire 750.
